Seven steps to even better coffee at home…

A while back I shared my Five Steps to Better Coffee at Home as a series. I’ve been thinking about those tips, and how I’ve applied and developed them at home – and I’ve got seven further tweaks that I’ve made to my coffee routine that I think have made a pretty big difference to the quality of my daily brews. So here we go. Some of these were alluded to in that series, but I’d say they’re essential to moving from the basic, through the intermediate, to the advanced (and I’ve got five stupid tips to share with those who want to be like me coming soon…).

Here we go.

Step 1. Storage

I used to be a little lackadaisical about bean storage. Sure. I’d tell other people that it was really important, but then I’d just leave 500gm of coffee in my grinder’s hopper until I’d been through it. It was slack. Lazy. And the difference is noticeable – especially from about 4 days post roast.

Step 2. Weigh everything.

This one has probably been the biggest revolution for me. If the aim of the game is consistency – the best way to achieve that is to use the same amount of coffee every time. A gram either side of your standard dose will throw everything out, and if you’re not paying attention to how many times you’re whacking your portafilter against the bench to settle the grounds it’s easy to lose track of how much coffee is in the basket. Weighing your dose solves this. Weighing the shot afterwards will take us through to point 3. But also helps measuring brew time and brew volume (30 mL in 30 second being the golden yardstick).

Step 3. Understand brew ratio (or take note of it) and flavour profiles

Brew ratio is the weight of the coffee in your cup divided by the weight of your dose. So 30mL from 20gm of coffee is a 1.5. Understanding and measuring this will help you build a profile of the beans you’re using, and help you to deliver the same result day after day (once you’ve found one you like). Here’s my 1.2 brew.

Step 4. Go bottomless.

The bottomless portafilter. The coffee photographer’s favourite tool. Because watching coffee gloop out of the basket is such an amazing and visceral experience.

But going “naked” also removes all the crud that builds up at the bottom of the portafilter (try pulling out the basket and cleaning that sucker from time to time – have you ever done that?). And keeps you accountable when it comes to your dosing – dose wrong and your naked portafilter will let you know by shooting streaming jets of hot ‘spro all over your kitchen.

Step 5. Keep your empty milk jug in the freezer.

This has revolutionised my milk texturing. Using a commercial machine at home (that’ll be in the next series of tips) is great, but it means you’ve got about 7 seconds to steam the milk before it gets too hot. Chilling the jug gives you a little more time, and seems to positively affect the make up of the milk.

Step 6. Clean everything.
Backflush. Yeah. Do it. Not necessarily with the expensive machine cleaning stuff. Looking after your machine will make it last longer. Coffee is oily. Oils build up. Fine coffee particles build up. Keep your stuff clean. Including your portafilters if you don’t have a naked one… This will give you a cleaner taste in the cup. And you’ll be thankful for it.

Step 7. Toss your first shot of the day. And sometimes your second.

I’m not sold on this one yet, and it probably pushes a bit closer towards the “stupid rules for good coffee” – but doing this helps you iron out any issues with the beans you’re using, the temperature of your machine (you should always purge all the hot water in the machine, especially if you’ve got a heat exchange (expensive) machine). The second shot always tastes better – why drink the first just to save a few cents on the 20 gms of coffee you’re tossing.

Five Steps to better coffee at home: Step Five – The milk

Milk can make or break your coffee. Good milk gives your coffee that velvety texture and takes the edge off any residual bitterness. Bad milk makes the coffee appear thermonuclear – have you ever had one of those takeaway coffees that seems to get hotter rather than colder in your hand?

The key to a great milk based coffee (and to latte art) is steaming the milk properly, or if you’re heating milk for your plunger coffee or stovetop – not overheating it.

When you’re steaming milk using an espresso machine there are a couple of things to watch out for. Firstly, you don’t want to boil or overheat your milk. Milk is best at somewhere between 55 and 65 degrees. After 65 degrees the sugars and proteins in the milk start to break down and you end up with sour, burnt tasting flavours. A good rule of thumb (literally) is to put your thumb against the side of the jug as you steam the milk. When it gets too hot to hold your hand against for more than a second or two (and this obviously depends on how tough your hands are – so you might need to experiment) it’s just right. You can buy a milk thermometer, which is a worthwhile investment until you get a feel for what temperature you’re after. It’s also worth remembering that your milk will actually continue to heat up for a little while after you stop frothing it (before it begins to cool down). So stop a little bit below your target if you’re using a thermometer.

The other factor in good milk is texture. Good milk is like silk. It moves as a cohesive unit and has a nice glossy finish. Silky milk, also called microfoam, is what separates good coffee from bad. To get microfoam you need to manage the way air is injected into your milk by your steam wand. Your goal is to merge the milk and the air seamlessly. If you stick the wand too deep or two shallow it’ll blow air into your milk in a disruptive way – giving big bubbles. What you want is a whirlpool effect in your jug (some home machines can’t get a whirlpool – you might need a smaller jug, or just to focus on motion in the jug not just stagnant milk with bubbles forming). Tipping the jug on an angle towards the steam wand and holding the tip of the wand just below the surface of the milk is a good way to get a whirlpool happening. If your milk screams like you’re killing it you probably are.

Mastering milk will dramatically improve your coffee.

Some tips for getting your milk right:

  • Practice getting the motion in your jug right using water – it’s cheaper than milk and moves in the same way. A small dot of detergent will create a similar effect to milk in colour and texture
  • You want a burst of noise at the start as you increase the milk’s volume, then almost none as you texture the milk in that whirlpool motion. Start with the nozzle of the steam arm near the surface then lower it as you go
  • Don’t overfill your jug – you want your milk’s volume to expand by about 50% and you want enough room in the jug to manoeuvre its position to get the motion right.
  • Get a feel for the temperature you’re aiming for – the thermometer is handy to begin with, but it will interfere slightly in your attempt to get a whirlpool motion happening.
  • Don’t burn your milk – smell a batch of burnt milk to know what it is you’re trying to avoid.
  • Practice latte art – it’ll reduce the bitterness of your coffee by breaking up the crema – try cupping the milk jug in the groove between your thumb and forefinger to enhance control (wrap the rest of your fingers around the jug too – do this rather than grabbing the handle of the jug and pouring like normal).

Five Steps to Better Coffee at home: Step Four – The extraction

You’ve got your coffee ready to go after following steps one, two and three – and now it’s time to complete the science of extracting the coffee flavour and caffeine you’re looking for from your cuppa. Here we’ll provide a few tips on espresso extraction, plunger preparation and a guide to stovetop espresso.

Espresso
Espresso is to coffee what nectar is to fruit juice. It’s thick. It’s undiluted. And it’s the basis of most coffee drinks you’ll buy out and about in Australian cafes.

There are, as in every step of the preparation process, a number of variables to be aware of when it comes to extracting your espresso. Essentially, the temperature of the water, the time taken, and the pressure applied to the coffee are the big three.

Water temperature
One of the biggest (and most common) crimes in coffee preparation is using water that is too hot. A lot of machines will overheat if left on too long. Water will sit in the boiler or thermoblock and heat past 96 degrees (about spot on for espresso). The easiest way to overcome this is to flush hot water from the system before pulling your shot (coffee jargon for pushing the button, espresso machines historically used levers for the process of extracting coffee).

If the water is too cold it won’t cause the coffee oils to separate from the granules, if it’s too hot it’ll get too much oil on the way through. Leaving your coffee bitter. If you like bitter coffee use water that is too hot and extract for too long – it’s all about personal taste.

Shot time
The time taken for a shot is important – if the water is in contact with the coffee for too long it absorbs too much coffee oil and becomes bitter, if the water is in contact with the coffee for too short a time (if the coffee shoots through the coffee quickly) it won’t pick up any of these oils and will taste like brown water.

The Specialty Coffee Association of America, a leading authority, suggests ideal shot times of 20 seconds, the generally accepted principle is that between 20 and 30 seconds is ideal.

Pressure
Until recently playing around with pressure during the shot has been largely impossible (this is changing with the latest and greatest commercial machines). When it comes to home machines it’s a matter of finding a machine that will pump water through your coffee at about 9 bar of pressure (15 bar machines are a little misleading).

Plunger tips

  • Boil water.
  • Grind coffee coarsely use about 8gm per 250mL of water.
  • Pour the boiling water into the plunger to heat it (and put the plunger part in.
  • Let the water cool a couple of degrees.
  • Add the coffee
  • Stir and replace the plunger
  • Plunge after 3-4 mins. Push down firmly but slowly.

Stovetop tips

  • Put in less water than recommended on the box, use more coffee than for machine produced espresso.
  • Tamp the coffee (not too hard).
  • Start with hot/boiling in the chamber (use a kettle first). You’ll need to wear an oven mitt or something as you screw the top on.
  • Put on medium heat, use a pre-heated element.
  • As soon coffee starts flowing remove it from the heat.

This should produce thick and rich stovetop coffee with a layer of crema.

Five Steps to Better Coffee at home: Step Three – The Dose

Once you’ve got your supply of fresh beans and your grind sorted it’s time to make your coffee – the next step where coffee often fails is in the “dose” – in espresso preparation this is the amount of coffee ground and tamped into your portafiller basket. The portafiller is the fancy name for “the handle that goes into the machine.”

The amount of coffee used per cup is also important in all other methods of coffee preparation, but it is one of the most controllable variables in your coffee preparation routine. Some baristas seeking to control every variable to the nearest micro detail will even weigh the ground coffee before making their drinks. Others will develop a consistent routine to ensure they get the same result every time.

When it comes to espresso getting the dose wrong can have profound impacts on your extraction, too much and the coffee will stall or pour too slowly. The ideal for espresso is for about 30mL in 25-30 seconds, a shot that takes longer, called a ristretto, is thicker, oilier, and becoming increasingly popular in specialty cafes. Ristrettos can be achieved by increasing your dose.

The basic routine for espresso dosing is to grind your coffee into the portafiller basket until it is heaped over the top. A good tip at this point is to use the double shot basket even when you’re only going to use a single shot. It tastes better.

Bang it against a flat surface a few times (aim for the same number every time) to settle the coffee – you don’t want big gaps or different densities in the puck your coffee will form in the basket – having uniform density means the water has to travel through the coffee evenly.

Next, level off the coffee with a flat surface (use the same thing each time – most baristas use their fingers, but you can use the back of a bread knife or buy expensive dosing tools). Volume is more important than weight – different beans have different densities and it’s important to have the same volume of coffee in the basket each time rather than the same weight, but a ball park is 14gm for a double shot.

Then tamp (push down on) the coffee firmly – some people suggest tamping with 15kg of force (you can practice on bathroom scales, practice pushing down on them with your tamper/flat round surface until it reads 15kg or thereabouts). When the coffee is tamped properly you should be able to flip the portafiller upside down without getting coffee all over your bench, once you’ve got the coffee in the basket it’s time to extract your shot.

When it comes to dosing for your plunger coffee or filtered/percolated coffee there are ideal ratios of coffee to water – that are also best calculated using volume. For a plunger, also called a “French Press” or a presspot, the ratio is one heaped tablespoon per cup of coffee. Brewed coffee (percolaters, drip filters, etc) needs about two tablespoons for one and a half cups.

Five Steps to Better Coffee at home: Step Two – The Grind

So, with step one complete, you’ll have the best beans for the job. The next step in any preparation of coffee is turning the beans into coffee ready for your machine, pot, or plunger.

The fundamental principle of coffee preparation is reproducability. The one commandment of coffee making is though shalt control your variables. We’ll move on to aiming to consistently reproduce the same routine in the next step – but getting the grind is fundamental.

Grinding immediately before use will dramatically enhance your coffee. But not all grinders are created equal. There are two “families” of grinder – burr and blade. Blade grinders aren’t ideal. They’re slightly better than nothing. But unless you do exactly the same thing every time with the same number of beans at the same weight being bashed by the blade the same number of times, you’re not going to get consistency. You’ll never get uniform sized particles and you’ll probably overheat the coffee particles due to friction. If you grind too fine you’ll overwhelm yourself with coffee that has too much oil and is too bitter.

They are a good stepping stone to improving your coffee at home – and if you want to start off with a blade grinder here are some tips:

  • Don’t hold the button down for ages and batter the coffee into dust.
  • Pulse the button for short bursts (two to five seconds) to avoid overheating the ground coffee.
  • For a fine grind go for about 20 seconds of these bursts, for a coarse grind aim for around 10 seconds.
  • These work better for plunger and filter coffee than for espresso.

Burr grinders are more expensive. But with reason. They are more mechanically complex and they produce a better result. The burrs lock together like cogs crushing the coffee into evenly sized particles. You can control the size of the particles by moving the burrs closer or further apart. You need a different sized particle for every machine and for every different brewing method (extra-fine for Turkish, fine for espresso, medium for drip filter and large for plunger).

Tips for choosing a burr grinder

  • Be prepared to spend more on the grinder than the machine (unless you’re buying a $1000 plus machine).
  • Look for maximum adjustability in the grind size, “stepless” is better than “stepped”…
  • Be prepared to waste some coffee finding the right settings.
  • Clean the grinder regularly to avoid build ups of stale coffee.
  • Steer clear of dosered grinders for home use (grinders like they have at cafes with big chambers on the front).

A good guide to burr grinders available in Australia can be found here.

Five Steps to Better Coffee at home: Step One – The Beans

Coffee was discovered almost by accident, when a young African goat herder noticed his goats’ increased energy after they had chowed down on some funny looking berries. After much experimenting and many years of experimenting, turning the seeds of these berries into a drink became the preferred method of consumption.

Good coffee at home is just five easy steps away from reality. If you’ve wondered what the difference between the coffee you get in your favourite cafe and the stuff you produce at home is, and why yours doesn’t taste the same, then there are some simple factors that can go a long way towards making your coffee dreams a reality.

Good coffee is a science – but an accessible science. All coffee, be it espresso based, plunger (or French Press), pour-over, brewed, filtered… you name the method… is a matter of combining coffee oils with water. The factors involved in the taste at the end are many and varied – but the most important factor in determining whether a cup of coffee tastes good is the beans. If you put rubbish coffee into the process it doesn’t matter how rigorously you apply the science of coffee. You’ll end up with rubbish in the cup.

There are a lot of factors in the humble bean that will effect the taste of the final product. The ultimate goal is to find a bean flavour you like, and to stick with it (or know how changing the different variables will change the end result). The golden rule when it comes to coffee, and the one that you’ll want to keep no matter your preference for taste, is freshness. Freshly roasted beans, freshly ground. Coffee preparation is chemistry. If beans are not consumed within three weeks of roasting then most of the flavour has essentially evaporated (the beans become stale). If they’re not consumed within three minutes of grinding then most of the oils on the surface of your ground particles of coffee will have reacted to the air around them. You want to maximise the contact of coffee oils with water during the preparation process in order to bring the most flavour out of your beans.

Coffee tasters primarily talk about the taste of coffee in terms of flavour, acidity and body (how robust the flavour is, the consistency of a shot of coffee from watery to oily). In a shot of espresso the oils can separate from the rest of the shot to form a coloured layer called crema. This is full of acidy oil and unpleasant to taste by itself, but it also adds significantly to the body.

Here are the variables in the beans, and the steps you can take to maximise your enjoyment.

Freshly Roasted

Unless you’re prepared to roast your own beans at home (more on that later) you have to put your trust in a roasting company at this point. The key to a great cup of coffee is using your beans between about three days and three weeks of roasting (most coffee rules involve the number three). This rules out most coffee beans sold in supermarkets, and even most beans sold by chain cafes (like Gloria Jeans).

Here are some tips for getting freshly roasted coffee:

  • Buy direct from the roaster. There are boutique and large scale roasters operating all over Brisbane – from big players like Merlo, Campos, and Di Bella, to smaller operations like The Coffee Guy in Clayfield, Litse in Keperra, Veneziano, BlackStar, or Cup in West End… There’s no excuse for not going to these guys – and you’re often paying similar prices per kilo to what you’re paying at Woolworths for better quality.
  • If you can’t buy direct from a roaster buy from a brand that roasts in Brisbane – try to cut out freight times. Don’t buy beans that are imported roasted from overseas or interstate. Avoid cafes that have bags of beans for sale from shelves that look like they sit there for weeks.
  • Wherever possible you should buy beans that come with a “roasted on” label on the bag.

Freshly Ground

Getting the grind right is essential for good coffee (it’s step two in our five steps). But if you’re not sure about grinding your own beans, the sooner you can get the coffee from the grinder to your cup the better. A good rule of thumb for coffee preparation is that you should spend more money on a grinder than a machine. We’ll cover grinding in more depth as we go – but you’ll get better coffee from a $20 stove top and $150 dollar grinder than from a $20 herb/coffee grinder and $150 machine. You’ll get better coffee from a $20 herb grinder than from a bag of pre-ground vacuum sealed beans off the supermarket shelf, and possibly marginally better coffee this way than if you buy small batches pre-ground from a specialty coffee shop.

Tips:

  • If you’re going to buy pre-ground coffee, buy it in small batches. Not by the kilo.
  • If you’re going to invest in a coffee set up for home get the grinder first.
  • It’s ok to start with a hand cranked burr grinder and a plunger.
  • Grind on demand. Don’t do a batch for the week. Avoid cafes that don’t grind to order. Every second counts.

Roast profile

Unless you’re roasting your own beans this is one of those things you don’t have any control over – and can’t possibly know for sure. Good roasters moderate the heat being applied to beans at every stage in a roast. Temperature control throughout the roast effects the even distribution of heat to the batch of beans and within the bean itself. Good roasters get the most out of their beans by considering the chemical reaction that occurs within a bean during a roast.

The visible signs of the “roast profile,” and the best way to characterise the roast as an end user, comes from how dark the beans are. Generally speaking, the darker the roast the stronger the coffee. As beans roast their composition changes somewhat – the coffee oils move to the surface of the beans as they get darker (they also get shinier as they darken). It’s a bit like chocolate – the lighter the beans, the sweeter they are, the darker they are the more bitter/strong the flavour is.  Light roasts also maintain the individual characteristics of different beans (we’ll get to “origin” in a moment).

Most roasters use the “roast profile” to modify the strength of both the caffeine hit from a coffee and its flavour. When a roaster says a coffee is strong they probably mean dark too. Figure out what you like. This is ultimately a matter of preference.

Freshness of green beans

Green bean freshness isn’t as important as the freshness of roasted beans. Green beans can be stored for a few years before roasting. But there is some evidence to suggest that coffees roasted sooner are a big “brighter” or zestier, while they become more mellow and earthy with age. These effects can also be created by using beans from different origins.

Storage

Keeping air away from beans is important. Vacuum sealed, or air tight containers are the best way to keep beans fresh. A simple zip lock bag with a one-way valve is fine. This valve is especially important for very freshly roasted coffee which is releasing gas as it stablilises. A sealed bag of coffee that puffs up between uses is a sure sign that beans are fresh. Drinking beans while they haven’t properly degassed results in a slightly effervescent (and unpleasant) cup.

Many roasters refrigerate their beans and advocate keeping beans in the fridge or freezer – this is on the whole a bad idea. If you do choose to refrigerate your beans it is important to allow them to come back to room temperature before grinding. Cold beans often become moist as they return to air temperature. This moisture is bad.

Blend/origin

The difference in flavour between coffee beans roasted with the same profile is determined by the conditions in which the beans are grown and prepared for roasting. There are heaps of variables in this process like soil acidity, the altitude the coffee is grown at, and how the coffee fruit is dried and stripped from the seeds (which become our beans…). Different origins have different properties which can be appreciated individually as “single origin” coffees or combined to form balanced blends making the most of different varieties. Professional coffee tasters use this tasting wheel to describe the characteristics of varieties of coffee based on taste and smell. Some people think this is a bit like wine tasting or selling snake oil – but it is helpful to characterise coffees based on levels of acidity and sweetness.

The first step towards better coffee is coming to terms with these factors and deciding what it is that you like in your mug. Once you know what you prefer you can begin to pursue that taste in every cup.

Coffee Bean Review: Dandelion, and Driftwood

Last Saturday, given a spare couple of hours and a hankering for breakfast/brunch outside the house, my wife and I decided to head over to Dandelion and Driftwood to try out their food menu. On previous visits we’d stuck squarely to the coffee. That’s what Dandelion and Driftwood are building their reputation on (contrary to some reviews you may have read in the Courier Mail today – seriously, I know Alison Cotes, I spent a few days with her, spread over a few visits, in Townsville. She’s nice. But this review is a little ridiculous. Why would you not start off at a place that prides itself on tea and coffee by drinking the tea and coffee? And why go for the fancy and expensive stuff if you’re just going to bag it for being fancy and expensive).

Anyway. Here are some obligatory photos of the food – because this is ancillary at best to what we’re talking about here.

That’s my toasted man-wich – bacon, egg, cheese, man sauce and potato chips.

Robyn chose the toad-in-the-hole. A triumph of hyphens.

Both were pleasant. But really, like I said. The coffee is the star attraction.

The latte art on this coffee lasted all the way to the bottom of the cup:

This Kenyan was particularly good.

And Robyn tried the tea – which came served in this sensational tea set. Tea isn’t my cup of, well, tea. But it was pleasant enough to drink.

That’s a really long prelude to the actual point of this post (especially at 1,000 words per picture). We left the cafe with two little brown paper bags in hand (and one, empty bag in my pocket – I highly recommend hitting up the lolly cart while you’re at D&D).

The coffee bags, like everything else these guys do, came with a unique touch of class. Bags are sewn shut with an old school cotton spooled sewing machine. At least that’s how I’d describe it. This isn’t even their preferred method of selling beans, because storage is important they suggest what is essentially the coffee bean equivalent of a grab and go system – with specially designed coffee storage jars.

Here are the bags on my kitchen table and ready for testing. I’ve just finished off the Driftwood – having polished off the Dandelion in a couple of days. I’d say the Dandelion is definitely my favourite. It works heaps better in milk.

The Driftwood packs a punch – and when I gave a cup to my mum today she said “it is very rounded and reaches the back of the mouth nicely.” But the Dandelion. Oh. The Dandelion. It’s apparently the more feminine of the two – but wow, as an espresso it’s pleasant, but somehow, when you add milk, it’s magical.


I took this shot from down low because I stuffed up my attempt at latte art…

I whipped up a batch of syphon for each of them – and while I know it’s meant to be a tool for playing with single origins – I’d have to say the Dandelion was the standout syphon option too. The Driftwood was great as a slow poured espresso, and sadly, my last shot (just then) was a little bit of a failure – I think my machine, which had sat turned on all day, was a little too hot. It was tasty and full bodied, but it didn’t have the pizazz that its counterpart offers. So you’d have to choose between flair and substance.

The Dandelion, which was almost as good at home as it is in store. The way it works with milk is a little like alchemy. I can’t stop raving about the coffee from this place – and I’ll continue to send my friends there knowing they’ll be looked after despite what some so called “coffee snobs” might write in the newspaper.

Want less bitter coffee? Just add salt…

Modernist Cuisine is the foodies’ bible. Its writers take food seriously. And unlike a lot of restaurants out there – they also take coffee seriously. So these snippets from the coffee section posted at Eater.com are worth pondering and filing away for your next coffee party. At least one of these tips will improve your coffee at home.

The Cold Portafiller

“The classic example with espresso is if your portafilter is cold, it’s impossible to pull a good shot. It’s going to be sour no matter what… And the portafilters are clean and sitting down in the drip tray, they’re not locked into the machine. You might as well turn around and walk back out. It’s impossible for them to make a good cup of coffee at the point because the portafilter’s cold. They’re going to put the grinds into a cold or even lukewarm portafilter before locking it in and pulling the shot, and the temperature of that portafilter is going to cause the temperature of the water to plummet. And low temperature water going into your grounds is going to make a very acidic brew. So one of the things you want to see is the protafilter even when not in use locked into the machine because that keeps it hot.”

Weighing the Dose

“… we would do experiments where just being off by half a gram, how many espresso grinds you put in, would make an enormous difference in how good the coffee tastes, with everything else being as same as possible. And so it really reinforces the point that if you want constancy, especially when you’re learning a knack for it, you’ve got to weigh. We’re just not that accurate as human beings to judge things by eyeball. We certainly can’t feel in our hands 17 and a half grams versus 18 grams of coffee. That’s just too small of a difference for us to perceive. It makes an enormous difference in the final cup of espresso.”

Salting bitter coffee reduces the bitterness

“… actually sugar doesn’t actually mask bitterness at all, but salt does. The idea with adding a tiny bit of salt to mask the bitterness of the coffee, and the trick when doing this is to get it so you don’t really detect the saltiness. A salty cup of coffee is not tasty, but just enough so it diminishes the bitterness of the coffee. The easiest way to do it is to just add small amounts of saline solution, actually. That’s a very dilute solution of salt, you don’t have to worry about it dissolving at all, and it’s harder to over do it. You can do that in your cup of coffee, you can do it with tonic water.”

Coffee Gear: Aeropress + Coava Disk

Amongst the really awesome presents I received this year were two most bits of coffee paraphernalia – a syphon with its own little butane burner thing, and an Aeropress. The syphon is fun, but has a pretty steep learning curve. I feel a bit like a mad scientist when I’m using it.

The Aeropress is just easy, and the perfect solution for making coffee away from home. So far I’ve used it in the office and on my in-laws farm. It’s also pretty cheap – and at $54 is a great entry to the home espresso quest.

Former World Barista Champion Tim Wendelboe has a video tutorial on his website, which I’ll now post here…

Aeropress brewing guide from Tim Wendelboe on Vimeo.

Out of the box it’s designed to use paper filters. Which is nice, but if you’re after a more permanent filter solution, it comes in the form of these chemically etched filter disks from Coava

Used as directed, Aeropress will provide you with something very similar to espresso (who are we kidding, it’s coffee brewed under pressure – it is espresso). But you can play all sorts of fun games and use it to make filtered coffee as well – here’s a tutorial from Coava themselves.

They used the same method to make a filter cone (which they’ve called a “Kone”).

You can buy the Aeropress from just about any good coffee retailer, you can get an Aeropress and a Coava Filter from my favourite online coffee store, and supplier of my green beans – ministrygrounds.com.au. For the ultimate in portable coffee you can get the Aeropress and Kyocera hand grinder as a package (for $133).

Kones are used in filter coffee makers like the Chemex. Which will be my next coffee frontier.

Campos on Coffee at home

If I was going to give some tips for making coffee at home (and I am, eventually) I’d probably just echo (but in different words) this great set of advice from Campos Coffee’s website. You’ll find it under their “About Us” link.

  1. Buy yourself a good grinder.
  2. Use fresh beans.
  3. Store them well.

Then they’ve got different tips on a few home coffee methods. I love that they don’t buy into the “you can’t make good espresso at home so don’t try” argument that I see trotted out occasionally. That’s just rubbish.
