Making really, really good espresso is tough. You need to put in a lot of time, learning and patience to get top results. You’re going to need freshly roasted, awesome quality coffee (we know where you can get some). Not to mention a good home machine and decent (read expensive) burr blade grinder. You’ll also need to be accurate, passionate and keep your mind and equipment clean to get the results. Beware, this way madness or Nirvana lies…Breathe in, breathe out. Put yourself in that happy place. No one likes you or your coffee when you’re like this.
- Take out your group handle. To get the tastiest flavours from your espresso, make sure it’s clean, warm and dry.
- Purge the shower screen. Running the water through for a few seconds will ensure the water temp is spot on and clean for the shot.
- Throw your group handle onto your set of scales and tare off. This will let you control the dose to a tenth of a gram, making it nice and easy to reproduce your results when you find that coffee nirvana.
- It’s time to grind those beans. Investing in a really good quality burr grinder is the perhaps most important step in producing great results, as you want to be able to control particle size and dose. Grind the coffee into the centre of your handle and make sure it is nice and evenly spread.
- Put your handle back on the scales to check/correct your dose. There are many different basket sizes out there but generally a good starting point is 19-21g.
- Distribute. They’re a few different ideas about the best way to create an even bed of coffee, but start off by horizontally tapping your handle with your hand to even out the surface.
- Ok, pick up your tamper. Have you named it yet? Make sure your tamper is a perfect match for your basket size. The tampers supplied with home machines are often cheap and nasty, so you might consider investing in a professional one. Now, grasp the tamper and press down on the basket, making sure it’s flat and even. You want to apply about 15kg of downward force, which is a difficult concept and not something you do every day. We think of it as the amount of force you’d use to squeeze an extra bag in a full bin. If you really want to geek out, grabbing some bathroom scales and double checking may be a good idea.
- Grab your scales (not the bathroom ones!) and put them up on the drip tray. Place your cup on and tare off again, setting up to measure your shot length in grams. If the coffee you’ve bought doesn’t come with a recipe, using a ratio between 1:1.5 and 1:2 will be a good spot to start. What on earth does that mean? The ratio is a proportion of dry coffee to wet espresso. Our first ratio with a 20g dose would mean we are getting a 30g espresso (20 x 1.5), where our second ratio would yield 40g of espresso (20g x 2). Controlling this variable is crucial to getting the best flavour from your espresso.
- Ok you’re ready, cup’s ready, coffee’s ready, time to insert the handle and press “go”. You want to start the extraction as soon as you put the handle in, leaving it in contact with the hot shower screen is a guaranteed flavour wrecker. Watch your extraction, it should begin with a drip, not a gush or spurt, the drip will build to a gentle stream. The entire show from start to finish should be between 25-30 seconds.
- Now taste. Chances are you haven’t got it right, first shot of the day. Have a look at your puck. Wet & mushy? You may have under dosed. Dry & hard? You’ve probably over packed. Get your scales out. Was the extraction too fast & the taste thin? Adjust your grind finer. Too slow? Adjust coarser, tamp lighter…
- Practice. Taste. Repeat. Learn.
