Espresso Brew Guide
Making espresso to a high standard can seem incredibly daunting and scary when you first start to delve into the wealth of information available. There are many variables to consider and many different ways of making the same coffee taste delicious, plus a never ending list of equipment and gadgets that you're told will improve your drink.
Whilst it's great to read as much as you can and try as many different gadgets as possible, without applying some basic ground rules to your dialling in routine it can all be a little pointless. With that in mind, here are some great starting points when trying to build an espresso recipe.
We'll be keeping it fairly simple here, and just using the grind setting to adjust what we're tasting. It's all about finding the sweet spot for your coffee.
A finer grind will slow your shot down and give you more extraction, which means you'll get more sweetness and increase the amount flavours unique to your coffees origin. However, go to far or "over-extract", and you'll have a bitter and dry tasting espresso.
A coarser grind will speed your shot up and give you less extraction. If you're over extracting and the espresso is tasting bitter, you need to extract less to gain some pleasant acidity and bring your espresso shot back to the sweet spot
