Espresso at Home: A Beginner's Guide

Espresso has a reputation for being intimidating. Between grind size, dose, and timing, it can feel like there's a lot that can go wrong.

The good news: once you understand a few core variables, dialling in a good shot at home becomes a lot more approachable.

Here's a simple starting point.

What do you need?

An espresso machine with a portafilter
A grinder capable of a fine, consistent grind
Fresh coffee
Digital scales
A tamper

The basic recipe

A solid starting point for most home setups is:

18g coffee in : 36g espresso out

This gives you a 1:2 ratio, extracted in roughly 25–30 seconds.

Use this as a baseline rather than a fixed rule — every machine, grinder and bean behaves a little differently.

Step 1: Dose

Weigh 18g of ground coffee into your portafilter basket.

Consistency here matters more than the exact number — use the same dose every time while you're dialling in.

Step 2: Distribute and tamp

Distribute the grounds evenly across the basket before tamping. Uneven distribution is one of the most common causes of an uneven, unpredictable shot.

Tamp level and firm. You don't need to press as hard as you think — consistency matters more than force.

Step 3: Pull the shot

Start your timer as soon as the pump engages.

Aim to collect 36g of liquid espresso in 25–30 seconds.

Water temperature around 93–95°C is a reasonable starting point if your machine allows adjustment.

Step 4: Taste

As with filter coffee, taste is the real test.

Shot running too fast, tastes sour or thin?
Grind finer.

Shot running too slow, tastes bitter or harsh?
Grind coarser.

Shot tastes weak or watery?
Try a lower yield (e.g. 32g instead of 36g) for a more concentrated shot.

One variable at a time

The same rule applies here as with filter brewing: change one thing at a time. If you adjust grind, dose and tamp pressure all at once, you won't know what actually fixed — or broke — the shot.
