Espresso Brew Guide

Pull a shot you’d serve to anyone.

Espresso is balance: sweetness, acidity, bitterness — in that order, in 30 seconds. Get this baseline right and the rest is fine-tuning.

The recipe

Ratio 1:2
Coffee 15g
Yield 30g
Time 30s
Grind: Fine Water temp: ~93°C

Step by step

Dose

15g of finely ground coffee, distributed evenly in the basket. Tamp level.

Pull (0:00)

Start the shot. By 10 seconds, espresso should appear in the cup.

Watch (0:00–0:30)

Look for golden crema. Pale yellow = grind too coarse. Dark/black = too fine or over-extracted.

Stop (0:30)

Hit 30g in the cup. That’s your shot.

Diagnose

Sour and fast? Grind finer. Bitter and slow? Grind coarser. Adjust one variable at a time.

Pro tips

Sour means grind finer

Acidity comes out first. If your shot tastes sour, you didn’t extract enough — go finer to draw more sweetness.

Bitter means grind coarser

Bitterness comes out last. If your shot is bitter, water spent too long with the coffee — go coarser.

Crema colour is the cheapest diagnostic

Golden = on. Pale yellow = under-extracted. Dark / black = over-extracted.

Distribute before tamping

Channels through uneven beds destroy a shot. Even distribution > hard tamp.

Fresh roast matters

1–3 weeks post-roast is the sweet spot. Field bags are dated on the back.
