Espresso is coffee brewed with pressure through a fine, compact bed of grounds. Three numbers decide how it tastes: the dose of dry coffee, the yield of liquid in the cup, and the time the shot takes.
This recipe uses a double basket and a ratio of about 1:2, which suits most espresso roasts. Lighter roasts often taste better with a longer ratio, around 1:2.5, and slightly hotter water.
Classic 1:2
The standard double shot most espresso roasts are built for.
18 g · 1:2.1 · 25 to 32 seconds
Ristretto
A shorter, syrupy shot with more body and less bitterness.
18 g · 1:1.5 · 20 to 25 seconds
Light roast long shot
A longer ratio and hotter water to open up lighter roasts.
18 g · 1:2.5 · 25 to 35 seconds
Turbo shot
Less coffee, a coarser grind and a very fast shot.
15 g · 1:2.7 · 10 to 15 seconds
Blooming espresso
A pause after preinfusion for a sweeter, more even shot.
18 g · 1:2.5 · 0:50 to 1:05
Lungo
A longer shot with more water through the same puck.
18 g · 1:3 · 30 to 40 seconds
Change any amount and the whole recipe scales with it.
Run a little water through the group head to flush it, then dry the basket.
Grind 18 g of coffee into the basket and spread it evenly so there are no clumps or gaps.
Tamp firmly and level, then wipe any loose grounds off the rim.
Lock the handle in, put the cup on the scale and start the shot and the timer together.
Stop the shot at about 38 g in the cup. It should take 25 to 32 seconds.
Taste it. Change one thing at a time, usually the grind, and pull another shot.
Grind finer. If it is still sour once the time is right, increase the yield a little.
Grind coarser, or stop the shot a little earlier.
Water is channelling through gaps. Break up clumps when you distribute the coffee and tamp level.
