Espresso is a short, concentrated, unforgiving extraction, and it rewards different choices from filter.
Roast level
Medium is the safe answer. Developed enough to be soluble in 25 seconds, sweet, with body.
Light roasts as espresso are excellent and demanding: finer grind, hotter water, longer ratio, and a grinder good enough to extract them evenly.
Dark roasts give crema and bitterness and little else.
Blend or single origin
Blend if you drink milk. Milk flattens acidity and delicacy and rewards body and sweetness, which is what a blend is designed for.
Single origin if you drink espresso black, and expect it to be lopsided in an interesting way.
Age
7 to 21 days from roast. Espresso is where too-fresh coffee misbehaves most — gassy, unstable, blonding early.
Process
Washed for predictability. Naturals as espresso are intense and can be superb, and they are also more likely to taste boozy or fermented in a concentrated form.
What to avoid
Pre-ground, always. Anything without a roast date. Oily beans, which clog grinders and taste of roast.
The starting ratio
1:2 in 25 to 30 seconds for a medium roast. 1:2.5 or 1:3 for a light one.
Then adjust to taste, one variable at a time.
