Espresso Fundamentals

A dial-in map for espresso: fix dose and yield, adjust grind and temperature deliberately, and let tasting guide the next change.

Temperature can tune extraction and flavor, but its effect is filtered through puck prep, flow, and machine stability.

Grind size is the main repeatable flow adjustment after dose and yield are fixed.

Extraction is the central diagnostic idea: taste tells you whether to extract more, extract less, or improve evenness.

The espresso machine controls pressure, temperature, and water delivery, but repeatable shots still depend on grinder quality and maintenance.

Dose and yield define the recipe; time helps diagnose flow but should not replace weighing the beverage.
