# Water Temperature

## Role
Temperature affects extraction, but in espresso the effect is entangled with puck prep, flow, and machine stability. Treat temperature as a tuning variable, not a rescue for poor distribution.

## Adjustment
Higher temperatures can help extract dense light roasts; lower temperatures can soften harshness in darker roasts.

## Caveat
Temperature effects can be less direct than expected because flow and puck mechanics also change the shot. [[source:66000000-0000-4000-8000-000000002203|temperature effect]]
