Brew ratio

Definition

Brew ratio compares dry coffee to liquid. For pour-over it is usually coffee : water (1:15–1:17). For espresso it is dose : beverage yield (1:2 is a typical starting double). Changing ratio changes strength more immediately than changing grind. Weigh both sides; volume of a crema-topped shot is a poor proxy for grams.

  Convert basket dose, brew ratio and shot time into beverage yield and flow rate. A 1:2 in 25–32 s is a starting point, not a religion.
