03 / How it works

How it works

Coffee (g) = brew water (g) ÷ water-to-coffee ratio. For example, 500 g of water at 16:1 needs 31.25 g of coffee.

Before you brew

The water input is what you pour, not the finished drink. Grounds retain water. Ratios here are editable examples, not a universal recommendation; use your brewer’s capacity and adjust to taste.
