Calculator cluster
Brew ratios & dosing
Coffee-to-water ratios, espresso yield, cold brew dilution, flash brew and Americano balance.
Brew ratios & dosing
Americano & Long Black Calculator
Combine espresso yield and hot water into cup mass, espresso percent and dilution ratio. Americano is water then shot; long black is the reverse.
Brew ratios & dosing
Coffee to Water Ratio Calculator
Turn a brew ratio and coffee dose into water mass and cups for V60, Chemex, AeroPress, French press and espresso. Weigh both sides; scoops lie.
Brew ratios & dosing
Cold Brew Dilution Calculator
Dilute a cold-brew concentrate to a drinking brew ratio. Enter concentrate mass and the two ratios to get water to add and final drink mass.
Brew ratios & dosing
Espresso Dosing & Yield Calculator
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.
Brew ratios & dosing
Iced Coffee Flash Brew Calculator
Split a target iced coffee into hot brew water and ice so the melt lands on your brew ratio. Enter dose, total beverage and ice mass.
