Frequently Asked Questions
What's the difference between a latte and a cappuccino ratio?
Lattes use mostly steamed milk with a thin layer of foam, while cappuccinos split roughly equally between steamed milk and foam for a denser, airier texture.
Does espresso volume count toward the total?
This calculator focuses on the milk component. Subtract your espresso shot volume from the total drink size before entering it if you want milk volume only.
What ratio does a flat white use?
Flat whites use very little foam, emphasizing a silky microfoam texture with mostly steamed milk, similar to a thin latte.
