The Clive recipe for espresso is the same as used by the originator of American espresso (and the pioneer of latte art), Espresso Vivacé in Seattle. We use a **1:1.5 brew ratio** (as it stands up to larger milk drinks), **a triple basket** with **20 grams of ground coffee** to extract **30 grams of liquid espresso** in **23 (dark roast)** to 3**0 (medium to light roast) seconds**.
