What amounts of coffee and water are used in a traditional recipe for double shots of espresso?

In a traditional recipe for double shots of espresso, the standard amount of coffee used is typically around 14 grams, which is widely accepted in espresso preparation. This amount strikes a balance between extracting the rich flavors and nuances of the coffee while producing a well-rounded shot. The volume of water used in this context is usually between 50 to 60 milliliters, which corresponds to the desired extraction time and the overall strength of the espresso that is produced.

Using 14 grams of coffee and 50 to 60 milliliters of water ensures that the brewing process takes place under ideal conditions. This ratio helps achieve proper extraction of oils, acids, and sugars that give espresso its complex flavor profile. It is crucial to maintain this balance, as variations in coffee dose or water volume can lead to under-extraction or over-extraction, significantly altering the taste and quality of the espresso. This precision is key in the art and science of espresso preparation, which places high importance on the coffee-to-water ratio.
