What is the recipe for a traditional double Ristretto shot?

A traditional double Ristretto shot is characterized by its concentrated flavor and reduced volume compared to a regular espresso shot. This is achieved by using a specific coffee-to-water ratio that enhances the sweetness and body of the coffee while minimizing bitterness.

In the case of the correct recipe, using 14-20 grams of coffee with 25-30 milliliters of water aligns perfectly with the typical preparation of a double Ristretto. This ratio allows for a shorter extraction time and yields a more intense flavor profile, which is the hallmark of a Ristretto shot. The coffee used in a Ristretto is typically ground finer than that used in regular espresso, further contributing to its rich and concentrated taste.

The other options do not meet the standard specifications for a double Ristretto in terms of coffee dosage or water volume. For instance, using only 10 grams of coffee is insufficient for a double shot, while options suggesting a larger water volume would result in a different extraction profile, moving away from the intended characteristics of a Ristretto. Similarly, the ratio of 7 grams of coffee is more appropriate for a single espresso shot, again not aligning with the requirements for a double Ristretto.
