What is the recipe for a traditional single Ristretto shot?

A traditional single Ristretto shot is known for its concentrated flavor and rich body, achieved through a specific coffee-to-water ratio. The correct recipe calls for approximately 7 grams of coffee with a water volume of 12.5 to 15 milliliters.

This combination allows for a shorter extraction time and less water passing through the coffee grounds compared to a standard espresso shot, resulting in a more intense flavor profile. The reduced volume of water helps emphasize the sweetness and complexity of the coffee, making it ideal for those who enjoy a bold, nuanced experience in their cup.

In contrast, the other options involve different amounts of coffee and water that do not align with the traditional method of preparing a Ristretto. These variations may lead to different flavor profiles and extraction levels, which is why they are not considered traditional Ristretto recipes.
