What is the primary characteristic of a ristretto shot?

The primary characteristic of a ristretto shot is that it is extracted quickly, leading to a more concentrated flavor. Ristretto is essentially a short shot of espresso, created by using the same amount of coffee but extracting it with less water than a standard espresso shot. This shorter extraction time allows for a focus on the sweeter, more aromatic compounds in the coffee, resulting in a rich and intense flavor profile.

The quick extraction minimizes the dilution of flavors often associated with longer extractions, which can pull in more bitterness and acidity. As a result, a ristretto tends to be thicker and more syrupy compared to regular espresso, making it a favorite among those who appreciate bold, complex flavors in their coffee.
