Coffee espresso
This is the essence of coffee, expressed in the most concentrated form. Starbucks espresso has a caramel flavor and a strong aroma.
One ounce of espresso is also called a single, while two ounces of espresso is called a double.
Espresso with rich layers is the soul of Starbucks. Its intense flavor, persistent aroma and slight caramel sweetness are at the heart of lattes, cappuccinos and other espresso based coffee drinks. You can also try each flavor individually and perhaps spot subtle differences. Source: Starbucks official website www.starbucks.cn
