The foundation of all our Lattes, Mochas, Macchiatos and more, and the heart of our beverages, is our perfectly pulled espresso. Our baristas pull each intensely rich shot within a precise five-second window and ensure each has three distinct layers—or they toss it out and start again. It's been this way at Starbucks for over 40 years, because we believe that crafting the perfect espresso is the key to crafting the perfect drink.
