Espresso is a concentrated coffee beverage brewed by forcing a small amount of nearly boiling water under high pressure through finely-ground coffee beans. Originating in Italy in the late 19th century, it is the base for many popular coffee drinks like lattes and cappuccinos. A standard single shot typically contains just coffee and water.
Espresso is virtually fat-free and contains negligible carbohydrates and protein, with a single shot containing roughly 2-5 calories. Its primary nutritional contribution is a significant dose of caffeine and antioxidants like chlorogenic acid.
Culturally, the espresso ritual is a cornerstone of Italian social life, often enjoyed standing at a bar. Nutritionally, it is one of the most efficient ways to consume antioxidants from coffee, delivering a high concentration in a very small volume.
