single espresso
A single espresso contains approximately 75-100 mg of caffeine per shot with minimal calories. It provides chlorogenic acid and other polyphenolic antioxidants derived from the coffee bean.
About
A single espresso is a concentrated coffee beverage produced by forcing hot water under high pressure through finely ground, compacted coffee beans (typically 7-9 grams for a single shot). Originating in early 20th-century Italy, espresso represents a distinct brewing method that differs fundamentally from drip or pour-over coffee in both technique and result. The process—extraction under 9+ bars of pressure—forces water through the coffee bed in approximately 25-30 seconds, producing a small volume (approximately 1 ounce or 30 milliliters) of concentrated liquid characterized by a rich crema (a layer of emulsified oils and carbon dioxide bubbles on the surface), bold flavor, and full body. Single espresso shots are distinguished from double shots (which use roughly twice the ground coffee) and serve as the foundation for most espresso-based drinks.
Culinary Uses
A single espresso functions both as a standalone beverage consumed in small quantities and as the base ingredient for numerous coffee drinks. In Italian tradition, it is consumed as a quick, intense caffeine delivery, often followed by a glass of water. Beyond single consumption, single espresso shots are combined with steamed milk to create macchiato, cortado, and other milk-based beverages, or diluted with hot water to produce Americano. Espresso also features in culinary applications including tiramisu, coffee-flavored desserts, and savory dishes that employ its concentrated flavor. The intensity and complexity of espresso—derived from the rapid extraction of soluble compounds and oils—provides a flavor profile that bridges bitter, sweet, and acidic notes, making it versatile in both beverage and culinary contexts.
