What does "body" measure in coffee?

The term "body" in coffee refers to the richness and thickness perceived on the palate. It is a key component of the coffee experience, contributing to how full-bodied or light a coffee feels when it is consumed. A coffee with a full body can feel creamy and rich, often coating the mouth, while a lighter-bodied coffee may feel more delicate and refreshing. This characteristic is influenced by factors such as the coffee bean type, brewing method, and roast level.

Acidity refers to the bright and tangy flavor aspect of coffee rather than its body, while caffeine content is a separate measure that does not relate directly to the mouthfeel. Aroma, although important for the overall flavor profile, pertains to smell rather than the tactile sensation known as body. Thus, the correct understanding of body as richness and thickness enhances one's appreciation of the diverse range of coffee profiles available.
