What characteristic is indicative of a coffee's body?

The characteristic that is indicative of a coffee's body is the textural sensation felt in the mouth. Body refers to the weight and fullness of the coffee when it's sipped, often described as the thickness or heaviness of the beverage. This mouthfeel can range from light and airy to rich and creamy, and it is a fundamental attribute that contributes to the overall sensory experience of drinking coffee.

Other characteristics, such as acidity, aroma, and sweetness, influence the flavor profile and overall enjoyment of the coffee but do not specifically relate to the body. Acidity pertains to brightness and crispness, aroma affects the fragrance and olfactory experience, and sweetness can describe how sugary or balanced the flavor is. These elements may enhance the coffee's complexity but are distinct from the tactile sensation that defines its body.
