What is mouthfeel in coffee?

Mouthfeel describes the physical sensation of coffee in the mouth beyond simple flavour - the tactile qualities of texture, weight, and how the liquid interacts with the surfaces of the mouth and tongue. It's closely related to body but captures a broader range of sensations, including smoothness, silkiness, astringency, dryness, and coating quality.

Where body specifically refers to the perceived weight or heaviness of the coffee, mouthfeel encompasses the full tactile experience: a coffee can have medium body but silky, smooth mouthfeel; another might be full-bodied but slightly drying or rough in texture. Both attributes are relevant to quality assessment but describe different dimensions of the same sensory experience.

Mouthfeel is influenced by the concentration of dissolved solids, oils, and colloidal particles in the brewed coffee - which in turn reflect the green coffee's density and cellular structure, the processing method, roast level, and brewing method. Washed coffees generally have cleaner, lighter mouthfeel than naturals; espresso has heavier, more coating mouthfeel than filter coffee from the same beans. For buyers evaluating green coffee, mouthfeel contributes to understanding how a coffee will perform across different brew formats and market applications.
