Mouthfeel
Mouthfeel is the physical texture of tea in the mouth, including body, thickness, smoothness and drying astringency, judged separately from aroma and taste.
Definition
Mouthfeel covers how tea feels rather than how it tastes. The main components are body (thin and watery versus thick and full), texture (silky, oily, slick, or rough), and astringency, the drying, puckering sensation that comes from polyphenols binding to proteins in saliva. Different teas are valued for different textures. Gyokuro and good matcha feel dense and almost broth-like. Aged sheng pu'er and well-made yancha are praised for a thick, smooth body. Assam and Ceylon black teas are valued for briskness, a lively astringent grip that cuts through milk. White teas such as Silver Needle are prized for a soft, light, rounded feel. Mouthfeel depends on what the water extracts. Dissolved polyphenols, polysaccharides, pectins and amino acids all contribute, and processing changes their balance. Rolling breaks cell walls and releases more into the cup. Long oxidation turns sharp catechins into gentler theaflavins and thearubigins. Aging tends to reduce harsh astringency over years. Brewing matters too: higher leaf-to-water ratios build body, while long steeps at high temperature push astringency up faster than body.
In Depth
To judge mouthfeel, take a sip, hold it for a few seconds, and move it around before swallowing. Notice whether the tea coats the mouth or runs off it, and whether the tongue and gums feel dry afterward.
To add body without harshness, add leaf rather than time. In gongfu brewing, moving from 5 g to 7 g in a 100 ml vessel with 10-20 second infusions gives a thicker cup with less astringency than steeping 5 g for 60 seconds. Water matters: some dissolved minerals give body, but very hard water flattens texture, and distilled water tends to taste thin. Moderate-mineral filtered water is a safe default.
Do not confuse astringency with bitterness. Astringency is a tactile drying felt on the gums and cheeks; bitterness is a taste on the tongue. A tea can be very astringent and barely bitter, as many strong black teas are.
