Definition - What does Texture mean?
The "texture" of a wine can be a group of adjectives used to describe a wine's mouthfeel and the sensation an individual has on their palate from drinking the wine. A well-rounded description of a wine's texture will start from the initial attack to the finish. This usually includes perception of varying acidity to tannin structure.
WineFrog explains Texture
The tactile sensation of a wine includes its texture. Each wine has a different texture depending on the varietal from which it is made, how the wine was crafted and finished (aging sur lie, barrel aging, etc.)
Most white wines will initially have a present acidity on the initial taste. Some may continue to have the acidity (whether citric, malic or lactic) into the finish. But more elaborated wines, such as an oaked Chardonnay may have a creamy, buttery or spicy texture on the finish.
Red wines can also vary. A Pinot Noir may be slightly acidic upfront with fresh berry notes or have an earthy texture and finish with some oak characteristics, adding tannin to its structure. Whereas, a Cabernet Sauvignon may have a baked red fruits on the front palate and finish with an overall tannic mouthfeel. This can be anything from velvety smooth to almost astringent.
