Summarizing description (lat. fabric, fibre) for the taste impression of a mostly red wine in the context of a wine address. The criteria here are viscosity (soft and thick) and above all the proportion of tannins. A "good texture" means that the wine is creamy (soft) and concentrated on the tongue. Descriptive attributes are velvety (silky) or astringent. Related but more comprehensive or comprising much more components (such as alcohol content) than texture are body and structure.
The glossary is a monumental achievement and one of the most important contributions to wine knowledge. Of all the encyclopaedias I use on the subject of wine, it is by far the most important. That was the case ten years ago and it hasn't changed since.Andreas Essl
