Designation (also sinewy) in the context of a wine evaluation and wine address, which certifies a "good constitution" and thus storability or longevity due to a corresponding content of total extract and acidity. The variation "fine-nerved" is a somewhat more subtle form. Both terms are also often used as more descriptive attributes; two examples are "nervy structure" or "nervy body". A related or similar term is racy. Related terms regarding acidity are fine-acid, fresh, lively and tangy. An excessively high or inharmonious proportion of acids is described with the negatively connoted terms aggressive, acetic, edgy, sour and sharp.
I have great respect for the scope and quality of the wein.plus encyclopaedia. It is a unique place to go for crisp, sound information on terms from the world of wine.
