Various processes for the treatment of grape must in order to remove insoluble or undesirable suspended solids or particles (grape skins, pips, stalks and pulp). Appropriate must treatment is very important for optimum fermentation and the prevention of fermentation errors. In contrast, similar techniques are referred to as fining for a young wine (young wine), although the terms or procedures cannot be completely clearly separated and are sometimes used for both. See different clarification techniques for must and/or wine under degumming, filtration, flotation and centrifuging. Complete lists of the numerous vinification measures and/or cellar techniques, as well as the types of wine, sparkling wine and distillate regulated by wine law are included under the heading vinification. Comprehensive information on wine law can be found under the keyword wine law.
For me, Lexicon from wein.plus is the most comprehensive and best source of information about wine currently available.Egon Mark
