In former times, common term for cellar-technical measures, whereby primarily the clarification of a wine was understood. In this process, part of the wine (about 10%) was taken out of the barrel, mixed with isinglass and then carefully returned to the surface of the wine. The precipitating flakes then slowly sank to the bottom of the barrel and clarified the wine. The etymological explanation of the word "flight fining" is probably that particles sink to the bottom or "fly to the bottom" in the process. In the meantime, however, fining is a generic term for many different techniques in the cellar. This also includes the treatment of wine faults and the stabilisation of the wine. See also fining.
The Wine lexicon helps me to stay up to date and refresh my knowledge. Thank you for this Lexicon that will never end in terms of topicality! That's what makes it so exciting to visit more often.Thorsten Rahn
