Acidity: Wine Definition
This is something that can be either good or bad in a wine. Good acidity produces freshness, crispness and vivacity; bad acidity can produce sour wine (vinegar). There are different types of acid found in wine or found at different times, and this is a matter for the laboratory to deal with. But in general, somebody who is talking using a wine vocabulary will always mean praise by commenting ‘acidity good’, which implies balance – not too little, not too much. It is essential for a certain type of acidity to be present in any good wine which would otherwise be sloppy and flat. It is this type of good acidity that gives white wines their fresh, crisp character. But as this acidity is pronounced in most young wines, it can be tiring for the taster who has to try a number of them and who generally notices the acidity afterwards.
