What does decanting do to a wine?
QUESTION: What does decanting do to a wine? There are two reasons to decant a wine. The first reason is to remove the sediment that can build up in a wine over time. Sediment is particulate matter that has fallen out of the wine. It is safe to consume, but some find it unpleasant and unattractive. The older the wine, generally the more sediment, although certain types of grapes produce more than others. To decant a wine for sediment, stand the bottle up in a cool place for a few days at minimum.
