Aging Wines

[Innkeeper]

The one part of your question not covered in the posting Drew referred you to is the part about "addictives" being added to the wine. No kind of substance is added to wine to make them age worthy. What a wine needs as a result of grape quality and winemaking expertise is substance resulting from concentration and alcohol level, ample tannin coming from contact with grape skins, and acid which occurs naturally in the grapes. These things work on each other naturally to improve the quality of the wine with age.
