Resin is the aroma and flavor prominant in Greek Retsinas wines. It is caused by the addition of small amounts of resin to the fermentation. Tavel rosés and American Grenache-based rosés display a greater or lesser degree of resinous odors, while not actually having had resin added to them. Many spirits, beers and meads may also have a resinous character. (Wine,Beer,Spirits,Sake,Mead/Tasting Terms)
