I keep my wines in a crawl space under my Nor Cal house. Temps there do change with the season but are not as extreme as the rest of the house. It has been a good place for the few wines I cellar. But what besides storage could have flattened a once fruity cabernet sauvignon? It is/was a 2004 Silver Oak Alexander Valley cab purchased in 2008 and stuck in the crawl space. It had been SO's usual up-front style with, as I recall, a pleasantly long finish. Drank a bottle last night with some grilled steak and found it flat--no tannins, no berryish flavors, no finish. The only thing I can imagine going wrong is my storage place. Anyone with more knowledge of such things have an idea as to what might have happened? TIA.
