About 6 months ago I decanted a decanter of Old Crow 10yo from the chess piece it was originally packaged in to a crystal decanter (please hold the health concerns of storing whiskey in lead-crystal.) Anyway, when I first opened the original container the bourbon had a corky-mustiness and the generally unpleasant taste of a whiskey stored for a long time in porcelain. I tasted it quite a bit early on after decanting and it seemed much the same as when I first opened it. Well tonight, wanting something different, I went back to the crystal decanted Old Crow for the first time in about 5 months. I must say that the objectionable taste is gone almost completely and the bourbon is very clear and bright on the palate. It tastes like you might expect a 10yo Old Crow from the 60s stored in glass to taste.
So my question is: Does anyone else have experience with decanting a porcelain decanter into crystal or glass and having the bourbon improve over its condition when first opened?
