As I mentioned in the "starter kit" thread, I did not like Chivas Regal 12 year, but I do like Famous Grouse. John listed four of the malts that comprise Famous Grouse; now I'm wondering which malts comprise Chivas Regal. Perhaps that information would be useful in identifying malts to avoid, just as the Famous Grouse info serves the opposite purpose.
Is information about the composition of blends readily available, or does it come from participation in insiders' forums?
Oh, and one more thing, how susceptible to oxidation is an unsealed bottle of scotch, as compared to bourbon? I opened the Chivas Regal between six and 12 months ago to serve to guests. (I tasted it for the first time a few days ago.) Could that have influenced its flavor noticeably?
