I was reading an article on whisky blending not too long ago, and they mentioned the interesting tidbit of information that "grain spirit" (of the sort they use for making blended Scotch) tends to age and peak much more quickly than the low distillation proof single malts it's blended with.

Seeing as every so often people seem to mention how the distillation proofs on modern bourbon have been creeping higher and higher, along with people claiming that more than 10 years in the barrel tend to make a woody bourbon, I sorta put two and two together... However not being quite so knowlegable on the subject, I thought I'd ask the people around here.

Do you fellows think that the reason bourbon doesn't seem to age so well is because of the higher distillation proofs they use nowadays??
