Re: Elijah Craig 18year old
Don't compare 'em -- completely different whiskeys, minus the name semblance.
The 18yo is an 'acquired taste' which, interestingly, seems to resonate with Scotch drinkers. Less so with bourbon drinkers, though some like it. Keep in mind that the age is often greater than that stated on the bottle -- and it displays a great deal of wood influence (sometimes the point of being 'cardboard'-ish).
Personally, I don't care for it, in the several iterations I've assayed. Being a single-barrel, batches vary, but I've yet to find one which didn't seem over-aged.
