Yeah, it's in Rothes; I drove past it a bunch of times when we stayed in Craigellachie. There's distilleries everywhere you look in that part of the country (like, literally, go up on a hill and look in any direction), and Glenrothes is one of the better known (there are a bunch of distilleries around there that produce only for blended scotch, but Glenrothes is one of the more popular single malts).

Glenrothes is the first scotch I recommend to anyone who loves bourbon and thinks they hate scotch.
