If you enjoy whisky, then you'll prolly like Cognac too.
While im definitely a whisky guy, I can never turn down a pour of some good cognac or brandy, especially the former. Both are generally sweeter than whiskies. Some people swear than a good cognac will always be smoother than a good whisky/scotch, but im pretty sure those people havent tried top shelf whiskies/scotch. Oh and all cognac's are made from grapes.
