Scotch
This was prompted by the 'Cigars' thread.
I was practically raised on scotch - and often enjoy a decent blend (yes there is such a thing) or a good single malt.
I can't drink more than two at a time though, and usually stop after one. The enjoyment seems to fade after too many.
I'll bet there are a number of scotch drinkers here? What are your favorite blends, and singles?
