The Allegheny is an attractive drink that Dale found in The Ultimate A-to-Z Bar Guide by Ron and Sharon Tyler Herbst. I looked through several of my own books old and new and did not find it so I am guessing that it is their own original creation, consisting of Bourbon, dry vermouth, blackberry brandy, and lemon juice.

The Allegheny is a mild-flavored drink that according to Dale can be enhanced by muddling in a piece of lemon
