In this wonderfully prepared blog, you get a chance to follow Jay Hepburn as he navigates the often confusing world of mixology. He caught the cocktail bug, and is ardently documenting his adventure.
Jay unfortunately got away from the whole cocktail scene for many years, and during that time he accidently let his domain expire. Until such a time that he can get it back, or start it up somewhere else, I am linking to what appears to be "the most recent" version of his site from the Internet Archive.
One of my favorite parts of his site, was the detailed examination and explanation he did of orange liqueurs. Since the "search" option doesn't work on the internet-archive version, here is a link that will help: Orange Liqueur Showdown.
