While researching and reading about the plethora of cocktails that have been devised over the last 200+ years, I came to appreciate the enormous diversity within the realm of mixology. Yet at the same time, I also began to realize that the lineages of a number of them could often be traced back to classics, or corresponding variations on a respective theme. Clearly there are many drinks in existence today which are novel creations, often times a bit more complex than earlier-dated cocktails which might display subtle hints of their origin. The vast array of commercially available spirits, liqueurs, and bitters, combined with the unknown number of craft and housemade infused spirits, syrups, and sweeteners are seemingly limited only by the imagination. In my recent inaugural efforts to create original cocktails, I started with ingredients and ratios with which I had the most experience, and began my venture from there. Although the resulting concoctions were not offensive to myself or the immediately available guinea pigs at my disposal, the world of mixology can be a rather personal one...with slightly altered proportions, different classes of spirits, or distinct ingredients altogether resulting in the thumbs up or down from fellow imbibers. That being said, in a humble effort to sift through and simplify what is an incredibly profound universe of cocktail recipes, I have decided to take a look at how some of the most common and well-known were originated, evolved, and/or remained the same over time. Lacking a more innovative approach myself, I decided to model this project on reference material ('The Classic 25 Drinks Every Bartender Should Know') used during my BarSmarts certification. With the minds of Dale DeGroff, Doug Frost, Steve Olson, F. Paul Pacult, Andy Seymour and David Wondrich at the helm of such an educational effort, I figured I certainly couldn't go wrong, let alone come up with a better approach. So with that, I'll take a look at the first of my 20 quintessential cocktails (XXQC)...the Old Fashioned.
