From the contest entry page:
While crowd-sourcing is typically employed in the pursuit of esoteric and/or trivial projects, like developing new kinds of software or analyzing unwieldy piles of data, there's no reason it can't be used for something truly useful, like inventing a new cocktail. You send in your recipes, we judge them. The winning entry will get a $500 shopping spree at KegWorks.com, along with all the glory that will surely come with giving the world a great new balm to toast its triumphs, ease its setbacks, seal its deals, and enliven its slow days at the office.
The mind races with the possible ingredients that would go into a cocktail called a "Magnificent Bastard".
I might enter. Just wondering what I'd use as the "bastard" to complement the magnificence of the cachaça. Personally, I think that approach will be the key to a win. Boning up on Embury's Fine Art of Mixing Drinks, which MB references, might help as well.
