Concocting beer cocktails is kind of like creating DJ music. Not only are you setting the pace and flow of your guests' night, but you're also mashing up and integrating disparate elements into a cohesive whole. Mixing beer with liquor isn't an easy task. The bartender must understand the flavor profile of the beer and how it might provide compliment or contrast to spirits and additives. Creating a harmonious union of flavors is a process of trial and error (“reeeeeeeemix!”), and many people erroneously default to simply using beer as filler in a cocktail. When it comes to shaking up beer and booze, we've come to trust Jasper's Corner Tap Bartender (read: “Mixmaster”) Kevin Diedrich.
