When Ben Schiller, head bartender for Chicago's BOKA, wanted applewood-smoked bourbon, he broke out the big guns. "I have a hand held culinary smoker," he said, recounting the steps in one of his signature cocktails, the Smoking Jack. "I smoke the bourbon with applewood, cherrywood, and hickory."

A master mixologist with a background in wine, Schiller has developed a following for precisely this meticulous, exploratory approach to cocktails: "As I’ve turned my focus from wine to spirits, I’ve been exposed to a wider variety of styles and flavors in each spirit category.  I’ve been able to find the expressions of each spirit that I truly love."
