and Drug Administration can ban caffeinated alcoholic beverages such as Four Loko, but it cannot stop bartenders from mixing Red Bull with vodka, coffee with Irish whiskey, or cola with rum. Fortunately, Iowa state Sen. Brian Schoenjahn (D-Arlington) has proposed a bill that would close this dangerous gap by making it a misdemeanor for any business with a liquor license to "manufacture for sale, sell, offer or keep for sale, import, distribute, transport, or possess any caffeinated alcoholic beverage." The bill defines "caffeinated alcoholic beverage" as "any beverage containing more than one-half of one percent of alcohol by volume, including alcoholic liquor, wine, and beer, to which caffeine is added." Hence it apparently applies not only to drinks with a noticeable caffeine kick but also to coffee-flavored liqueurs with detectable amounts of the stimulant, such as Kahlua or Tia Maria, and any cocktails made with them, such as a Black Russian or a Mudslide. In addition to jail time and fines, violators would face revocation (not just suspension) of their liquor licenses, and therefore loss of their livelihoods—a pretty harsh penalty for following the instructions in a Mr. Boston book.
Correction: I put the wrong letter after Schoenjahn's name in my initial post. He is a Democrat.
