Bittercube was founded by Nicholas Kosevich and Ira Koplowitz in 2009. After successful stints at Town Talk Diner (Nick) in Minneapolis and The Violet Hour (Ira) in Chicago, they began developing, formulating, and tweaking the lineup that became the six original varieties of Bittercube Bitters. The first larger batches began maceration in July of 2010; since then, the bitters lineup has expanded to eight year-round varieties and the business has grown to be distributed in more than 25 states around the country. Beyond bitters, Bittercube consults with a number of restaurants and bars, creating unique cocktail programs throughout the country. Bittercube has a team of dedicated cocktail craftsmen and lend its spirited prowess to trade shows, cocktail classes, events, weddings and cocktail dinners. Bittercube has been featured in Martha Stewart’s Everyday Food, Playboy, Imbibe Magazine, Timeout, Chicago Tribune, New York Times, Bloomberg BusinessWeek, GO – AirTran Inflight Magazine, Milwaukee Journal-Sentinel, NPR, and Daily Candy, among other publications.
