Bittercube was founded by Nicholas Kosevich and Ira Koplowitz in Madison, in 2009. Nick and Ira began developing bitters before Bittercube was formed and brought their ideas, techniques and recipes together. For nearly a year, the duo formulated, tweaked and refined their recipes and the large lineup of Bittercube Bitters was born. They also came up with some bar accessories. Bittercube Bitters are developed in Milwaukee, WI and created in Madison, WI, using spirits from Yahara Bay Distillers, where all aspects of production are completed.
