Bittercube Bitters are created in Milwaukee, WI, by hand with real botanicals. No pre-made extracts or flavors are used in our slow-crafted products. The maceration process is unique to each style and batches take as long as twenty-five days to complete. The company has grown from producing one gallon jars of bitters in 2009 to 210 gallon batches now, but the process has largely stayed the same. We source botanicals as close to origin as possible and use high-quality base spirits to create densely flavored bitters.
