The Bittercube Variety Pack provides a must-have assortment of flavors, much like a spice rack. Bittercube uses no pre-made extracts or flavors of any kind. Only real roots, barks, fruits, flowers, spices and herbs are used to create these concentrated, flavorful bitters. A dropper of bitters adds depth and complexity to cocktails, tea, coffee and seltzer. Bittercube Bitters also enhance vinaigrettes, marinades and baked goods.
