The recipe for our cherry cola is based on the recipe of OpenCola, a trademark that is unique in that its recipe is freely available. Anyone can make this drink themselves, as well as modify and improve the recipe, as it is distributed under the GNU General Public License. We removed sugar, caffeine and caramel color from the recipe, replaced orthophosphoric acid with cherry and lemon juice, and used black rowan juice as a coloring agent. Due to this, our cherry cola is not only tasty, but also healthy!
