Has anyone tried this? I made a tea using a bag of Twinnings four red fruits and another of strawberry mango infusion in 16 oz. of water and added 1 tsp. of brown sugar. Then I let it cool, put it in a 16 oz. soda bottle and put about one 16th of a teaspoon of bread yeast. I let it carbonate for two days. It tasted quite good, like club soda with a hint of fruity and yeasty flavors.
