So I got the boy his own soda making kit (Old Fashioned Homebrew Soda brand) at the homebrew supply, came with the 2oz cherry extract and a champagne yeast. Mixed it with the 4 gal of water sugar and added the yeast starter (whole packet) . Followed all the directions, bottled let sit for a few days then moved to a dark storage container for about 1 1/2 weeks. Tried the first few bottles and everyone says it tastes like cold medicine at the aftertaste, and sure enough it does. Now my question would be why, going on 4 weeks now and chill a bottle and open taste and still medicine taste. Any ideas, would like to get another mix and try again but don't know now.
