I am brewing ginger beer for the first time ever. In fact this is the first time I am brewing ever. I used 200 grams of sugar, 100 grams of yeast, a few mint leaves, and a whole lemon (sliced) in 1.5 liters of water and boiled the mixture. Then cooled it and added 1 teaspoon of baker’s yeast, squeezed one lemon in it and put it in an airtight bottle with an airlock. I cleaned all article with hot water prior to use. 7 days down the line, I opened the bottle and found that the brew to be sour in taste (it does smell of alcohol). Is it possible that there is vinegar in the brew? Is there any test to find out if there is vinegar in the brew pls.?
Looking forward to your advice.
Thanks and Regards,
