I make fermented fizzy enzyme drinks at home all the time, no soft drinks anymore. It has to be all the time as it is a perpetual drink. You buy on of those fancy hipster live enzyme drinks, but you never finish it. Just and juice, sugar, jam - whatever what bacteria like and it continues fermentation. At room temperature. Every two days it is ready again, drink it, feed it. If it is too active, put it in a fridge. I try to spread it as people have forgotten this.
