Would that be like this water kefir stuff I’ve heard about?
No that's different. That's a pro biotic. The ginger ale or ginger beer as some call it is simply a soft drink like the ginger ale soda but much better. The ginger bug is simply a good bacteria the digests the sugar and produces effervescence. You can adjust the amount of ginger to taste. The more you put in the more spicy bite it has. It takes very little ginger. I also grew my own ginger this year and will continue that. We love the pickled ginger also.
