The kids and I picked some wonderful Florida blueberries a few weeks ago, and this was a perfect project to use up 6 cups of them. I assume you can use any kind of berry/fruit with this recipe, or just make ginger soda with your "bug" (which I have done before).
While you are building your "bug", make sure to cover it with a secured cloth to prevent any contaminants from finding their way in.
Here's my "bug" after only 4 days. The natural yeasts on the ginger root are very active and ready to culture some soda!
For the next part of the soda-making process, you will need:
1 1/2 c unprocessed sugar
1 gallon filtered water
1 cup soda "bug"
glass gallon-sized jar
Here's the fermenting vessel I used for the soda. And, after about 3 days, my vessel looked like this:
When your soda looks this bubbly, you may choose to go ahead and bottle it! If you prefer a less- sweet soda, you can let the fermentation continue for another few days- up to a week.
I chose to bottle mine on day 3. (Before bottling, make sure you filter your soda with a large strainer or colander.) Since I have had homemade soda bottles explode on me before, I am putting mine in the fridge right away. The original recipe called for a second fermentation in the bottles, but I'm a little paranoid about exploding glass. So, I will keep mine in the fridge for another week or so, then I will test the carbonation and go from there! If you choose to leave your bottles on the counter for another 2-3 days, please check the carbonation every 12 to 24 hours so that an accidental explosion is less likely! I would rather be cautious than sorry. :)
Enjoy your homemade, probiotic-rich sodas with family and friends. Feel good about serving a healthy soda to the people you love!
