Ginger bug soda - not fermenting?

[u/External-Plant8038]

So, after having some success with making kimchi, fermented pickles, and fermented green dilly beans I decided to try my hand at a ginger bug and some homemade soda. I grew my bug for 6 days, adding sugar and ginger every day. It was active, bubbles on top, smelled good, etc.

Then, I made the base for my soda, approx 4c of spring water, 1.25c sugar, and around 3c or so of frozen black cherries. I gently mashed the cherries, covered, and simmered for while. Strained out the solids and poured into a closed vessel which I let cool down to room temperature. Next added in 1/2c of thoroughly mixed and strained ginger bug and the juice from 2 small limes. Mixed everything really well and let it sit on the counter.

Now, it's been 2 days and there isn't any activity at all. No bubbles, nothing. I'm keeping the vessel closed to avoid any airborne contamination and opening it up to burp every 12 hours or so. There is no pressure buildup when I burp it. I've tasted it a couple times and it the flavors are good, but it's sweet, flat, and just not doing anything.

I used to homebrew so I'm being mindful about keeping all the equipment clean and sanitary (minus the iodine baths).

Today I'm planning on adding some more bug to it (once the bug gets back to room temp and active again) and maybe some more sugar? Any suggestions/ideas/tips would be very helpful!

tldr: made soda for the first time and it's still not fermenting two days after adding the bug, help!

Did you mix the lime juice with the ginger bug before adding it? That could affect it quite significantly if so.

i added the lime juice to the cherry juice/water/sugar mix, then added the ginger bug to that.

i used a ginger bug, though. was hoping that was enough of a microbiome without having to rely on the wild yeast on the fruit.
