I’m making my first batch of ginger beer using a ginger bug. I’m using a 16oz plastic test bottle (with 1.5” air at the top) and seven 16oz brown swing top glass bottles (with 2” air at the top— the space is narrower).
After 3.5 days, the test bottle is quite firm, though not rock hard. I can still squeeze it and it has some give. I’ve burped one glass bottle each day as a test (three of them so far), and none has shown any sign of fizzing, etc. I tried a sip of one today (the same bottle I burped on day one), and it had a nice flavor but no carbonation.
It seems like fermentation is happening, since the plastic bottle has become firm. I don’t suspect that the swing top bottles are leaking air, since they‘re new and from a fermentation supplier.
Am I just being impatient, and I should wait longer for them to carbonate?
And should I put them in the fridge now, or give them more time at room temp?
