I’ve have been making kombucha for a couple of years now and had loads of really successful batches, I haven’t changed anything to my process but the last two batches haven’t gotten fizzy and I can’t work out why.
I don’t think it is because of the temperature as the first non-fizzy batch was made in September when it was still warm outside and I’ve made successful batches in the winter before.
My process for F1 is:
750ml boiled water
2.25l dechlorinated water
3 tea bags
1 large scoby
300ml starter liquid
200-300g of sugar
Leave to ferment for 10 days
F2:
Put some of the fermented tea back in the scoby hotel
Bottle in clean glass bottles
Add flavours
Add a bit more sugar
Leave to ferment for 5 days
They taste more like syrup now because the sugar hasn’t fermented properly.
The only thing I can think of is that there was a few month period where I didn’t feed the scoby hotel, however it’s been fed 3 times since then and is still growing scobys so appears to be healthy.
Does anyone have any guidance on how to revive a scoby hotel differently to what I am already doing?
Or know what I might be doing wrong?
