I want to make my fermented water kefir drink more fizzy. I used to following recipe
1st Fermentation 24h
237ml hot water
1.2 l room temp filtered water
2nd Fermentation 48h
51ml Lemon Juice
1l Kefir water from 1st Fermentation
5g sugar for each 0.33 l bottle
I used these fermentation lids which lets oxygen out but no in. after the second fermentation the the drink is as flat as ironing board. How can I make the drink more carbonated?
After the second try, I did use just the flip-top bottles and closed the bottle tight. I opened the lids once a day since I was afraid of an explosion. Opening the bottle might have reduced the carbonation. It is adequate but could be a little more. Nevertheless, safety first.
From my experience, close the lid tight and leave it outside for about 24-48h. Leave it closed at your own risk.
