My kefir or kombucha is not fizzy. Is it safe to drink?

Absolutely. The fizz is a by-product of the fermentation process but is not necessary for the healthy benefits. You may find the drink gets fizzier the closer the kefir or kombucha gets to its best before date, as it has had more time to ferment. Some of our customers prefer it to be fizzy, while others prefer no fizz. If you would like to increase the fizz, you can try leaving it out on the bench for the day to speed up the fermentation process. If you would like to get rid of the fizz, you can release the cap often until the fizz diminishes.
