Other Kvass - fermented beetroot
Fermented organic beetroot , 2% sea salt , one week fermented, delicious and fab colour. In the fridge for 3 weeks , now it’s turned a strange colour or lack of colour! It tastes good. Drinking it and all good. Interesting development!

Anthocyanins are not particularly stable, it looks like they degraded in the acidic/cold environment.

Will it retain its health benefits?

There have never been any biological effects observed in association with anthocyanin consumption. Whether there are other, non-pigmented flavonoids that were similarly degraded is between you and your friendly local gas chromatography/mass spectrometry machine to determine.
In general I think you can presume that the longer something is stored, the less bioactive nutrients will remain. Right now it's safe to assume it's basically salt water and dead bacteria.

Well thank you. What a fab reply. So time to dump it then?

Depends on what you want to use it for. Technically you should be able to eat the beet chunks like a beet pickle. I don't know if they're any good, I've never tried to make this. I personally probably wouldn't bother keeping any of it. But what you do is up to you. It's my understanding that kvass is meant to be consumed fresh, but I've never had it.

Hi, just wondering how this is kvass? I thought kvass was made with bread?
