Starter cultures for kefir and kombucha

[RichterScale7]

Please can someone recommend reliable UK supplier for either / both? Thank you.

I got mine off eBay. Worked fine.

I got my keifer grains from 'freshly fermented'. They are excellent.

Check Facebook and nextdoor there's often some listen ( in my area so I presume others too)

If you are in S/W Yorkshire I might be able to give you some Kefir grains.
