Hello,
I give Kefir grains in the Val de Marne region (94) on Thiais/Vitry sur Seine, do not hesitate to write to me. I give you the recipe that I personally use at the same time.
No postal delivery.
I have been making kefir for two years and given how the seeds spread, I would be happy to give some ! I live in Talence and I can't go far from my neighborhood.
