Where can I find kosher kefir grains? Or does kefir grains not need a certification?

I am interested in making my own kefir drink. I'm in NYC if that helps. Thanks.

  1. It does need certification, and I don't know where you can get it. However, here's a helpful hint: if someone takes any kefir grain and cultures milk with it, then takes the grain from that and cultures some more milk, then does this a third time, the grain from that 3rd culture will be kosher, and can be used to make kosher kefir. Note, however, that you can't deliberately do this; it's only good if it just so happened to have been done (e.g. by a friendly non-Jew).

      Given how kefir is made, wouldn't all kefir sold at this point have been through that process?

        Mostly it depends on whether you consider commercial milk to be chalav yisrael (i.e. kosher). If you don't, then you're starting with non-kosher and it won't be kosher until it's been "laundered" through three generations, and you can't do it yourself on purpose.

    2. Perhaps you can use existing kefir as a starter for your own? This is possible with yoghurt, but I don't know if the two processes are similar enough to do it. There are certainly kosher kefirs on the market to work with.
