More info on Kefir:
Milk kefir comes from the Caucasus, a mountainous region where the European continent meets Asia. It’s here that milk kefir earned its reputation as an elixir of long life and a medicinal tonic.
Milk kefir grains are a gelatinous mass harboring a generous variety of bacteria and yeast. They are used to make continual batches of milk kefir. There’s no actual grain in kefir grains. They are called grains because they are small and numerous, like grains of sand.
Kefir is closely related to cultures found in raw milk.

When kefir grains are added to milk, the bacteria begin feasting on the lactose in the milk. The lactose nourishes the grains, allowing them to grow and reproduce.

The grains are so strong and growing so fast, I cannot believe. I'm very happy with my kefir grains. Thank you so much for selling them. If for any reason I need to buy again, I will buy it from you.

Great for Lambs too

I have been making Kefir for about six months now and have been very happy with the grains sent (safely) to us. It is easy to make and we use it with our porridge in the morning and making smoothies - yum! It's refreshing on i'ts own too! Interestingly we are currently hand rearing a number of lambs to which we are feeding Kefir. We have had no cases of scours and bloat to date. We would recommend incorporating Kefir into the milk mix for all young animals being hand reared.

Great service!

Just wanted to say thanks so much for the milk grains and the thorough instructions that come with it. I’ve made two batches of kefir now and they’ve turned out great! I read about kefir and it’s benefits in a book called the Good Skin Solution by Shann Nix so I was happy to find somewhere that provided these grains in NZ! You provide such an amazing quick service too which was great as I was excited to get started.
