Our Grains have been carefully taken care of. We have obtained our grains from multiple sources over the years. This helps us offer the best possible kefir with as many different bacteria strains possible. They have never been dried or stored in the refrigerator and they are given fresh milk daily to keep them healthy, active and very well balanced. The kefir they produce within 24 hours has a wonderful consistency. They will begin to grow very quickly as you take care of them. You may use any type of milk that is available to you. We recommend whole milk especially during the reactivation process after the shipping time. The absolute best is raw organic cow or goat milk. You will receive whole milk kefir grains and a link to download our comprehensive 29 Page eBook that will teach you all things Kefir. This includes health benefits, instructions with pictures, recipes, tips and tricks to make the best tasting kefir and frequently asked questions. Links to our video tutorial is also included!! The Kefir Grains are sealed in a food grade container that is BPA free (not a sandwich baggie like other providers use). Grains arrive fresh with little to no activation. Email support is included to make sure you have a great kefir experience. Whether it is your first time or starting up again. If anything happens to your grains during transit we will gladly ship you a new batch. Accept only the Best from Fusion Teas!
