We only drink raw organic-fed milk so our kefir grains do too. These are very hardy grains; I tend to neglect them and they still do very well. They will even make kefir in the fridge, which we actually like better as its a smoother product. $5.00/ 2 heaping tablespoons. As we cannot sell raw milk, we ask that you bring a container of your own milk that we can transfer the grains into. We are located in Metchosin (we also have 100% pastured, organic fed eggs available!)
