Absolutely. There are plenty of links & methods all over google, but it is fairly simple. I bought some kefir grains off of amazon, which is basically a starter kit to grow. There are ways to make it from Greek yogurt, but I use the grains. I fill a mason jar full of organic 2% milk (doesn't really matter on fat content), rubber and a coffee filter over the top of it. Let it sit at room temperature, preferably in a darker place, for about 2-3 days. The milk will start to become thicker & that's your indication to drain. Strain the milk into a container. I use rubber cap spreader to help strain. But your end result is kefir milk, & the grains actually grow more each time you make more. You can either use those to use more mason jars or what I do sometimes is take the excess grains & blend them up in my shakes. The grains themselves almost look like small cauliflower. Some may think its a difficult process, but it is well worth it once you get going & get used to it. Your gut will surely appreciate it. lol
