Water Kefir is a healthy, fermented, probiotic sparkling beverage. Very tasty and refreshing on a hot day or any time of year! My grains are beautiful, super healthy and very active. The grains will last forever if you take good care of them, which in turn will reward you with an abundance of water kefir. It takes only a few days to complete the process from beginning to end. The photo of the finished beverage shown was made with fresh ginger and mango. The flavors you can create are endless. CHECK YOUR JUNK MAIL for my reply if you message me.
