Water kefir grains are a symbiotic relationship between yeast and bacteria. They are plump, translucent grain-textured bacterial cultures. Water kefir grains are much like a kombucha scoby but water kefir is caffeine free, ready in 48 hours, more pleasant tasting and higher in probiotics. Water kefir grains offer an abundance of different ways to incorporate live probiotics into everyday life. Not only can they be used to make a low sugar soda, but the grains can be used to ferment coconut water and all nut milks. Water kefir grains can also be used to make: sour dough starter, coconut yogurt, salad dressing, gummies, popsicles, smoothies and much more! Package content yields 1/4 cup once hydrated. Happy Gut Pro grains are grown in natural spring water and organic sugars. Our facility is fully licensed and monitored by a microbiologist.
