What is water kefir?

Water Kefir is a fermented, naturally carbonated, probiotic beverage made with kefir grains called tibicos (probiotics), sugar, water & yeast. Herbs, botanicals, and fruit essences are use to create our lightly flavored sparkling creations!

Is it natural?

Yes! The entire fermentation process is 100% natural, utilizing traditional fermentation methods. We use all of the freshest ingredients, organic where we can, to create an intentionally sourced, naturally made drink!

Is it healthy?

Known as an ancient longevity elixir, it most definitely is! Our water Kefir beverages contain 100 calories per can, 0 sugar and no artificial sweeteners, 100% naturally occurring enzymes, probiotics, vitamins, minerals, and antioxidants that help replenish our gut’s biome, which aids in metabolism and strengthens our immune system.

Where is it made?

Our Water Kefir is handmade, batch by batch, by our incredible team of magical souls here in our beautiful brewery on the eastside of downtown San Antonio!
