Origin & History
Kefir is a probiotic-rich, fermented beverage produced by culturing milk or plant-based alternatives with kefir grains, a symbiotic combination of bacteria and yeast. Originating in the Caucasus Mountains, it is renowned for its tangy flavor and creamy texture. Kefir serves as a potent functional food for enhancing gut health and overall systemic wellness.
“Kefir has been consumed for centuries in the Caucasus region, where it was revered as a "gift from the gods" for its healing properties. Traditionally, kefir grains were passed down through generations and used to ferment milk in goat or sheep skin bags. It remains a staple in many cultures, embodying a rich history of traditional wellness.”Traditional Medicine
