Kefir fermented milk drink

Kefir is a fermented milk drink with origins tracing back centuries to the North Caucasus region, located at the intersection of Eastern Europe and Western Asia. It is traditionally made by inoculating cow, goat, or sheep milk with kefir grains, which are cultures of bacteria and yeast. In modern commerce, kefir is produced globally by various dairy companies ranging from small artisanal farms to large multinational corporations.

Because 'Kefir' is a generic product category rather than a single trademarked brand, its manufacturing and ownership vary significantly depending on the specific brand purchased. Major commercial producers include Lifeway Foods in the United States, Danone in Europe, and various local dairy cooperatives across the Middle East and Central Asia. The product is widely celebrated for its probiotic properties and nutritional benefits.
