What is kefir?

Kefir is a fermented milk drink made from cow, goat, or sheep milk, containing a mix of beneficial bacteria and yeasts. It is produced by adding kefir grains, which are cultures of lactic acid bacteria and yeast, to the milk, allowing it to ferment for about 24 hours. The resulting beverage is tangy, slightly effervescent, and rich in probiotics, making it popular for its potential health benefits, including improved digestion and gut health. Kefir can also be made with non-dairy alternatives, such as coconut or almond milk.
