What is kefir?

Kefir is a type of fermented dairy product that has a slightly tangy and effervescent taste. It is typically made by adding a combination of bacteria and yeast cultures, known as kefir grains, to milk. The kefir grains ferment the lactose in the milk, converting it into lactic acid and producing a thick, creamy texture. Kefir is known for its probiotic properties and has been linked to a range of health benefits, including improved digestion and a strengthened immune system. Kefir can also be made with non-dairy milks, such as soy or coconut milk, for those who are lactose intolerant or follow a vegan diet.
