What is Kefir?Kefir is a tart and tangy, creamy cultured milk, has been popular in Eastern Europe for over 2000 years. It contains live and active probiotic cultures that may help support immunity and healthy digestion. Kefir is also high in protein, calcium and vitamin D. The Champagne of DairyKefir is called "the Champagne of Dairy" due to its slightly effervescent and fizzy qualities. These are the results of natural fermentation and are a sign that the kefir cultures are live and active.
