What is Kefir?Kefir is a tart and tangy, creamy cultured milk smoothie that contains live and active probiotic cultures and is high in protein, calcium and vitamin D. Refreshing and effervescent, it has been popular in Eastern Europe for more than 2000 years. The Champagne of DairyKefir is called "the Champagne of Dairy" due to its slightly effervescent, fizzy nature. This is a result of natural fermentation—a sign that the kefir cultures are live and active! Don't worry if the bottle is slightly bloated—it's completely normal. Just be sure to shake the bottle well before opening. Making Kefir Since 1986With an Old World culinary spirit burning bright, we crafted the first batches of our Original Kefir in the basement of our family's Skokie, Illinois home in 1986. Today, due in no small part to our Eastern European entrepreneurial spirit, we produce more than 100 varieties of kefir and distribute throughout the US, Canada and the UK. We're proud to be living the American Dream and sharing the wonders of kefir with a new nation of fans.From the Smolyansky Family to yours, drink up and enjoy! Made with Renewable Energy
