Lifeway Origin: The Lifeway story began with a real belief in the American Dream. In 1986, our family made the first batches of Lifeway Kefir at our home in Skokie, Illinois - just 10 years after we came to the United States from our native Russia. The luscious taste of kefir, long enjoyed in Europe, caught on quickly in Chicago - our early recipes of the probiotic yogurt-like drink got rave reviews in local supermarkets. We've come a long way from the early days of our original plain kefir, to more than 100 varieties enjoyed today. As you'll soon see, it's as delicious as it is healthful. So from our family to yours, drink up and enjoy! Sincerely, The Smolyansky Family, Traded on NASDAQ: LWAY. Kefir History: Kefir is the cousin of yogurt and its roots can trace back more than 2000 years. Originating in the Caucasus Mountains of Europe where people live well past 100 years, the word kefir is thought to have been derived from the Turkish word Keif for good feeling, probably due to the sense of well-being experienced after drinking it.
