The History of Kefir
Origins
Kefir is believed to have been discovered over 2,000 years ago in the Caucasus region. The word "kefir" is derived from the Turkish word "keyif," meaning "feeling good," reflecting the drink's reputation for promoting health. According to local legends, kefir grains were considered a divine gift, and their preparation was kept a closely guarded secret among the people of the Caucasus.
Spread to the Rest of the World
For centuries, kefir remained confined to the Caucasus. In the early 20th century, its popularity began to spread when Russian scientists studied its health benefits. Nobel laureate Élie Metchnikoff, a pioneer in microbiology, highlighted kefir's role in promoting gut health and longevity. This scientific recognition helped kefir gain acceptance in Europe and beyond, turning it into a globally cherished superfood.
