Kefir is an acidic fermented milk beverage that originated from the Caucasus region, thousands of years ago. It is produced from kefir grains, which are a cluster of active microorganisms (bacteria and yeasts) held together in a white gelatinous matrix that look like small cauliflowers. Kefir has a uniform creamy consistence, it is slightly carbonated and it presents a small amount of alcohol, produced by the yeasts.

Kefir is actually considered an example of probiotic mixture of bacteria and yeasts. Today, traditional authentic kefir can be prepared by culturing pasteurized milk with kefir starters at home. The main species of bacteria found in kefir belong to the genera of Lactococcus, Lactobacillus, Leuconostoc and Acetobacter, while yeasts are mainly Kluyveromyces marxianus and Saccharomyces cerevisiae.
