The time: thousands of years ago
The place: the Caucasus region of Eurasia (see map below)
The people: nomadic tribes
The challenge: bringing milk on long journeys
The solution: carrying the milk in leather pouches
The discovery: the milk did not spoil but thickened and developed a pleasant yeasty tartness

To this day, kefir is a popular cultured dairy beverage in Eastern and Northern Europe.
Nowadays we don't need to carry milk in leather pouches across the vast expanses of Eurasia to enjoy a glass of refreshing homemade kefir.
While homemade kefir is often made with kefir grains, our company, Cutting Edge Cultures, went a step further and developed a starter culture in a powder form made from freeze-dried kefir grains. Just add the Easy Kefir starter to milk and let the mixture ferment for about 24 hours at room temperature.
Once you've made a batch of kefir using our Easy Kefir starter, you can save some of it to culture your next batch. This is called 'reculturing' and can be repeated several times over.
