Kefir is a fermented milk drink made by adding live kefir grains to fresh milk and leaving it to ferment for 24 hours. The result is a creamy, slightly tangy drink containing over 50 strains of live bacteria and yeasts, significantly more diverse than yogurt or any commercial probiotic supplement. Kefir originated in the Caucasus mountains over 2,000 years ago and is now one of the most researched fermented foods in the world, with documented benefits for digestive health, immune function and lactose intolerance. At NutriBrew we supply fresh live kefir grains shipped in their active state, ready to ferment from day one. Find out exactly what kefir is and how it works.

Frequently Asked Questions About Kefir
What is the difference between kefir grains and kefir from the supermarket?
Supermarket kefir is pasteurised after fermentation, which kills the majority of live cultures. Kefir made at home with fresh live grains contains between 10 and 25 times more active bacteria and yeasts, with no additives, no preservatives and full control over the fermentation process. Live grains also reproduce with every batch, meaning one purchase lasts indefinitely.
What are the benefits of drinking kefir?
Kefir supports digestive health, strengthens the immune system and reduces symptoms of lactose intolerance. It is one of the most researched fermented foods in the world, with documented benefits for gut microbiota diversity, inflammation reduction and nutrient absorption. Regular consumption of kefir made with live grains delivers billions of active cultures in every glass.
Is kefir better than yogurt?
Yes, in terms of probiotic diversity. Yogurt typically contains 2 to 4 bacterial strains, while kefir made with live grains contains over 50 strains of bacteria and yeasts. Kefir also contains yeasts in addition to bacteria, which yogurt does not, making it significantly more complex and beneficial for gut health.
Can I buy kefir in Irish supermarkets?
Yes, supermarket kefir is available in Ireland but it is pasteurised after fermentation, which significantly reduces the live culture count. Kefir made at home with fresh live grains contains between 10 and 25 times more active cultures than supermarket versions, with no additives, no preservatives and full control over the fermentation process.
How do I make kefir at home in Ireland?
Making kefir at home takes less than 5 minutes a day. Add fresh live kefir grains to whole milk, leave at room temperature for 24 hours, strain the grains out and your kefir is ready to drink. The grains go back into fresh milk and the process repeats indefinitely. NutriBrew ships fresh active kefir grains nationwide across Ireland with next day delivery.
