About Kefirgrains.eu

Welcome to your trusted source for authentic fermentation. We believe that making your own probiotic-rich drinks at home should be easy, accessible, and fun.


Our Passion: Living Cultures

At Kefirgrains.eu, we specialize in the three most popular fermented wellness drinks:

  • Milk Kefir: A creamy, tangy, yogurt-like drink rich in probiotics.
  • Water Kefir: A sparkling, dairy-free alternative similar to a natural soda.
  • Kombucha: A fermented tea known for its unique flavor and health benefits.

What makes these drinks special is that they are made with living cultures—kefir grains and kombucha SCOBYs. These complex symbiotic communities of bacteria and yeast work together to transform simple ingredients like milk or sugared water into powerful, gut-healthy beverages.

Our Story: Finding the Best Grains

When we started our fermentation journey, we quickly realized that not all kefir grains are created equal. We experimented with dozens of different strains from various sources—some were too small and hard to filter, others were weak or inconsistent.

Our goal was to find grains that were robust, easy to handle, and produced a consistently delicious kefir. After extensive testing, we settled on a hardy, medium-to-large grain variety originally sourced from Dom’s Kefir in Australia.

Why we love our grains:

  • They have a resilient cauliflower-like structure.
  • Their medium-large size makes them very easy to filter from the finished drink.
  • They have decades of exposure to high-quality, organic milk, making them extremely strong and active.

We feed our grains daily with fresh, organic milk to ensure they are happy, healthy, and ready to start working for you immediately upon arrival.

Frequently Asked Questions About Our Grains

Are kefir grains everlasting?

Yes! With proper care, your kefir grains can last forever. They are living organisms that grow and multiply with each batch. However, they are not indestructible. They need regular feeding (fresh milk or sugar water) to survive. Exposure to extreme heat, harsh chemicals, antibacterial soaps, or chlorine can kill them. Treat them well, keep their environment clean, and they will provide you with a lifetime of healthy drinks.

How is kefir different from yogurt?

This is our most common question. The main difference is in the complexity and diversity of the probiotics.

  • Yogurt is typically fermented by just a few strains of bacteria from the Lactobacillus family.
  • Milk Kefir is fermented by a complex community of nearly 60 different types of bacteria and yeasts working together. This makes kefir a much more potent and diverse source of probiotics.

Are all kefir grains the same?

No. Just as every culture has a unique microbial makeup, their physical appearance can also differ. Broadly speaking, grains can be categorized as either “flat-sheet” or “globular” (round).

Some varieties, like certain Turkish grains, tend to be flatter. Others, like many Russian strains (and ours), grow into rounder, cauliflower-like clumps. Some grains remain small, while others can grow quite large if left undisturbed. We prefer the medium-large globular variety for its ease of use.

Should I drink kefir every day?

While kefir offers numerous health benefits, it is a natural food, not a medicine. You don’t have to drink it every single day to benefit from it. Many people drink it daily, while others enjoy it a few times a week or alternate between different fermented drinks like water kefir and kombucha. Listen to your body and find a routine that works for you.
