Live Milk Kefir Grains – Grown in Raw Organic Milk

Bring a little traditional fermentation into your kitchen with our live milk kefir grains, grown exclusively in raw organic milk. Lovingly nurtured and picked and packed to order, these reusable cultures are a starting point for making your own creamy, tangy milk kefir at home.

What makes these grains different?

These grains have been grown exclusively in raw milk, so they are conditioned to that growing routine. Choose this culture if you are looking specifically for milk kefir grains raised in raw milk, rather than our standard milk kefir grains.

Raw, goat’s or premium milk kefir grains: which should I choose?

The key difference between these options is the milk we grow them in. Choose according to the milk you plan to brew with and the growing routine you prefer, rather than treating the names as a ranking of quality.

• Premium milk kefir grains: our standard live milk kefir grains, grown in organic cow’s milk. A starting point for everyday homemade milk kefir.
• Raw-milk-grown kefir grains: the grains on this page, grown exclusively in raw organic cow’s milk. Choose these if you specifically want a culture raised in raw milk.
• Goat’s-milk-grown kefir grains: our goat’s milk kefir grains are grown in goat’s milk, so they are already used to that milk before reaching your kitchen.

All three are live milk kefir cultures that need ongoing care. If you want to switch the milk you use, ask us for guidance. Growing milk alone is not a promise of a particular finished flavour or thickness, and these names do not mean one option has been shown to offer greater health benefits.

Choose your starting size

• 5g: a starting guide for approximately 250ml of milk per brew.
• 10g (2 × 5g): a starting guide for approximately 500ml of milk per brew.

These amounts are guides rather than fixed yields. Results depend on your brewing conditions and how settled your grains are. Follow the supplied instructions and give your living culture time to adjust to its new home.

Grown with care, made with love

We grow these cultures in Soil Association-certified organic raw milk from Hook and Son Dairy, produced by grass-fed Holstein Friesian cows. We care for our grains with daily pH checks and pick and pack them to order.

• Live, reusable milk kefir grains.
• Food-grade, heat-sealed packaging.
• Printed brewing instructions included.
• Access to online instructions and tutorial videos.
• Friendly help as you get to know your brew.

Caring for your milk kefir grains

With ongoing care, your grains can be used for batch after batch of homemade kefir. These are dairy-grown cultures. If you want to change the milk you use, particularly to a plant-based alternative, ask us for guidance first rather than assuming the same care routine will work.
