Speedy

Not just in shipping but also in how quickly these started multiplying. I'm already fermenting 1.5 litres of sugar water every 2 days.

Hi Batina,

Thank you so much for sharing this! I’m really glad to hear the grains arrived quickly and that they’ve taken off so well for you. Multiplying enough to ferment 1.5 litres every couple of days is a fantastic result. It sounds like you’re going to have plenty of delicious kefir on hand!

Enjoy your brewing, and thanks again for your kind feedback.

Warm regards,
Sandy

Easy water kefir

Easy to hydrate and produced a light sparkling kefir within the 48 hours.

Hi Meredith,

Thanks so much for sharing your experience! We’re delighted to hear your grains hydrated easily and gave you a refreshing kefir so quickly. Enjoy experimenting with flavours — that’s where the fun really begins!

Best wishes,
Sandy

Love the refreshing second ferment

I found the instructions very easy to follow and created a tasty refreshing second ferment in just a few days. My husband (who prefers commercial fizzy drinks) liked it too. I can’t wait until summer comes to be enjoying these fermented beauties in hot weather. Highly recommend this product and supplier.

Hi Natalia,

Thank you so much for your lovely feedback! I’m thrilled to hear you’re enjoying the second ferment—it really is such a refreshing alternative to commercial fizzy drinks. I love that your husband enjoyed it too! I agree, nothing beats a chilled glass of water kefir on a hot summer’s day.

I truly appreciate your recommendation and kind words. Happy fermenting!

Warm regards,
Sandy

Milk Kefir Grains

Best gift I have purchased

I purchased the French Sourdough Starter Kit as a gift for my daughter Felicity, and she has absolutely mastered it! The kit was beautifully presented and came with everything she needed to get started. The instructions were clear and easy to follow, and within no time she was baking delicious, crusty sourdough loaves that taste amazing.

It’s been such a joy watching her enthusiasm grow and seeing the wonderful results each week. This kit has truly sparked her love for sourdough baking — a perfect gift for anyone wanting to try something new and rewarding. Highly recommend!

Making great Kefir

Arrived quickly and very much alive, I'm now making fresh Kefir daily! Super happy with the purchase. I've tried powders before, but they weren't as effective as these live grains.

Hi team

We had some questions when the kefir grains arrived and Sandy from the Fermentation Station was super prompt with her responses which helped a lot.
I can recommend The Fermentation Station highly.

Stick with a sharp end

It's a wooden-handled metal stick with a razor on the end. Makes a neat slash in your sourdough. Hooray etc. Comes with spare blades. Came with the Sourdough Master Kit which has mostly useful items, and some less useful clutter (pen, sticky labels).
