What’s in the bottle

  • Goat’s milk and live kefir cultures — nothing else
  • Naturally fermented and lightly effervescent, with no added sugar or flavours
  • A 250 mL glass a day: four serves per bottle
  • Made in small batches in Hopetoun Park, Victoria, and kept cold from our fridge to yours

How to enjoy it

Shake gently and pour. Have a glass on its own, over muesli or in a smoothie. Natural separation is normal — a shake brings it back together. Keep it refrigerated at or below 4°C and use it within 7 days of opening.

Kefir is a living food. Flavour and fizz shift a little from batch to batch, and the bottle may bulge slightly as the culture keeps working in the fridge. Open it over the sink the first time.

Subscribe monthly and never run out

Subscriptions come as six-packs: six 1 litre bottles delivered chilled once a month for A$178.25, which is 15% off the A$34.95 single-bottle price, plus A$15 packaging and postage per delivery. Add a vitamin C six-pack to the same monthly delivery if you like. You can pause, skip a month, change your card or cancel whenever you like from the My Orders page, which opens your secure Stripe customer portal. No account to set up and no password to remember: Stripe emails you a one-time login link.

What the research says

Many of our kefir customers take it alongside our Liposomal Vitamin C, so we have published a plain-English, fully referenced summary of the peer-reviewed vitamin C research, including the liposomal absorption trial and an honest account of the high-dose intravenous studies and what they do and do not show.

Kefir is a food, not a treatment for any disease. Always consult a qualified health care professional before taking any supplement or making changes to your diet for health reasons.

Delivery and collection

Kefir travels chilled. We deliver across Melbourne metro, and you are welcome to collect from Hopetoun Park by arrangement. Interstate delivery is not available for kefir because it needs to stay cold the whole way.

Pairs well with Liposomal Vitamin C

A teaspoon in your morning glass of kefir is the easiest daily habit there is. Both come in the same 1 litre bottle, on the same monthly subscription.
