Welcome to the simple and rewarding process of fermenting milk with kefir grains. Caring for kefir grains is a bit like caring for a pet—they need regular attention and care, and in return they help create a nourishing, probiotic-rich drink.
We have been using milk kefir in our home for over 8 years and value its benefits for gut health. It has become a daily staple in our family, with our children growing up drinking it regularly.
This guide is available as a printed booklet (A5 format, stapled, and printed in-house) or as a downloadable PDF. If you choose the email version, please check your inbox for an email with the subject line: [KoruKai Herb Farm] Files available for your order.
The guide includes 16 pages of clear instructions, tips, and recipes to help you confidently make and maintain your own milk kefir at home.
