Kefir is a lightly tangy, drinkable yoghurt made by fermenting milk with kefir grains—tiny colonies of bacteria and yeast. It’s naturally rich in probiotics, easy to make at home, and versatile. With simple steps, clean jars, and room-temperature fermentation, you’ll brew a gut-friendly staple for smoothies, breakfasts, and daily sips.
What kefir is and why it helps
Kefir is a fermented dairy drink with a thinner texture than yoghurt and a brighter, effervescent tang. The grains (not cereal—living cultures) transform milk’s sugars into acids and mild carbonation, building diverse probiotics. Many people enjoy kefir for everyday gut support, culinary flexibility, and its refreshing, yoghurt-adjacent flavor.
Key highlights
Probiotic punch:
Naturally diverse cultures may support digestive balance and make dairy easier to tolerate for some.
Beginner-friendly:
Minimal equipment: a clean jar, breathable cover, and a nylon strainer. Set-and-sip simplicity.
Versatile in the kitchen:
Use plain, in smoothies, overnight oats, salad dressings, or as a buttermilk swap in baking.
Simple step-by-step: How to make kefir at home
Gather ingredients:
Milk: Whole or low-fat cow’s or goat’s milk; start with 500 ml.
Kefir grains: Active dairy kefir grains.
Prepare the jar:
Clean glass jar (500–750 ml) with a breathable cover (paper towel or cloth + rubber band).
Combine and ferment:
Add grains (1–2 teaspoons) to the jar. Pour in milk, leaving headspace.
Cover and ferment at room temperature (20–24°C) for 18–24 hours, away from direct sun.
Check texture and taste:
When slightly thick, tangy, and lightly bubbly, it’s ready. Longer ferment = more tang.
Strain and store:
Strain with a nylon or plastic strainer (metal can irritate grains).
Refrigerate the kefir for up to 5 days. Return grains to fresh milk to start the next batch.
Flavor (optional):
Second ferment: Add lemon zest, vanilla, or fruit and rest sealed in the fridge 6–12 hours for subtle aromatics.
Tips for smooth brewing
Mind the temperature: Cooler rooms slow fermentation; warmer speeds it up.
Don’t overheat: Never heat grains; they’re living cultures.
Use fresh milk: Consistent results and better flavor.
Cleanliness matters: Rinse equipment well; avoid soaps with residue.
Travel pause: Store grains in fresh milk in the fridge for a few days to slow activity.
