Homemade Kefir Is Tangy, Creamy, And Absolutely Worth It (2024)

-Cover jar with something breathable, like a tightly woven cloth or coffee filter, and secure with a rubber band. The kefir grains don't need oxygen to survive but there are bacteria strains within milk and kefir grains that thrive in oxygen-rich environments, so airflow is key.

-Let the jar with the kefir grains and milk sit at room temperature for approximately 24 hours. If it’s hotter where you live, the fermentation process will probably be quicker, or slower if it's cold. You’ll know the kefir is done when the consistency has thickened, the milk tastes sour, and slight swirls of white and yellow start to appear in the mixture—this is the curds and whey just beginning to separate.

Step 2: Strain your kefir

-Pour the mixture through a strainer, catching the liquid in a bowl, and use a wooden spoon to push the grains against the strainer and catch all the excess liquid. You’ll be left with just the grains in the strainer, which will look less like yogurt and more like cottage cheese.

-Pour the kefir from the bowl into another glass jar or bottle and cover with a lid. You can drink it immediately or keep it in the fridge for up to three weeks.

Step 3: Feed your kefir grains again

-Return the kefir grains from the strainer back into their jar and pour fresh milk over them again, then cover and repeat the whole process. Kefir grains will double in size every two weeks or so, so make sure to add more milk to maintain the 1:1 ratio. If you have too many grains, give some to a friend or mix them into a smoothie.

Step 4: Eat or drink your kefir

-Usually, the easiest thing to make myself for breakfast is a smoothie packed with greens, berries, and about a cup of kefir for a tangy kick. If I have extra time on Sundays, I meal prep overnight oats for the week, subbing the milk and yogurt with kefir. But if I’m short on time, I just use kefir as a substitute for yogurt in recipes like Rick Martinez’s caramelized plantain parfait.

Kefir is sort of an acquired taste and newbies will probably shy away from drinking it straight. But by now, I’ve grown to love it. Sometimes I mix in a bit of honey and drink it slowly, enjoying each zingy sip.
