Kefir grains are living clusters of bacteria and yeasts that ferment milk; they are not cereal grains. They are a minimally processed starter culture, and you can reuse them to make successive batches of milk kefir.
To make kefir with kefir grains, cover the grains with milk in a clean jar and leave it at room temperature to ferment. Strain the finished kefir and transfer the grains into fresh milk for the next batch.
No, you generally do not need to rinse kefir grains between batches. After straining, transfer them straight into fresh milk; rinsing can remove some of the microorganisms on their surface.
For a short break, keep kefir grains covered with milk in a closed container in the refrigerator. Strain them and add fresh milk when you are ready to use them again; extended storage can weaken their activity.
Yes, kefir grains can be frozen, but they may not ferment normally as soon as they thaw. Strain them before freezing, then revive them with repeated batches of fresh milk before relying on them to make kefir.
Kefir grains can ferment some plant milks, but they need the nutrients in dairy milk to stay active over time. If you use them with plant milk, periodically return them to dairy milk to maintain the culture.
Yes, kefir grains are edible, though their chewy, gelatinous texture is unusual. You can eat them after straining your kefir, but you do not need to consume them to benefit from the fermented drink.
Discard kefir grains if you see colored mold, notice a putrid smell, or find an unusual color change. Healthy grains are usually white or cream-colored and smell mildly sour; do not try to rescue a moldy culture.
Kefir grains are reusable, not single-use. Strain them from one batch and add them to fresh milk; with regular feeding and suitable conditions, the same culture can ferment many batches.
No, kefir grains are not the same as powdered kefir starter. Grains are a reusable living culture that can grow during fermentation, while many powdered starters are intended for a limited number of batches.

Kefir grains are the living starter culture used to ferment milk into kefir, a drink traditionally associated with the Caucasus. Despite the name, they are not cereal grains: they are small, rubbery clusters of bacteria and yeasts. They are usually strained out after fermentation and reused rather than eaten on their own.
The resulting kefir is tangy, lightly fizzy and often served chilled, at breakfast or as a snack; it can also be blended with fruit or poured over cereal. The grains themselves are best understood as a culture rather than a typical serving of food, and their nutritional character is less relevant than that of the kefir they produce. For a milder drink, ferment for less time and refrigerate it once it reaches the taste you like.
High
How many vitamins, minerals and how much fiber this food carries per calorie. A high score means a lot of nutrition for few calories.
Medium
An EatBetter score computed from fiber, protein and calorie density. A high score means staying full longer on the same calories.
Both scores are calculated per 100 g and do not change with the selected portion. The satiety score is EatBetter's own calculation, not a clinical measure.
