1-2tablespoonactive milk kefir grains
Instructions
Add Kefir Grains to Milk
Place kefir grains into a clean glass jar. Pour fresh milk over the grains.
Cover and Ferment
Cover the jar loosely to allow airflow. Let the milk ferment at room temperature for 12–24 hours, until thickened and tangy.
Check for Doneness
Kefir is ready when it has slightly thickened and smells pleasantly sour. Shorter ferment times produce a milder flavor.
Strain the Kefir
Place a strainer over a bowl and gently strain out the kefir grains. Do not press the grains.
Store the Kefir
Transfer finished kefir to a clean jar and refrigerate. It will continue to thicken slightly as it chills.
Reuse the Grains
Immediately add kefir grains to fresh milk to begin the next batch.
Notes
Fermentation time varies depending on room temperature and grain activity.Avoid metal tools when possible to protect kefir grains.Kefir grains multiply over time and can be shared or stored.For thicker kefir, ferment longer or use slightly less milk.
