Place Kefir grains in a quart-sized wide-mouth mason jar
Pour organic whole milk into the jar leaving about 2 inches of headroom
Place plastic lid or coffee filter with rubber band over the jar
Place the jar in the corner of your kitchen countertop or in a cupboard. Let it sit out of direct sunlight for approximately 18 to 24 hours at room temperature 70-80⁰F (or until the milk has thickened).
Remove the kefir grains once it has reached the consistency you prefer. (For a thicker consistency, let it ferment longer).
To remove the grains, place the strainer over another quart-sized mason jar
Pour the finished Kefir through the strainer to separate/capture the grains
Place the Kefir Grains into another clean quart-sized mason jar
Add fresh milk, and repeat the process for another batch.
