Place a non-metal colander over a large bowl. Line the colander with cheesecloth or a heavy cotton cloth.
Pour your strained milk kefir over the cheesecloth-lined colander. If you are using cheaper cheesecloth, you might have to double or triple layer. Store brand cheesecloth tends to be thin, and if not layered, kefir can drip through easily.
Once you pour the kefir into the colander, twist the top of the cloth with a rubber band.
Carefully place the kefir to drain in the refrigerator, allowing the whey to drip over a large bowl. This process can take 4-6 hours.
When the kefir stops dripping, pour the whey into a jar (save for later). For a drier cream cheese, continue to strain it for an additional 3-4 hours.
You can enjoy it as-is, or sprinkle with Himalayan Sea Salt, fresh herbs, or even fresh fruit. Keep tightly covered and refrigerated.
