There are three primary methods for removing milk kefir grains from finished kefir:
Use a plastic mesh strainer. Since milk kefir (aka dairy kefir) tends to be a bit thick, you may need to use your fingers (in a swirling motion) to help work the kefir through the strainer but this method will leave you with a uniform consistency for the kefir as well as safely securing the kefir grains in the strainer so they can be added to fresh milk. Check out the this plastic mesh strainer available on our website. Stainless steel can be used if necessary--just be sure it's stainless steel and not a reactive metal.
Use a cotton muslin bag to secure the milk kefir grains. You will want to be sure the bag is secured at the top so the kefir grains don’t escape as well as big enough to allow for some growth from the grains. Place the bag containing the grains in the milk and allow to culture as normal. Be care to ensure the bag is kept submerged in liquid as floating bags attract mold. We have two sizes of cotton muslin bags(small and large) available on our website.
Use your fingers. As your milk kefir grains grow in size, you can often use your hand to remove the kefir grains quickly. Make sure your hands are very clean though or you risk contaminating your kefir and the kefir grains.
