Best Strainer for Milk Kefir
The strainer should be made out of plastic. Kefir milk is acidic and in combination with metal it can result in small electric charges. Some people say it may harm the kefir grains – I do not know, I only used plastic strainer so far.
Finished milk kefir is viscous and not very liquid. The larger the mesh, the easier it is to strain it. However, the mesh must be small enough that none of the kefir grains slip through. Most grains are large and stick together. Smaller grains may detach, but they are still large enough to not fall through most meshes available for kitchen use. The mesh of a tea strainer is probably too small for straining the milk kefir efficiently – it will clog quickly. A larger strainer with a larger mesh will work better. A strainer with a diameter larger than 6 inch (15cm) should do it, but a bit larger is better.
Here is the strainer I use:
And below is the tea strainer that I tried to use at the beginning – it worked, but took me unnecessarily long. I had to keep shaking it, so the kefir milk would get through the mesh.
