Mesh size for straining yogurt? Usually, I strain small batches of yogurt through a cheesecloth, but cleaning the cloth afterward is cumbersome. I'm thinking to buy an industrial stainless strainer (40cm / 16" diameter, 10cm / 4" tall) with a mesh, akin to a flour sieve.

What's the best mesh size that would work for full-fat yogurt? The factory has all the sizes from 12.5mm to 0.003mm (3µm).
Have you seen this piece and the Bouillon strainer mentioned in it? There is no information on mesh size unfortunately.
