I bought SS china cap strainers (stackable) of varying pore sizes, e.g., coarse/medium, fine, and buillion/extra fine, with the plan of progressive straining. Turned out that the pore sizes for SS coarse and fine were still too large. Buillion/extra fine works well for hop pellets--only the finest hop pellet material continues through, but is caught by the plastic mesh screen on my large plastic funnel. Break material seems to continue through regardless.
Have you ever tried stacking the plastic strainers in series with progressively smaller pore sizes, i.e, 400, 200, 100 microns?
