Review on Premium Quality Bellamei Nut Milk Bags - Reusable 2 Pack Food Strainers For Homemade Almond/Soy Milk, Yogurt, Cold Brew Coffee, Tea & Beer With Fine Nylon Mesh by Pat Nard

We've tried several ways of making cold brew, from just putting grounds in water and filtering the result, to using the stainless mesh tubes, to these. This is the best so far. ZERO grounds make it through, and it drains very quickly. The grounds are almost dry after just 20 seconds or so of letting it drain. We've been using the medium bag in a large plastic food container. The bag is strained coffee color now, but it continues to work great. We hand wash it and air dry it.
