There are many more uses for The Brew Bag than beer making. Some we're sure we've never heard of, but here's the list of known uses and the appropriate micron rating that users have found successful.
Typical product / micron is listed next to the product.
Infusions of ground spices - alcohol, tea, juice kombucha - 55-75
Cold Brew Coffee - 55
Supplement ingredients - 55
Sauces - 55-75-125
Berries - depending on seed size - 55-75
Tea - leaves or ground - 200
Hemp extraction - manual or centrifugal - 125 -200
Organic teas using multiple ingredients - 200
Wine - all fruits - 200 - 300
Wood infusion - chunks, shredded, dust -200 -300 -400 -800

Larger micron openings allow for greater outflow, or through flow if recirculating or washing. Some grains that create a more gelatinous mash require a larger opening to allow liquid to flow out of the bag.
The following benefit from micron openings between 200 and 800.
Cider - 200-300-400
Distilling- corn / barley mix - 400 - all corn - 800
Juices - 55-75-125-200

Plastics - lining waste drums - 200-300-400-800

For reference micron opening does NOT equal mesh size, so the smaller the micron number the smaller the opening in the fabric. To give you an idea of size, 100 microns is about the same size as a single human hair.
Depending on the application, thread (filament) can be manufactured bigger or smaller while the opening is the same. That means the number of threads per inch varies based on the diameter of the thread. Those factors translate to fabric strength and stiffness.
