Biab: How Fine A Mesh?

[rshwayder]

I'm over here in the states and I'm looking to make a bag for "Brewing in a Bag." Most of the Swiss Voile I can find out here is made with cotton, which is obviously not the material of choice. So, I'm looking around for Nylon mesh, and I need to know how fine a mesh I should be looking for. While I get that finer is generally better, there is nylon material all the way down to 1 micron (which is insanely expensive and obviously the wrong size), so I'd like actual mesh gap sizes if you know of them.Thanks!

About this fine.

Wow, that's impressively fine mesh. 0.5-1mm? Thanks for the pic.

and although nylon works OK - 100% polyester is the material that most BIAB brewers are using. Nylon is fine if its all you can get, But I would go with polyester.

The polyester voile is usually next to the curtains, in oz anyway.
