We've seen a good many videos showing how to use a fabric filter to brew in a bag, but there aren't any that detail why this works so well. Here you'll find a bit of science along with some practical information to make great beer in about 3.5 hours using minimal equipment.

Excellent product, fast shipping, would buy again.

I’ve used it multiple times in the past. This is my second bag. Stands up to the heat to maintain mash temperature. Love the loops to hook to carabiners for lifting heavy grains for big beers.

Custom Filters, not related to Brewing

First of all I'd like to thank Rex & the "Brew Crew" for creating a very simple, yet highly effective Custom 200Micron bag for our 1 of 2 Machines in the World for our Optical Lab in San Diego. The bags we ordered showed up in less than 10 days & fit absolutely perfectly. This is not a "normal" bag for the application or brewing...but Rex said, "He's love to take on the challenge". To which he over exceeded our expectations. We have other possible applications which will also create custom applications & he is willing again to take on our challenge. Rex & the "The Brew Crew" are a great asset to have for ANY possible Bag or Application you may want to create. Thank You, again Rex!

BIAB Bag

The shipping was super fast was and the bad feels to well made. I expect this bag to last a long time.

Now on my third one

The first one I left outside and a varmit tried to get to the grain. So my fault. Second one I turned one of the handles off and ripped a (small) hole emptying the bag once. Also my fault. Just received the third one and my first brew with it. Wonder how long they'd last if I wasn't such a klutz ? Great product, reasonable price, smooth delivery. What's not to love ?
