I’ve done quite a bit of BIAB brewing. I’ve used a few different types of bags. Having used The Brew Bag for a while, I can tell you that it’s the highest quality bag I’ve used. It is purposed designed, by a homebrewer, for homebrewing and that shows. From the reinforced seams to the handles to the availability of a number of sizes to the quality of the fabric. I can wholeheartedly recommend the Brew Bag for BIAB brewing.
