Wish I had another

used this bag just the other weekend it works great for big batches of grains,, only thing is I had to be creative on how to remove the bag of hot grains out of the kettle,, i used 2. 7' latter's a old tubing stick and a ratchet strap to lift the bag , wife thought i lost my mind but it worked,

Everything I expected

I used to use the disposable bags from amazon ($10 per) and now there is no way I’m going back. The sizing worked perfectly with my kettle, and the bag is so big that I know I’m getting better mash efficiencies than using the smaller bags. I also bought the pulley system and it is worth the money if your setup allows for it. From my first batch brewing with the new equipment I saw a 4 point bump in my brew house efficiency (69 to 73%). Highly recommend, can’t say enough good things.

Brew bag for all grain brewing

I highly recommend the brew bag for all grain brewing. It made my operation so much easier. I couldn't believe how easy it was to clean up. Five stars to a quality product.

Excellent customer service

These bags are great. When my original one was shipped, it was damaged during shipping. BIAB worked with me and I had a replacement within days. Great product and great people behind it.


I used to buy cheap draw string bags and I would always tear them on the Temp Probe. The first time I brewed with this I caught it on the temp probe...again, but it didn't tear or damage the bag at all. Really good Quality. After done mashing I empty my bad and let it sit in the sun for an hour. Once it's dry I shake it out and it come out very clean for next use. A++
