This bag is a complete game changer. It fits perfectly in my Brewzilian gen3. The final brew was so clean. There was very little residue in the bottom. Clean up was easy and fast. Highly recommend this brew bag.

Durable and exactly what we needed. We almost ordered the wrong micron, and a member of brew bag emailed us before putting in the order to make sure we were getting the right bag for the job!

Top notch bags made to order. I've been using mine both for mash as well as for filtering accumulated sediment when moving to secondary fermentation. Also works great with wine so you can keep any fruit skins in the wine for longer and get more fruity exxpression. I was a little worried about how heavy a full bag would be (about 100 lbs) but the bag has zero issues handling this at all when held correctly. The straps are also very handy to prevent slumping back into the vessel when draining to avoid having to lift it out of liquid at full weight and draining. Company itself shipped quickly enough and it arrived clean and exactly as I ordered it. Note if you're going to get a zipper to add some inches to your diameter calculations because a zipper doesn't invert to the same size as the bag material would with a normal opening.

This is my 3rd bag, 1 for each of my mash tuns, I have never had an issue. My first bag is over 8 yrs old and still holding up strong. The price is extremely good for the quality. They are extremely useful for BIAB methods or I use them in my 3 vessel system. I have shoulder issues and use a pulley system to lift grain out of the mash tun and makes clean up easy

We were so impressed that right after ordering our custom brew bag, a design specialist called us personally! They took the time to help us make tiny adjustments to the dimensions and add extra elements to ensure our bag was absolutely perfect. Such wonderful attention to detail

Ordered some brew bags to collect duckweed at my wastewater lagoon system. Got a call from Brew bag making sure I was ordering the right thing. Very helpful on the phone and gave me the confidence that what I ordered would work for the intended use. Will order again from brew bag.
