Best bag money can buy

The only way you would need a new one was if you burned it or really caught it on something sharp. It’s pretty much indestructible besides that. Couldn’t ask for better.

Heavy Duty Quality

To be honest, I have not brewed with this bag yet. but upon examination this bag is high quality and should last a long time. I have another of these that I use in an igloo cooler mash tun and it has not let me down.


This product is great what a great company as well

Quality, Practical Product, Excellent Customer Service

I just received my second Brew Bag (400 micron, made specifically to fit the 35 liter Gen 4 Brewzilla). The first is larger, and I have used it for over a year, primarily when siphoning my wort from the brew kettle to the fermenter, thereby capturing almost all the trub. I recently acquired the Gen 4 Brewzilla, and I have used the Brew Bag in the pipe for the last three brews. It did not restrict the recirculation flow, and it also prevented grain material from clogging the pump. The wort came out very clear. I use the same bag again when transferring the wort from the brew kettle to the fermenter (with my climate I boil in a separate kettle outdoors).

This new Brew Bag fits the inside Brewzilla kettle perfectly, with the handles extended to fit around the top and outside of the Brewzilla (thus the pipe is not needed allowing for larger mashes). The lid can still fit over the bag handles. I can’t wait to use it, as my other bag was too large, and as a result was a little difficult to keep attached.

The bag is very rugged, with four handles, and no amount of grain would be heavy enough to rip the fabric. The fabric material is also not absorbent, so it is extremely easy to clean and dries suprisingly fast.

I also had very excellent customer service after initially receiving the wrong bag. They were quite concerned and replaced the bag very quickly.

This quality Brew Bag solves some of the recirculation issues with the Brewzilla, and also removes most of the trub from your brew. It is also very easy to clean and dried rapidly. I recommend it highly.
