NO MORE STUCK SPARGES!!!  This filter maximizes the flow of wort. Just put The Brew Bag® in your cooler, add grain and strike temp water as usual. When the mash is done follow your normal sparging procedures and then open the spigot and drain into the boil kettle.

Features of The Brew Bag® for Coolers

  • Use again and again - NOT a throw away bag

  • 2" loops for lifting - either by hand or with a pulley and a hook

  • Holds over 100 pounds of grain

  • Smooth seams on the interior enable quick cleaning

  • All strapping intersections are reinforced with "X" stitching

  • 1" poly straps cover seams and bear the strain of grain - this bag will last and last

 Additional Benefits of The Brew Bag® for Coolers

You can also use the The Brew Bag™ as a complete Brew In A Bag NO SPARGE mash tool. Just calculate the full pre-boil volume, add approximately 12 ounces more water per pound of grain (this will be absorbed and tossed). Then just open the spigot and drain into the boil kettle. You may need a bigger mash tun for this process.

The best way to mash!

The Brew Bag for 10 gallon coolers works perfectly! I have brewed with the bag twice now and have hit my pre- and post-boil gravity targets each time. Out of habit, I still sparge with the bag as one would with a traditional all-grain system. Clean-up is a breeze. Anyone who is still using a false bottom, sell it and purchase the Brew Bag! Luckily, I have a ceiling hook in my pantry, so a pulley system was not required.

Brew bag makes brewing easy and efficient.

I have the round 5 gallon brew bag and it is perfect for doing small batches in the kitchen. It fits great and the fine mesh keeps all the unwanted ingredients out of the wort.

Perfect mash tun filter

I have used the brew bag as a mash tun filter (mash in a cooler in a bag) for several brews now and could not be happier with the results. This is my first experience with all grain batches. I place the bag in a 10 gallon round igloo, fill with 165 degree water, and add the grain. The temperature typically drops about 10 degrees, and after an hour I simply open the valve to drain the wort into the kettle. A quick squeeze of the bag, raised above the kettle with a pulley, and I have 6.5 gallons of crystal clear wort ready to boil. No lauter, no stuck sparges, and have hit target OG every time. Simply dump the grain and rinse the bag to clean. It is well made and durable, and has made the process very simple.

Excelent product

I've been doing biab for a year now with the bags I could find locally. Last night I brewed for the first time with this bag and I won't be looking back. This is THE bag. Excelent build quality, fits perfect, no more fetching my bag inside the cooler.

2 Happy brewers

So far we have made one batch using the brew bag and are pleased with the result, our OG was on point due to a finer grain crush that would have led us to a serious stuck sparge without the bag. Clean up after mash was quick and easy - no more shovels in our mash tun.

We will be buying a second brew bag in the coming months for our secondary tun.

Thanks for such a great product!
