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

  • Hand wash and drip dry

 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.

Haven't had a chance to use, but it looks good

Game changer

Was using a 10 gallon cooler with false bottom for years. Decided to give this a try... never looked back. I now use it in my 10 gallon Blichmann kettle and have been enjoying shorter brew days, better efficiency, no heavy lifting after setting up a pulley system and easy cleanup. Just ordered another to have on hand as a backup. Three years in and 50+ cycles on this bad boy with no end in sight. Awesome.

Works well, easy to clean

Used my brew bag for the first time yesterday. It worked beautifully getting the grain bed settled and allowing me to start emptying wort out of my mash run sooner without having to recirculate. It cleaned surprisingly easily. Ordering another one.


smaller micron works great, need a good drying rack after washing, it drips a lot

Brew Bag as a mash tun filter

I recently started all-grain brewing with an igloo 10 gal round cooler for a mash tun with a false bottom. After a few batches where the draw tube became mostly-to-completely blocked making vorlauf/lauter almost impossible, I purchased the Brew Bag to use essentially as a filter. I kept my false bottom/draw tube setup with the bag on top of it. I mashed, vorlaufed, fly sparged, and lautered as I had been doing and the difference was amazing! The vorlauf and lauter were clear and flowed easily. I am sold on this setup. I went from being rather discouraged with the whole all grain process to planning many upcoming brew days. If you have a similar setup and have struggled with stuck sparges, I would highly recommend getting the Brew Bag. It will make for a whole new experience.
