The Brew Bag® - a mash tun filter for Coolers - Round

Regular price $ 30.00

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.

Easy clean up

I use the bag in my igloo 10 gal mash tun - makes clean up easy.

Bilbrew baggins

I’ve used the brew bag for a couple of brews and I’m very pleased with the product. The super fine mesh allows for a fine grind of the grain bill with no worries of a stuck sparge. I haven’t measured but I bet my efficiency has increased.

Better than a bazooka tube

I've used a 10 gallon cooler with bazooka tube for the past 5 years, this is a better experience. No more stuck sparges, I can squeeze the bag to get all of the wort out, pulleys are useful (technology, amirite?). I will be brewing with the BIAB from now on. I have a second 10 gallon cooler, and a second bag, I can make big batches, whatever makes sense! It's great - couldn't be happier.

Great purchase!

I bought this bag based on the Brulosophy recommendations. I absolutely love it! It has made my brew days much easier and more enjoyable. I can not recommend this enough.


Worth every penny. Heavy duty and so much easier to clean and work with compared to any bags I've used.
