NO MORE STUCK SPARGES!!! This filter maximizes the out flow of wort so sparging is not necessary. 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 weight 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.

MrBill
These are great

Even though I don't do a true brew in the bag, it makes my mashing so much easier. Love them.

Kevin Deck
Awesome

I used to have a simple stainless coil for my mash tun, but was getting 65% at best. First batch with the brew bag and I get 80%. Fit great, highly recommend.

Great stuf

Easy order handling.

William Klimko
Perfect

Gives a brilliant, clean wash. I use a lot of flaked maize and it can clog a sparge easily. The bag cleans up that mess.

M
Michael Erasmus
Excellent!

Great product! Getting higher mash efficiency than a fancy setup, this makes doing all grain a breeze! Super glad I got this for my brewing

J
Jason Esterline
Works great!

Works like it should. Only thing I wish I would have done was order it bigger. I want a bigger mash tun now.
