 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.

From 50% efficiency to 80% efficiency

I thought I could do brew in a bag in my kettle with a couple muslin bags I had around, and wound up losing a bunch of temperature and having to compensate on the fly by reheating the water and wrapping with towels. Only got 50% efficiency, getting a 1.020 OG out of 4.5kg of grains. So I bought this bag to go in a cooler I already had, did the same recipe, and wound up at 1.060, 80% efficiency, just from this bag and closing the cooler. More importantly: I enjoyed it more. I actually got to sit back and wait during the mash instead of monitoring heat loss in the kettle. Absolutely worth it.

awsome brew day

Did my 10 gal of a almond porter sitting in my 14 gal ss fermenter the grain bag did what it was ment to do held 22lb of grain and drained great!!!!!!!!

Great customer service

Worked perfect

Second BIAB

I picked up a second BIAB for my mash tun for big beers. Works fantastically! The Brew Bag makes the best bags out--without any questions!

Sturdy and well-made

I haven’t officially brewed with it yet but it fits perfectly in my 72 quart Coleman cooler. I will be doing a Sierra Nevada pale ale clone this weekend and I am sure I will not be disappointed.
