The Brew Bag® for 10 gal Round Coolers & Larger Kettles

I've been using an inexpensive voile bag in my 10 gallon cooler for mashing. It has developed some holes over the 6 years I've used it and grain particles started to leak out into the wort. I use a bazooka screen to enhance the flow of wort. With this set up, I simply batch sparge without vorlauf for a high efficiency mash. The new bag is a great improvement. The material is more substantial. Mesh is more dense but it still filters well. The handles and the reinforcing webbing make it easier to remove after mashing. Very few grain particles stick to it. I empty it into my compost pile turning the bag inside out. Cleaning is as easy as soaking and rinsing the inside of the bag. I'm greatly pleased with this improvement to my brewery. It is worth the extra price for the better design and material over my old generic $7 voile bag.

This bag is awesome!! I no longer have to vorlauf! Saves time and energy.

I have been a cooler mash tun brewer for 6 years and just recently got one of these bags. In the past I used some of the cheap nylon bags, and false bottoms, and combinations of the two, but this worked far better than those. The bag is a good fine mesh, and I didn't get any grain particles coming through during recirculation resulting in very clear wort very quickly. Cleanup was very easy. I just turned the bag out to dump the grain into the trash then washed it inside out. The inside surface doesn't have much for things to stick to, so it rinsed out with minimal effort. I should have gotten one of these years ago.

This is a well constructed bag with heavy-duty lifting straps that is plenty big enough to fit in a keggle (I have the 10 gal size). By mashing out in the same kettle I brew in, I've completely eliminated the need for a mash tun. I put a round stainless cake rack in the kettle (to keep the bag off the bottom- not necessary if you are not going to add heat during mashing), add strike water, bag, and grain. I wrap the kettle with a fitted piece of duct insulation and start the clock on the mash. I started out using a standard mash rest, just stirring occasionally, but have since added a recirculation pump and sparge arm to the set up. Throughout the mash, I continually move the wort through the grains, adding heat as necessary to maintain mash temps. This gives me 10-15% greater mash efficiency and a clearer wort. When mash out is complete, I use a pulley system to lift the grains out of the wort and suspend them while I pump (or pour) my sparge water over them. Some say sparging is not necessarily with BIAB, but I figure what the heck, I'm going to add hot water to top up my kettle volume, I may as well rinse the remaining sugars out of the grains while doing it. When all is done, I just haul the spent grain out into the woods for the wildlife to munch on. Too easy! I highly recommend this product.
