  • Nylon forms 4 loops at the opening of the bag that make great handholds or can be used with a winch system

Perfect for Brew in a Bag, this large 27.5" x 32.5" bag will fit pots up to 19" in diameter. These polyester bags have 1-inch wide nylon sewn over the seams, making them incredibly strong and resilient. At the opening of the bag the nylon forms 4 loops, making great handholds when lifting the bag or attaching to a winch system for large BIAB batches.

Please note: when removing the bag from your kettle, always be sure to avoid thermometer probes and other accessories that may snag and tear the mesh. Be careful when using mash paddles and spoons, especially when the bag is full.

I have other plastic brew bags that do not have the support that this one offers. I want to see if the additional support will make my brew days easier and I want to see if the bag will last longer

Used it before and it worked perfectly, until I left it filled with spent grains for too long and went moldy. Then it proved next to impossible to clean.

Will this burn on an element at 160F?
Joshua Sandt on Dec 23, 2018
I bought this bag in my first order from Morebeer but it doesn’t fit my 19.7” diameter kettle. Did I receive the wrong bag and will this actually fit kettles up to 21.5” in diameter?
Brandon M on Mar 26, 2019
BEST ANSWER: Hi Brandon - After physically checking the bag in our warehouse, it is definitely the correct bag we have sent. Unfortunately though, I did a little test and it barely fits a 18.5" diameter kettle. So that is a mistake on our part which I have contacted our product team to get that description changed. I will continue our correspondence through email. Apologies for the inconveniences that have been experienced.
is it big enough for a 65L brewzilla?
Andres Castillo on Feb 22, 2022
Is this bag the right size for a keggle BIAB set-up?
Eric Bard on Jan 29, 2019
BEST ANSWER: Yes, it's plenty big with room to spare. My other well-known bag is 16 x 23 and has a decent amount of extra slack. So you will likely need to manage the extra bag length on this one but it will certainly fit.
Can this be used with the 10 Gallon Anvil Foundry without the malt pipe?
Nick Arleth on Jan 22, 2023
BEST ANSWER: Yes. I use it with my 10 gallon Foundry. It is about right for the depth, maybe a little short, but the diameter is larger than the Foundry so there is some excess material. Overall it works well enough. I believe there are Foundry specific mesh bags available.
Does this fit in a 10 gallon igloo cooler mash tun?
Duane Weidendorf on Aug 14, 2020
BEST ANSWER: Yes, I use this in a 16g Bayou Classis kettle used as a mash tun and I have extra material coming out the top. Just tried it in an igloo and had 4-6 inches of extra material out the top, should be fine.
Can holes in the bag be repaired?
John Kaiser on Apr 28, 2024
BEST ANSWER: Not really, I believe its expected to replace the bag after a few brews. Ive been able to reliably get 50ish brews out mine. Even with holes you should be able to finish up your sessions

Ripped The first use
Bag ripped the first time I used it dumping grain into my kettle that I had to filter out. luckily I still had my old bag. May have just been defective.

Holds a lot and can be hoisted
This bag works very well. Just don't use it if your kettle has a thermowell. The well punches holes into the bag very easily. Just remove the thermowell before making your brew.

bag worked for 4 brews then fell apart at the seams
bag worked for 4 brews then fell apart at the seams on the 5th. Lost 16 pounds of pilsen malt and 8 pounds of 2 row. Very unhappy.

Good Size BIAB
I can easily fit the grain volume needed to a 5 gallon brew. The webbing is strong and can support the bag while hoisted. However, this is my 2nd time ordering this bag and, like another reviewer mentioned, holes developed the very first time. The first bag held up much better which makes me wonder if this one is exactly the same bag being sold as before.

Great buy
Worked beautifully. Allows me to utilize a finer grain increasing efficiency and keeping grain out of the boil which ruined several batches prior to this

Seems like a solid bag that could hold a lot of grain with no issue but I have two issues with it:

1. Somewhere on my second brew I noticed a few holes already forming in the bag. So far they have remained small enough to not cause major issues but I don't have high hopes for the future.
2. The bag seems to get bits of grain stuck in the bag around where the straps are that is really hard to get out.

Will probably keep this as a backup bag or maybe for other purposes.

Anvil 10 gallon stuck mash solved
Plus 2 lbs rice hulls in 15 lbs grain instead of 20 grain+1 lb hulls, and strike water to top of grain bed--7.5 instead of 6.5 gallons...with fluidized bed and this screen can now run the pump rate up sufficiently to expedite step mash temperature increases--was taking hours at low flows, and then stuck totally halfway through, nothing worked---holes in basket plugged, bag solved it totally, does not plug or slow flow rate. Still no 1.1 OG was getting with gas fired kettle/ice cream maker stirrer...but passable 1.055 so far. Try less water next time, can always add more. Bag tears easily on screws sticking out of grain basket when you dump the grain so remove the bolts and use flatheads, sewed the holes shut with sewing machine ok,. Maybe ditch the basket and use false bottom with this bag and get better flow through the bottom of the grain bed.
