I tried researching this before I started all grain BIAB and never really found a good, reasonably priced bag. Some people said go to a fabric store and make your own but unless I can just buy a sheet and not have to sew anything that is not an option for me.

I currently use these bags from amazon:


5 different bags that I divide the grain into before mashing. It is quite tedious to fill, clean, and tie these so that no grain falls out the top. I found that these bags(each 12'' x 14'') gave me the larges bag volume at a reasonable price. I would much rather use just one large bag and was wondering if anyone had suggestions.

My LHBS carries them, so I pick one up every 2-3 months, depending on how long they last.

Voile curtain from walmart about $5. Wife sewed 3 bags for a 13 gallon brewpot with this material, super strong, so if you know someone with a sewing machine that knows how to use it you could have yourself a few bags made up for next to nothing.

I use a turkey fryer or a 20 qt stainless kettle for BIAB (depends on what size batch I want) and found that the elastic top paint strainer bags from Home Depot just fit and the elastic top stretches tight around the top so I can heat the water to strike temp and stir in the grains without holding the bag. These are easy to clean as when done I just turn them inside out for dumping the grain and rinse them in the sink. Wring out what water you can and hang them to dry, then brush off any remaining grain or husks before turning them right side out for storage. I can make quite a few batches before they need replaced too.

I use a rectangular piece of an old voile curtain. It isn't sewn, I just clip it to the sides of the pot and make sure that there are no gaps that grain can fall through

If sewing something yourself isn't an option, these are quite nice:

wilserbrewer is a member on here who makes custom bags too. I haven't ever used one of his creations, but they get good reviews.

I use a custom BIAB bag I made from Voile curtain material. Mine has a draw string for use with my massive 15 gallon kettle and strainer basket.

If sewing isn't your bag (pun intended) just lay the material out, place your kettle on flat material, gather it all up so your kettle is inside, and cut straight across. You should end up with a circle like object when laid flat again. No you have a semi-custom bag that fits your kettle specifically. When mashing out, gather the edges an tie off with parachute cord. The material has a tight enough weave that fraying shouldn't happen faster than you can brew 20 or so batches. $5 in the Walmart curtain section makes a lot of beers.

BIAB is amazing.

I also use the home depot paint strainer bags. Got two in a pack for I think like $5 or so? They are relatively big, though I don't remember the dimensions.

I use a nylon strainer bag. Not sure where it's from but I only use it on 1-2 gallon batches. Could be from home depot or a HBS.

They are for 5 gallon buckets. I have a 20qt aluminum pot and it fits over the rim and lines to the bottom. I also have a 30qt turkey fryer pot that has the same diameter, the bag does not quite reach the bottom.
