I'd be interested in a BIAB bag. But I'm wondering if anyone here has ever tried doing a 10 gallon BIAB batch. To avoid the problem of having to have arms of steel or a large pulley system how about the following method.
1. Get your mash going with an elevated boiler/bag.
2. When mashing is done empty the wort into another vessel or a couple of buckets.
3. Use a small pot to scoop the grains out of the bag until the bag is light enough to lift.
4. Transfer the wort back into the boiler using a large jug.
5. Continue as normal.
I'm aware that there's a lot of shovelling and scooping and transferring liquid but this method would avoid having to haul a 10 gallon batch of wet grain out of your boiler.
I imagine your bag would need to be fairly well constructed to avoid splitting but if it's already being custom made then maybe that's not a major problem. Any thoughts on this or reasons why it won't work?
