harr.. Paint strainer for BIAB
|
|
I thought I could use a "5 gallon paint stainer bag" as a bag for BIAB... but to my great surprise, 5 gallon is not the size of the bag! The bag is smaller.. it's like the half of the size of a carboy (so 2-3 gallon).
I suppose I'm on my own to make a diy BIAB grain bag out of a piece of curtain.

I think I read that the "large" bags from Brewmaasters warehouse are pretty large? YMMV

I was aiming at a 2.5g batch and I heard that you need twice the volume cooking pot for when the grain is inserted. Also the bag has to be big enough to fill the whole cooking pot. So that leaves me to make a 1 gallon batch with my paint strainer

Not really, the bag you have should work out just fine for 2.5 gallons. My VLGB is about 5 gallons, but I've used it without any problem in an 60-quart kettle.

If I'm brewing smaller batches that would only require a couple lbs of grain, is there any reason a strainer bag that is large enough to hold the grain but not large enough to stretch around the pot wouldnt work? Meaning I would have use it more like steeping, I can see it would make stirring the grain difficult but is there anything I'm missing?

I use 5 gal paint strainer bags all the time from lining my 5 gal igloo mlt to using them as hop bags. They work for everything. Are you sure you got the right size? I've had 12 lbs of grain in one before.

You got the wrong size. Those bags are made to line the inside of a 5-gallon paint bucket. I use them all the time and they are F*CKING AWESOME.

the 5G paint strainer bag i got at LOWES fit nicely over my 5 and 7 1/2 gallon kettles.
whats the best way to improve efficiency using this method. i brewed like this and got OG 1.040 when it was supposed to be around 1.055. Mashed for 90 minutes at 152 and single sparged at 170. I know I didn't boil off enough water (about 1/2 gallon left in the kettle) but that shouldn't account for that much of a miss.
this is my grain bill:
5 lb American Two Row
1 lb Crystal 10
will the crystal 10 not convert as much, thus accounting for the large miss since 16% of the grain bill is crystal. 5 lbs of American 2 Row should yield 1.040 for a 3 gal batch.
