Home brewers BIAB

I looked at it a long time before opting for the more traditional path. It's just a supposedly easier way of creating a filtering system for your mash. You still need a large vessel and if you're planning on using your boiling vessel, it will need to be larger than you actually need for boiling. Example: For a normal 5gal brew, you'll need a 10gal boiling pot, whereas normally you could get by with maybe an 8gal. Since you wont be sparging, your grain bill will be larger.

I built my own mash tun and it isn't that expensive or difficult.

Personally, I have never tried it but it always seems like more work.

I get typically about 75% double batch sparge and close to 80% if fly sparge w a mash out.. This using a false bottom converted cooler setup. I generally batch sparge and plan for it in my grain bill.

There are a lot of factors that play into efficiency including how crushed the grain is.

I have not tried the BIAB method so I wouldnt be able to help there sorry.
