Default New BYO Aussi brewing article

Does anyone brew like the Aussies with one vessel for both the MT and kettle. They called this method Brew in a Bag.

I brewed in a bag today

Partly because its CRAPPY out so I was relagated to a small stove-top batch

Its the brew club yeast experiment malt bill so its all getting bottled. DOnt mind a small batch for this

My efficiency was damn close to what I get batch sparging (83-84+%)

Yep - done it loads and it works very well. I'd be very interested to see a side-by-side comparison of BIAB and a standard mash tun, to see what noticeable differences there are, if any.

Yeah, it was interesting to see that John Palmer had just discovered something that a lot of people have been doing on here for awhile...It's another confirmation that even "experts" still may have a limited knowlegebase...and also that places like this is where you will often find the "outta the box" and groundbreaking ideas, that eventually end up as part of the canon of brewing and end up in books and magazine articles down the line..

And also what I've been saying since late last year that the Aussie homebrewers are ahead of us in a lot of ways thanks to prohibition in the states kinda slowing stuff down..

There's a couple of great tutorials on here about doing biag...if you search you will find them.

If you like that check out the first ever podcast on homebrewing...the aussies started it as a radio show over a decade agon and have been online for at least 5 or more years.

I currently do mini mash this way and I don't see a reason why not to do the same with AG. What are the main advantages with a 3 vessel system over this method and is it worth that advantage?

The only downside I saw was the need for a bigger brewpot.Otherwise I thought"Damn I've been wasting money on a bunch of un-necessary eqpt."

This is partly b/c of the thin mash which enables you to convert more of the starches in the malt. That offsets the lower extraction rate that you have in the lauter. You basically have a no-sparge when you brew in a bag.

I got 65-75% when I tried BIAB a few times, but I didn't do a mash-out. I've thought of trying it again with my RIMS - kinda goes against some of the principles of BIAB (simple, less equipment, etc) but has peaked my interest.

another efficiency (+) for BIAB is the fact that there is no dead space and that there is a slight squeezing of the grain.

I would even argue that a full squeeze of the grain may be possible w/o a detrimental effect on the beer. I.e. start twisting the bag so you squeeze as much wort as possible out of it w/o bursting it. I take the confidence that this works from the fact that some commercial brewers use mash filter which do exactly that: they squeeze the spent grain to get more wort out of them.
