After hanging the bag to drain in BIAB do you squeeze the bag?
I do as every drop is more wort, but am I wrong?

I also cite the pioneers of BIAB, the Australians saying to go ahead and squeeze the bag later in the discussion.
I'll be buggered if someone in the good ol' USA can convince me I'm wrong about that!
suprchunk;2051308]Seem to have a bit of a hangup on Americans. I haven't seen anyone in the "good ol' USA' trying to single you out and convince you that it was bad. On the contrary.
I had brewed this way a number of years ago, but was unaware that is had a name and was actually being employed. And I didn't squeeze because all of the literature at the time advised against it. I'm not a scientist so I had no means of measuring the amount of tannins extracted. But it seems as if someone has.
A while ago when the "no chill" (or hot wort straight to a sealed air tight container" was in session on this site I remember the ballywhoo coming about botulism and other maniac suggestions. The American public know all about pre-emptive strikes, so I reckon what's good for the goose is good for the gander.
Yes, it has been around for a long time in a few different countries, but has been popularised and championed by one Aussie brewer in particular who has taken the concept back to the masses. When squeezing your grain bag you are putting minimum pressure on the bag. Most BIAB bags are capable of being suspended in the air and spun around and therefore squeezed to allow the wort trapped betwen grains to be pushed out. It would need a fantastic (and unlikely) amount of pressure to be further placed on the bag of grains to squeeze tannins out of the spent grain. As we shed brewers are warned, mash/sparge out at no hotter than 80 degrees celcius (do your own conversion) as hotter temps will extract the tannins from the grain. It is the temperature that causes tannins to be released, not the squeezing.
In simple truth, you can't get every bit of wort out of the bag no matter what, and the small amount you have left after you have taken the vast majority of the sugars in the wort will have minimal impact on the final outcome.
Simple solution, get your runnings, hang you bag and squeeze it for the small amount of wort that gravity alone is having trouble extracting.
stupid american pig-dogs. i fart in your general direction.
Racism/continental discrimination/sexism is hilarious. intended or not. just enjoy it from an objective perspective.
In all honesty, i don't see anything anti american here. and if there is, i personally invite fatgodzilla over to my house for a fight and a beer. oi oi oi!

Not to those on the receiving end of Racism or Sexism. Maybe the continental crap gets a pass IMO.

skidaddytn --I resisted the urge to squeeze the bag today... however, I was definitely thinking about it!!!
howdo ------
I reread my post. When I said "I enjoy that stuff too it" sounds like I enjoy the "Racial/continental discrim...". Thats not what I meant. I meant I enjoy a good debate about political stuff. See, the earlier post was right , sometimes it is hard to get the exact connnotation with text.
My apologies to all, as now I have really derailed the topic. Lets get back to beer talk!
Yes, I can't work out how you got to here from my comments, but its good you are willing to get back on track. I actually think that apart from a comment that shows some people really have no sense of humour, my answers were beer related and actually relevant to the original post. I have been waiting for people to attack my arguments, or raise issues such as pH of the wort that also leads to leaching of tannins from the husks, or the concern about the too fine crush. But clearly that is for another audience.
My apologies if anyone found offence in my comments.
Loves you all long time

So does anyone have a legitimate reason why not to squeeze the grains to avoid absorption loss?
I can see how he got there. Because that is not the only time you have done it, berated Americans that is. I don't think it is humorous to generalize a whole continent based on your very limited interaction with people from there. I would hate to have to stereotype all Australians based on your comments. Fortunately I've met many friendly people from down under to not have to use you as a sole example. That and I might be at fault for not thinking one person represents an entire continent.
And the question was specifically about squeezing the bag. If you wanted to introduce pH or any other factors that would increase tannin extraction, you could very well have done so - without again berating people with a comments such as "But clearly that is for another audience".
Might be time to climb down from that high horse and start slumming it with the audience you signed up to participate with. Unless we are too lowly for the likes of you.
Sorry to vent. But when I see back to back posts from you assuming that a whole continent does the same thing, and perpetuates it, it just rubs me wrong. You may have meant it as humorous, but I really don't see how it could be taken as anywhere near funny.
I think you're overreacting. And I think your earlier post was too. I didn't interpret any of Fatgodzilla's posts to be discriminatory, only informative and hilarious. Since when do people not joke around on hbt? That's one of my favorite things about this forum.
Australian's are known to be insensitive to emotional strangers. Fact.
I didn't either. I was part of that idiotic No-chill thread,( In fact I may have been the one who started it)

I guess you're right. Never thought about clumping a whole people by the actions of one, but if you're providing the empirical evidence, and I think you are, then I can only concede that this is, indeed, absolutely true.
Why not just sparge? Is that possible with BIAB?
Here is the method I use to squeeze my bag. First I open up Firefox in Private Browsing mode... oh wait, we're talking beer.
Seriously though, I picked this method up from the Aussie BIAB forums. I lift my bag out of the kettle and put it in my fermenting bucket (you can use any bucket or container). At the bottom of the bucket I place a pasta colandar pot up side down. While holding the bag over the bucket, I twist the bag so as to compress the grains. I then lower the bag inside the bucket, and set it on top of the colandar while holding the twisted portion of the bag. I then use a pot lid to squeeze down on the bag. I wear heavy duty rubber gloves while doing this. I'll do this a few times before dumping the collected wort into the kettle.
I also sparge in the fermenter bucket because my second kettle is not that big. I heat up my sparge water in the smaller kettle, then dump it onto my grain bag in the bucket. I let that sit for 15 minutes. I'll do a twist on the bag to drain it a little, but by that time I usually have enough wort.
do you have a link to the aussie BIAB forum you referenced?
http://www.biabrewer.info/ is the site. It has a PITA registration system, but it is worth registering so you can download the excel spreadsheets.
thanks man... hows the discussion?
