Therefore I still say it makes a difference and Nath shold try it if he is so sure it does not work.
How do you know i haven't tried it?
I know you're not comparing it to 3V brewing, but the reason i brought it up, was that people have different perspectives of how clear is "clear" sometimes, and if you have nothing to compare it to, then i'm sure you're getting clear beer/wort.
Those "small particles" that you see in your grain bed? They are getting trapped are in everyone's mash whether they sparge, recirculate, biab or 2V/3V/4V brew. I see them in my mash tun and i see them in my BIAB post draining.
The even smaller particles have already fallen out of the bag/mesh as you've raised it. they are now in the bottom of your kettle.
Just because pouring your wort back through your grain probably appears to come out clearish or even super-*******-clear out the bottom of the bag, doesn't mean your method is working. Damage has already been done (so to speak) in my opinion.
If you're sure that tipping wort back through a hanging grain bed in a mesh bag is a good idea, then keep going with it.
I am suggesting, you may not understand just how clear wort CAN be going into the kettle, hence the comparison to using a mash tun. If you ever use a mash tun, and recirculate in that, (where the grain bed doesn't get disrupted) when you open the tap to transfer the runnings to kettle, THEN you'll understand clear wort. You're wort in a biab setup will be cloudier as soon as you START to lift the bag, before you even see the runnings coming out of it, and this is where i'm saying your method is in some ways, pointless.
What i would suggest is that instead of using your wort to do what you're trying to achieve, why not try doing it with a fresh supply of water?
It's the same thing right??? :huh:
Have you considered that you might actually be trapping some of the sugar that's in the wort by running it back through the grain bed? Using clean water guarantees that you won't have this POTENTIAL problem, it'll also yield higher effiiciency - that's not a guarantee, but it certainly is a guarantee that your efficiency won't go down as it might if you lose some of the sugars by using wort to pour through the bed.
But hey, what the **** do i know.... there are several other brewers in the last few posts who agree with me, and are telling you that there might be a better way.
Both Kev and Crusty, are MUCH more experienced brewers than myself, i have learnt heaps from both of them over the years. I'd listen to them.
EVERY brewer i've talked to, read from, asked questions too, seems to universally accept a more turbid (cloudy) wort going into the kettle when using BIAB methods. It is what it is. Can't really do a whole lot about it, so we move on and improve other processes to regain our clarity if required, further down the brewday path - Better whirlpooling, using flocculation agents, get better at transferring post boil, cold conditioning, gelatine, filtering...**** the list goes on...
You seem to have stumbled on a magical process that works for you and only you, so keep doing what you're doing.
oh, and i don't really like horses that much. Certainly not enough to climb up on one.
