I'm just trying to understand the science of it all, What might be twenty minutes for thirsty boy in the middle of summer with his stainless steel pot transfer through silicon piping via a filtered march pump on a 55 litre boil could be very different for somone in tasmania with aluminium equipment pouring straight into their cube with 20 litres.
How can I adapt the previous information to different equipment.
I have just recently Fudged a brew (suspected anyway) by taking too much time to transfer/cool the wort and I'm trying to work out some more specific calculation to my own setup to determine how not to **** it up next time.
Sorry if my last post seemed provoking. It wasn't intended to be disrespectful, merely to coax some more information from people.
There is no way... you cant do it comparing different brewing equipment when people actually cool their wort rapidly. They might use an immersion chiller, a CF chiller, a plate chiller, do different sized brews, whirlpool, hopback.... dozens and dozens of variations. And thats before you even take into account the 3 or 4 different formulas you can use to calculate potential bitterness in the first place.
No-Chill is no different - in this thread alone there have been several different ways of handling no-chill. So the "15-20 mins" thing is a
starting point - an idea of how it
might effect you. I also think that you can assume, that unless otherwise stated... no-chill will be performed in the "standard" way as described in the articles section of AHB. Beyond that, you simply can't coax information out of anyone else about how it might work on your system... you just have to find out for yourself.
If you are after some of the reasoning and pseudo science behind it, there have been a relatively large number of threads written on this topic - search around and you should get a bunch of different opinions and rationales. Which of them is right and which are bull dust??? Well apart from me being always right as a base assumption
you'll just have to decide which makes sense to you and which matches your own observations about how stuff works.

edit: all of which I guess I could have said by just going +1 to manticle... but I am an annoying wordy ******* at heart really.
