Thanks for the explanation. Well, I think you've answered your own question in your OP with what you quoted about separation occurring at the highest possible temperature. I've never heard of whirlpooling whilst cold (before now); to me it's a process that's always been done in the kettle whilst the wort is at or near boiling temperatures.wobbly said:Those familiar with the WW know that it was developed for use with extracts which have been centrifuged to remove most/all of the hot and cold break as well as any hop material and the process is basically charge extract into FV and add yeast to sediment bottle and after fermentation is finished in around 4 days chill contents to 1-2 degrees to drop yeast out of suspension into the sediment bottle. Empty settled yeast as it reportedly can react adversely with the clarification fluid (colloidal silica oxide). Add first lot of clarification liquid and leave for 12-18 hours by which time sediment bottle is about 50% filled, add second lot of clarification liquid and after around a further 24 hours sediment bottle will now be 80-90% full. Remove sediment bottle and consume clear carbonated beer.
As the sediment bottle is only 750mils it is not designed to hold the 2 lts of break material that can/does occur/settle in a typical plastic fermenter.
The issue I am seeking to address is that the fresh wort from my BM results in a significant increase in the amount of break material I have to manage at the end of fermentation requiring at times three lots of clarification and emptying the sediment bottle up to 3 times so I am seeking ways to reduce the amount of break material entering the WW in the first place.
From the following I understand that you whirlpool the "Hot Wort" allow to settle for 15 mins and then transfer to your FV resulting in pretty clear wort.
This is different to what I have been doing (I have been chilling first and whirlpooling the chilled wort) and this is the sort of comment I am after

For me I want to chill my wort as quickly as possible as, with IPA's, my volatile hop compounds are evaporating into the atmosphere and I want to trap them by chilling as quickly as possible so they end up in my beer.practicalfool said:I don't whirlpool very hot either, I let it sit for 15-20 minutes hoping for convection currents to settle down and then whirlpool. Often even direct the first lot of cooled wort back I to kettle to chill it further. I however carry some trub out in the end due to past poor pickup/hop management, the first lots of wort transferred however are clear.
Is there some reason to whirlpool while hot?
