Practice the no chill method and ditch the quick chill thing all together- Im never going back.
Until you end up with a batch that reeks of creamed corn. Slow/no chill will almost certainly result in increased DMS production.
The Ozzies swear otherwise. I've read a lot into the no-chill thing. I'm still a bit skeptical, but plenty of people are doing it.
From the above Maltose Falcons link:
Chill None: Our antipodal brewers are experiencing their own brutal droughts and brush fires currently. Naturally, Aussie brewers are heavily invested in reducing their water usage. One very popular technique amongst them is "No Chill Brewing". The basic process - get a heat resistant plastic vessel (Aussie's like their HDPE cubes) , carefully transfer freshly boiled wort into the sanitized vessel, squeeze out the remaining air, seal the cube, roll it around a few times to ensure even vessel heating (to avoid cracking) and wait. The wait is at least overnight until cool. Once chilled, rack the wort into your fermenter and pitch your yeast. Voila! Done! The Aussies swear you can make great beer via this method - including IPAs and APAs. The consensus from fellow Amurican brewers is to shift your hop additions around and allow for some last minute "flameout" to adjust the aroma.
