[quote=“tom sawyer”]I use a 25fter for my 5-5.5gal batches and it would take the kind of time you’re talking about. I recently found that if I stood there and stirred continuously, I could get to 90F in under 15min. It does mean you have to stand there though. At that point I rack to the fermentor and put it in the basement on the concrete or in a swamp cooler. It usually takes at least a few hours before its at pitching temp, and I often leave it overnight before pitching with no adverse effects.
That is exactly what I should have done Saturday night. It just made me nervous to leave the wort in a somewhat vulnerable state for so long. I admit I probably wasn’t thinking very clearly at 2AM. With proper sanitation, I guess it should be fine to let it sit in a sealed carboy until morning.
That said, your plate chiller is going to cool quickly and the only time limiting factor is going to be how long it takes to put all your wort though. Thats why I think you might as well get a pump. I finally broke down and bought one and it is a useful addition to the brewday. For your setup, you’ll be able to pump through the plate chiller and right into your fermentor and be done in something like 5min from what I hear.[/quote]
When I do my dry run with the plate chiller, I’ll time how long it takes to drain the kettle (using a ball valve) so I can calculate flow rate. I’m also curious how flow rate affects cooling efficiency. I may not want to send the wort through at warp speed.
I’ve been thinking about sending the wort from the kettle (through the chiller) into a bucket, whirlpool to get the cold break to settle out, then rack to the carboy. Since I got the 1/2" auto-siphon, it just just a few minutes to rack. Is this overkill, though?
