Subject: one trip through cfc vs recirculating to brewpot
|
I do 5 gal full boil batches.
I have a chillzilla counter flow chiller.
I can chill to 68 degrees or lower this time of year.
The question:
What are the advantages/disadvantages of running the wort only one
trip through the cfc vs recirculating the cfc output back into the
brewpot until it is all chilled down?
The possible reason for wanting to recirc is to cool the most wort
down the fastest instead of the wort in the brewpot still being really
hot (HSA & DMS) while 'waiting its turn' through the chiller.

It shouldn't make a difference. The main reason to chill quickly is so
that each individual unit of wort chills fast enough to have a good cold
break. That should happen fine just passing the wort through the CFC once,
assuming you're able to reach a low enough temp that way (which it sounds
like you are). Whether the rest of the wort sits around for a little longer
waiting it's turn shouldn't matter.

In a similar vein, is there any logic flaw with recirculating at a high
rate through the CFC to cool the entire brewpot while whirlpooling -
assuming the brewpot output was pulling from one direction and the
input pushing in the opposite direction? I've always wanted to try
combining the cooling and the whirlpool at some point - just let 'er
rip for 20 minutes and cut it off and let it spin down, then drain and
leave the break and hops in a pile in the middle. Anyone do this?

That might work, but why not just whirlpool first and then run it through
the CFC and straight to the fermenter? It sounds easier to me that way.

The reason I don't whirlpool first is to cool down as fast as possible
because that is commonly given as good practice.
After reading Mr Wizard in BYO this month state that it takes the
brewery he works with about 70 minutes to cool the wort (of course it
takes much longer to cool that amount of wort), I may be taking the
cool it as fast as possible a little to literally.
Do you think the better end result in the brew would result from:
a.) whirlpooling the hot wort first then chilling even though that
would be longer for the final cooling. (<10 minutes cooling now).
b.) Cool hot wort quickly then whirlpool the cooled wort before
transferring to fermentor.

I think the best answer to this question depends on the way you are cooling
the wort. IMO, the answer is:
a.) if you are using a CF chiller. Whirlpool to minimize the amount of hot
break you pick up on the way through the chiller to the fermenter.
b.) if you are using an immersion chiller. Since you really need to stir
the wort occassionally to optimize the cooling process, it is pointless to
whirlpool first. Whirlpool after cooling to minimize the amount of both
hot and cold break you pick up on the way to the fermenter.

Agreed.

Whirpooling should not significantly effect your chilling time.
