Default chilling full boil AG without wort chiller?

i havent had problems chilling partial extract boils in the sink with ice. im kinda broke at the moment to buy a wort chiller, but gonna be doing my first AG soon. wondering what kinda techniques folks out there use for chilling full boils (5 gallon). ive heard something about kettle in ice bath + salt in ice bath + swirling the wort slowly? is this accurate or is there any other technique people are doing that dont use wort chillers for full boils?

This is one of those things that theres really no trick to. Id just buy like 6 bags of ice and have a big sink to do it in, fill it with ice and water then salt the ice, its still gonna take a while.

I predict youll spare some money for an immersion chiller after going through this.

+1 on the prediction.

This is where the wort is most vulnerable, and a lid on the brewpot is going to make your chill time seem like an eternity.

When going from extract to AG, there are some obvious pieces of equipment needed...and a couple of no brainers. I consider a wort chiller one of the no brainers.

(temperature correcting refractometer is the second one IMHO)

If you're looking to avoid using a wort chiller for AG, I'd strongly suggest going the no-chill route.

If you transfer your wort over to a HDPE bucket immediately after the boil while everything is still scalding hot it'll sterilize your bucket and keep everything nicely safe so you can pitch the next day. Most people I've read about doing this will stuff the grommet hole with a Starsan soaked rag so the bucket doesn't collapse under the negative pressure as it cools. A bubbler full of Starsan/Vodak would probably be almost as effective.

In case you're wondering, HDPE is still food safe at boiling temperatures (it's the same plastic they use to make the the boil-in-bag rice) it just softens slightly, so don't kick your bucket.

+1 on the no chill route... http://www.usplastic.com/catalog/item.aspx?itemid=31615
Order one of those and once the boil is done you just dump it in there and let it cool over night.

I just leave the lid on the pot and then set it in my bathtub that's filled will cool tap water. I'm typically at 80F within 30 to 45 minutes. Commercial bags of ice can add a whole lot of cost to your batch of beer!! As for how sanitary this is.....I'm pushing my 40th batch of beer and have yet to lose one to contamination.

Sanitary would be a secondary concern for me in that situation.

Carrying 5+ gallons of 200+ degree water would scare the crap out of me. I worry about moving mine the 3 feet from my stovetop to the sink enough that I've been debating getting longer tubing so I can just leave it where it is.

Admittedly I tend to be a bit paranoid, but I've manged to avoid setting myself on fire for almost 15 years running now.

Ahhh.....there's nothin' to it, brother!! Just gotta grab that pot and show it who's boss. Besides...just knowing that you're carrying 5+ gallons of 200+ degree water has a way of making you step carefully. LOL!!!!!

what about salt on ice water in bathtub? what about stirring the wort slowly while its in the bathtub? ive heard these techniques can help alot for full boils if you dont have a wort chiller. anybody had success without using a wort chiller? im kinda shaky about the no chill route...

Salting the ice will help you with the last few degrees, it will lower the freezing point of the ice, but it can't touch the amount of heat that a given amount of ice can absorb (laws of thermodynamics and everything.)

And I think Bacchus answered whether anyone has had success with using the bathtub for chilling 5 gallons of wort.

If you had access to piles of ammonium chloride (pulling that from memory as a salt that has an endothermic reaction with water) it would work for chilling the wort reasonably fast, but long term it's going to be a heckuva lot more expensive than a copper wort chiller.

You really might want to research no-chill though. The Aussies have (apparently) had a lot of luck with it, and I've never heard of anyone trying it and then going back to the git-er-done chilling camp. (I've never done no-chill myself, but then I'm from the deep south, so git-er-done is pretty deeply ingrained in me.) From everything I've heard the only effective difference is that you pitch your yeast the next day. There's no noticeable DMSO off flavor or long term flavor instability, just half an hour less work on brew day and an extra 10 minutes on the day after.
