Why can't you just add ice or at least refridgerated water to bring down the temp. of the wort faster? I don't see any drawbacks to at least slowly adding in refridgerated water to accelerate the cooling.

Thanks,
Doug

You most certainly can do it but bagged ice may contain some nasties that you don't want it you fresh wort. You can make your own ice or use cold water that you know is clean. That said ice or very cold water won't bring a boiling amount of wort to pitching temps. You would still need to cool it down a bit before adding ice or cold water.

There is no reason you can't. Just make sure the ice or water is sanitary. Ice from your ice trays is not sanitary...

yea, if you use ice, make sure to boil it beforehand, and then freeze it isolated from the rest of the freezer. there are bacteria everywhere, even in the fridge and freezer.

if you buy bottled water, you can keep it cold before you brew, and then when you start to brew, put it in the freezer. by the time you need it to top up, it will be close to freezing, and will help to drop temperatures.

Well then why not take whatever water you were adding to your fermenter to bring it to 5 gals (3 gals of water?) and fridge it up nice and cold before adding your wort to it? Maybe chill or almost freeze a few gallons of bottled water?

I use bagged ice from walmart all the time. It's never given me a problem and it's not like they can sell you bad water -- I'm pretty sure they sterilize it before they freeze it, then it's put in a sealed bag.

I use 10 lbs of ice every time, with a 2.5 gallon boil. My yeast usually gets pitched five minutes after flameout. That leaves very little time for those microscopic beasties to take over.

I place 4 gals of PUR filtered water in the freezer about 4-5 hours prior to brewing. It gets the temp down into the 70s every time...unless I brew with 2 gals of water then it's the high 70s, low 80s.

I've been doing this procedure for 13+ years.

you brew with only one gallon of water? you must have to use a tremendous amount of hops to get any decent utlization. i boil off one gallon just through brewing...

Interesting to hear that from HB99. But maybe one should look at it this way: look at all those brews HB99 has put away in a year. Sounds to me like he has a real system going, and don't forget he brews hefe's like a fiend so he doesn't necessarily need a huge amount of hops in them.
