[quote=“Rookie L A”][quote=“CasperKat”]I’m making 3 gallons of wort, adding it to my fermentor and topping off with cold water to make my 5 gallons.
The cold water being added is about 55 degrees. If I cool the 3 gallons of wort to 90 degrees, I should reach 80 degrees or less almost instantly by mixing it with the new water in the fermentor.
Is there any bad side to this?
The alternative is waiting a lot longer to cool to 80 degrees because I still haven’t purchased a wort chiller. (I’ll get there eventually)
But, for now, I don’t see a downside to this, except that if I don’t reach 80 degrees, it’s much harder to drop the 6 gallon carboy in a bucket of ice.[/quote]
I brew three gallon batches all the time and chill them down to 70 in less than 30 minutes without a wort chiller.
I freeze 5 or 6 one gallon milk jugs filled with water. I add them to my bathtub as I fill it with cold water. I put my brew pot in the tub with the lid on and swirl the water around it every couple of minutes. Every 5 minutes I lift the lid just enough to gently swirl the wort with the floating thermomoter that’s in it after checking the temperature. When the incoming water is really cool in winter it can go as quickly as 20 minutes.[/quote]
I do this also. On my last batch, I did a full boil and used this same technique with frozen bottles in a storage bin instead of a bathtub. I was able to get the wort down to pitching temps in less than a half hour.
