Default How do you Chill your wort from 75 to pitching temperature?

Eventually my tap water can only cool my wort down so much, especially during the summer months. Usually I just drop my carboy w/ wort into the fridge, let it sit, and then pitch the yeast once it's cooled down to pitching temp. But this time I'm thinking about doing something new -- what do ya'll do?

I use a rubbermaid tub filled with ice water, and hook up a pond pump and pump the ice water into the chiller, and have it recirc back into the tub. It works great, you just have to be patient and get the temp down before you start using the ice water, otherwise the hot water will melt the ice, and you will be left with warm water.

I do partial boils, so I just put some of my bottled top-up water in the fridge. That gets it right down into the 60's with just a few liters.

+1 with cooler and ice water with pump, i let tap water take me to about 85 degrees or so then switch my "Y" valve to the ice water tank and let that take the rest of the way to 70 or whatever pitch temp you want. works great and fast

Same problem here - 80+ degree ground water in the summer months. I used to use an after-chiller submerged in ice water in the summer months, but I grew tired of purchasing large bags of ice and the lowest temperature I could obtain was ~70F.

I now do the same thing you do - drop the temp to ~80F and let it sit in my converted upright freezer for 30 minutes to an hour to reach the target pitching temperature (65F - 70F).

Sorry, no new suggestions...

Last summer I used a pond pump to recirc ice water through the chiller to get it down. So far this year I have just chilled it as low as I can go (around 85*F right now since it's about 100*F outside) and put it in the fermentation chamber with lots of ice packs. It takes about 2-3 hours to get down to pitching temp, which suits me just fine. As the ground water temp continues to rise in July and August I'll probably end up going back to the pond pump method but it is a pain to have to go buy ice.

I'm just asking out of curiosity here...is bottled water safe to just mix with wort? Does it have to be boiled first or have you had good experience just opening and adding?

Apologies for hijacking!

I have had no problems using bottled top off water as of yet. I now do full boils so I don't top off much anymore. YMMV.

If I get my wort down below 80, I'll go ahead and pitch and then toss into the fermentation fridge. Today though, my CFC only got it down to 84 b/c it's so hot outside, so about halfway through transfer to my bucket, I put it in a trash can with some ice and water while it continued into the fermenter and by the time transfer was complete, the wort was at 73. Good enough in my book.

Wouldn't a pre-chiller achieve the same goal without so many moving parts?
