Tap water temp.

[Hammy71]

I've seen a couple of vids on youtube where the person brewing and using a immersion or simple coppertube wort chiller say that the lowest they can can their wort is in the high 80's because of their tap water temp. Now I just finished cooling my wort to 110 degrees in less than 10 minutes. Of course it was a partial boil of about 2 1/2 gallons. So I checked my tap water temp and it is a steady 55 degrees (no wonder it took so long for my water bed to heat up !!) Is this better than average for a low temp. I have a well (that is over 300 ft deep....trust me...I've pulled the pump at least once and it's over 300 feet.) So....what's your tap water temp?

I think mine runs about 65. You ought to shoot for less than 90 in your beer. If using an immersion cooler, let it cool longer. If using a counterflow cooler, slow down the beer flow and/or run the water faster.

I poke a paperclip wire into my plastic out flow hose where it joins the counterflow copper tube. It sucks in air, thereby oxygenating the cool brew.

Well water doesn't fluctuate like city water drawn from above ground reseviors. My city water goes from about 85F in August to 48F January.
