Just got thru cooling 5 gal wort. Took 1/2 hr to drop temp from 134 deg F to 70 deg F for pitching yeast and had to use ice bath.
My cooler is 20 feet of copper tubing, 5/8" OD / 1/2" ID. Many commercial immersion coolers are 3/8" x 25 feet. Don't know if the 3/8" is OD or ID.
To save money I bought the above larger diameter but shorter copper tubing figuring the cooling ability would be about the same.
The tubing has 6 coils, 8" in diameter and 6.5" tall. I plan to separate the coils to 12" tall to increase surface area contact (I think) with the wort. Can not change diameter as copper will kink.
Questions: Is a 1/2 hr an expected time to drop temp 64 deg? Some post much faster temp drop times.
