I recent got ahold of a 50’x 1/2” od coil of copper tubing and was thinking of making a new wort chiller out of it. My old chiller was great in my 3 and 5 gal pots but I now also have a 9 and 10 gal pots which are taller and wider.... so obviously I need a taller chiller.... does anyone else have experience with 1/2” coils? Should I use the full 50’ or half or more of it?
