Newbie here, only one batch recently bottled and 3 still fermenting.
A buddy just gave me 2 - 30' coils of 3/8" copper. I just bought a keggle and am converting a cooler to a mash tun to prepare for all grain brewing.
I am thinking of using this copper to make a counter flow chiller using this tutorial in the wiki.
And also make a pre-chiller using the basic immersion chiller design in a 5 gallon bucket with ice.
Anything you would do different with 2 - 30' coils of coppper?
