i know there are a lot of threads out there on this, but didn't see the answers to my questions. i'm planning on making a DIY wort chiller, similar to this one:
-do i need to get a certain type of copper tubing or will any type due? i want to make sure i don't get the wrong thing and end up with something that will make me sick, or even worse, give off flavors
-which is better for sanitizing it before use: boiling with the wort for 15 minutes or using star san on it?
thanks a bunch!
