All of the methods really allow you to only get close to the source water, no matter which it is ...
So, at the end of the day, here in Florida, you are either circulating ice water, putting your container in ice water, or pre-chilling the water source through ice water to get to pitching temp ...
The main reason I'm going to go balls out on worth chilling is to recoup time spent brewing, really ... that it's better for beer is also great, but mostly I need to be able to wrap up a brew session and get back to work ...
I am trying to get my setup built to allow me to do the me-intensive part (sparging and boiling and wort chilling) of brewing in ~2 hours, in hopes of being able to do it 2-3 x's/wk ...
I think it requires a 75 min boil to hit 2 hrs, so maybe I'll decide that 2.25 hrs is neeeded, but the point is the same ... quick!
Looks good.
