Ok, so at this point in time I do not want to spend the time or $ to make a wort cooler. Last batch I made, I just cooled outside until ready (still took like 3 hrs, not cool because I think I got some off flavors from that). So I am wondering, is it ok to use the Alton Brown method and mix wort with ice to cool it down & dilute? Or I will just take a big rubbermaid tub and make an ice bath for boil pot and stir for awhile. So I guess the root question is how sanitary is ice from a grocery store?
