My first question has to do with water. A lot of the recipes I see call for heating the wort and adding it to the carboy, then add cold water to cool it down. I have untreated well water which potentially has little critters floating around in it. So far I've been lucky and have had good results from the beer I'm making but in the back of my mind I'm always worried if I go the cold-water route that I may be introducing something bad. Any thoughts? Thanks! Tod P.
