When canning? Seems that every canning thread I ever read people are still sterilizing jars. I equate that to wiping before you poop. I just don't make any sense. It's a waste of time, effort and energy. Anything that gets PC doesn't need the jars sterilized. Anything that gets BWB canned for 10 minutes or longer doesn't neeed to be sterilized. Grape juice in a quart jar only needs to be processed for 5 minute. I just find it easier to process it for 10 and be done with it. That and I usually do GJ in half gals anyway.
