My dishwasher has a sanitation cycle that I've used to sanitize my bottles & it works. I've always rinsed the bottles under cold tap water just to cool them down a bit. Is that necessary? Will the heat give my beer off-flavors?
Ive stopped using star San on bottles for the last six batches. I use the dishwasher with a shot of vinegar and high, bacteria killing temperature. I don't bother cooling the bottles and I've had excellent results.
