Bottling day is tomorrow! I was going to try sanitizing my bottles in the dishwasher on a Drying cycle, but then realized I don't have a way to check the temperature inside to make sure it's hot enough. So I checked my How-to-Brew page and saw that I can sterilize the bottles if left in the oven for 60 minutes at 338 degrees F. For those of you who have done this, did you add aluminum foil over the tops before putting them in the oven, or after you took them out?
