Hello all. I will be bottling my beer next week. In preparation for this I began collecting used bottles. Out of concern for cleanliness and sterilization I cleaned them by rinsing and then boiling them in water. Then I was going to run them through the dishwasher and sanitize them on bottling day. Am I going to far with the boiling bit? Can boiling them weaken the glass and cause breakage? Thanks for your input.
