I noticed when bottling my first batch this past weekend that Harp bottles wouldn't hold the cap likle hte other bottles - like Sam Adams. Are there different sizes? I couldn't use the Harps because they were crooked on the bottle and actually leaked a small bit. My neighbor gave me a couple 6 packs of Harp bottles which I am consdering throwing into the recycler. I also noticed that the Corona top was similar to the Harp. What gives?
