My brother-in-law who runs a small pub in North Norway visited us early this month. He brews a very good IPA so I bought a few bottles for him to taste. I don't normally buy bottles of beer but we were very surprised to find one brewers bottle appeared to have a vertical join and was folded from the bottom up. I asked the brewers concerned about this and also passed complements on the brew but have had no response. Any one know enough about glassmaking to comment please?
Pretty well all beer bottles have that if you look, the molten glass is dropped/blown into a mould in two halves, where the mould meets is the line, if I remember my Playschool trips through the round window :-)

Thank you for your answers; they make mechanical sense. I have looked at other bottles including wine bottles and on close examination they do have a very faint seam. The Greene King bottles must have been made with a worn mould as the joint was very obvious however they didn't leak.
