For nostalgic reasons, I believe that soda still tastes the best in a glass bottle.
There must be this certain retro feeling that you get from certain things. Whether it's an old hockey jersey, or an old school video game, it always seems to awaken the child in you, and it makes you feel super. It's what I get from sodas. I'd love to get a hold of a coke in a glass bottle. Soda in this kind of fashion just feels right to me. Cranking it open like a European beer bottle, and taking a sip of it as if you needed to cool down badly on a hot summer day.
Old school rocks!
