OK so totally random post but I've been drinking coca cola from GLASS bottles, and it's amazing!

It tastes completely dif than the stuff in cans, and it doesn't go flat!!! Which I still can't figure out!

I can have a glass bottle of coke open and drink it 2 hours later and it's still fizzy! Stuff in cans is flat in like 45 minutes and tastes like syrup from hell. 😳 Can someone explain this to me???

BTW I'm not a pop drinker really anymore but I do have relapses 😎😏
