I'm a huge soda fan and been drinking Coca-Cola for most of my life...then about 4 or 5 years ago Coke Zero came. It was cool, it came in my most favorite color scheme and tasted weird but nice the first time I tried it. Regular Coke here in the Philippines is made with real sugar instead of high fructose corn syrup, so that sweet-then-sour sugary aftertaste bugs me (not really sure about the US or other versions in different countries). And yes, most of the bottle caps in the picture were from 1.5L or 2L bottles that we've consumed the past year till now. :)
