When I was a kid, soda came in 12-16oz & quart glass bottles.
And it stayed fizzy wa-a-a-ay longer than soda in cans or plastic bottles.
I absolutely never
buy a 2-liter bottle of soda (cheapest & always on sale!) because I have a glass or two & the rest of it goes flat before I get back to it. You can't re-seal it tight enough (it goes flat because it lacks pressure) & then it's garbage. I realize some folks don't mind drinking flat soda, but, to me, "soda" implies effervescence.
I was notorious for leaving half-drunk, open bottles standing around as a kid. BUT
....when you found them 3 days later, the soda would still be bubbly.
Doesn't happen with aluminum or plastic. And just what
is leaching out of that aluminum & plastic into your beverage?
Some rep at the Scweppe's booth at the Restaurant Show once explained it had to do with the way carbonation clings to glass as opposed to plastic/metal. I don't know if he knew what he was talking about, but, yeah...soda stays fizzy longer in glass.
I bought a bottle of Jarritos soda (in glass) a few days ago & left it open (habit) &, sure enough, 2 days later it was still bubbly. Very bubbly.
People don't really recycle aluminum & plastic...but pay .10 a bottle & they'd want their money back.
Deposit money was one of my main resources for gas money when I started driving (abd gas was .35 a gallon!)
Geez...I sound like my mother....
