[rant] Today I finished off my last Sour Apple Crush from my trip to Canada 6 months ago, eh? Had a November freshness date, but the bottles started going flat in October. My bottle today? hardly any carbonation at all, it might as well have been Sour Apple Juice! [/rant]
I hate plastic bottles too, man...for the same reason and an additional one. They don't really conduct the coldness of a soft drink the way glass does, or even a can. You are completely right.
I am still working on my two 12 packs of Fanta Citrus with a November expiration date. Still plenty of carbonation, although the taste isn't as strong as it originally was.
