Has Snapple always been 16 oz for the individual size bottle? The new skinnier 16 oz plastic one *feels* smaller to me than the fatter old glass bottle and I'm trying to remember if they were 18 or 20 oz and this is shrinkflation or just my imagination?

The glass bottles were 16 fl oz...

Yes,no change in quantity. The plastic sure doesn't retain the cold temp as well either..

Snapple sodas didn’t come in those size/style bottles at all, but I know you don’t mean that originally. They stopped making them ages ago and that was a shame.
