I see a ton of comments here hating on nostalgic people, with no actual nostalgic people in sight yet.
Personally I don't care if a pouched drink exists or not, but if they are no longer producing pouched drinks they should probably retire the brand.
Do you remember what a CapriSun tastes like? It's somewhere between an extremely-artificially flavored "juice" concentrate and a "fruit flavored" drink like Kool-Aid. The whole appeal was the packaging.
This is absolutely reeks of a bullshit "OMG the sky must be falling for you" condescending article from an older generation that thinks younger nostalgia is silly. I wouldn't give this article any more credence than a boomer yelling "Avocado Toast!" at you when you're enjoying a nice brunch. It's just needlessly sensationalist shit stirring.
