You’ll forgive (and correct) me if I’m spelling it wrong. Back in [circa] the late 70’s early 80’s there was a drink mix called “Choco-Chill” (sic?). The only way I can describe it is as a chocolate Kool-Aid type drink mix. It wasn’t great, but due to my alergy to dairy products it was as close as I was ever going to get to chocolate milk.

My wife (of 25 years as of next week :)) says she doesn’t remember this stuff at all, though I seem to recall her buying it for me. So, I’m looking for some graphics of the packaging. Google has been no help, but perhaps I’m spelling the products name wrong. Any info/help is appreciated. Thanks in advance.

There’s a trademark registration for Nestle Choco Chill.

Damn trademark searches expire within minutes.
Go here, or if that expires here, and search for choco chill to see the drink’s logo.
There seems to be some sort of fruit-ice based choco chill available in the phillipines nowadays; likely not the same stuff.
