My parents, who didn't forbid soda pop but never had it in the house either, used to call Yoo-hoo "chocolate water." They said if you want chocolate milk, we'll mix up some. They didn't understand the pull of a branded cold glass bottle in the grocery store. Or maybe they did. Anyway, I don't recall ever drinking a Yoo-hoo, despite the fact that it's very popular where I am from. Or at least it was until Mountain Dew was crowned as the top drink.
The main idea behind Yoo-hoo was that it resembled chocolate milk without having to be refrigerated. Sure, stores put it in the cold drink section, but that was right before you bought it. That eliminated the possibility of making it with fresh milk. Yet people loved it- from baseball players to the pope. Weird History Food goes through the history of Yoo-hoo and reveals what's really in that bottle. -via Geeks Are Sexy
Kind of nostalgic, but as for flavor, it's a step down from every other ready to drink milk-based shelf-stable chocolate drink... Like Nesquik, Carnation breakfast, Nutrament, or probably any brand of UHT chocolate milk.
