Yoohoo is a chocolate flavored drink. Yoohoo should always be served cold, and should be agitated liberally before opening the container. Yoohoo tastes very good. It is not carbonated, so it lends itself well to chugging. Yoohoo containers are always sold slightly underfilled (11 ounces per can, vs. the standard 12); this is not a marketing scam. The extra space in the container allows the drink to be agitated effectively.
