Forget Cocoa Puffs. Taylor Jarvis is cuckoo for chocolate milk. “I drink it every day at lunch,” said Jarvis, 15, of Guilderland, a freshman at Notre Dame-Bishop Gibbons High School in Schenectady. “Pretty much every day at dinner. If I’m thirsty, I have a chocolate milk.” Those are cool and creamy words for dairy and chocolate producers. They appreciate customers like Jarvis and others who include one of dairy’s two most famous chocolate products in their daily diets. Teens and athletes may not scoop chocolate ice cream for dessert every day, but they are willing to chug liquid chocolate.
