When should a beverage name be capitalized?
If the beverage is a brand name or a unique recipe title or includes a proper noun, capitalize it:
Frappuccino (a coinage trademarked by Starbucks)
Arnold Palmer (named after a person)
Long Island iced tea (includes a place-name)
But when the drink is a generic term, lowercase it:
Sometimes drink names composed of proper nouns can be lowercased:
Manhattan or manhattan
