It just occurred to me that unlike Peppermint, Spearmint, and Doublemint, the flavor Wintergreen (or Winterfresh, depending on the product) doesn’t actually contain the word “mint.” I’m pretty sure it’s still a mint-based flavor, so I think that “mint” is implied subconsciously when we say “wint.” They could have just named it “Mintergreen” to avoid confusion, but that would sound silly.
