Muscadet

According to Wikipedia: "While most appellation d'origine contrôlée wines are named after their growing region, or in Alsace after their variety, the name Muscadet refers to an alleged characteristic of the wine produced by the melon grape variety: vin qui a un goût musqué (wine with a musk–like taste). However, according to wine expert Tom Stevenson, Muscadet wines do not have much, if any, muskiness or Muscat–like flavors or aromas."

Muscadet isn't actually made from the Muscat grape. According to Wikipedia (again), it's made from the Melon de Bourgogne, often referred to simply as melon.
