I'm having what's known as "Cotton Candy Grapes," seasonal California grapes which are almost surely bred for maximum sweetness (note the other bizarre types of grapes on their web page) - they really do have a confectionary quality to them, while being quite large and extremely succulent. There's nothing "gross" about them; they're very good, although the extreme, high-toned sweetness may throw some people off at first.
