Shake all but IPA, strain into champagne flute or smallish wine glass. Top with IPA, express peel, and use it to stir once as you drop it in.
Smaller glass size may mean less IPA (still tastes great with as little as 2 oz.), just make sure you don't exceed 3 oz.
French 75 variation built around the grapefruity nose of the Dogfish Head 60 Minute IPA... I'm not 100% happy with the cocktail's name. Open to suggestions.
