He's been researching them online, I suspect here (http://www.idrink.com/starwars.html), although I tend to discount that page on the grounds that they can't spell Darth Vader. Also, if the Stormtrooper pairs Peppermint Schnapps and Jagermeister, it's definitely disgusting. And incorrect. A proper Stormtrooper cocktail should be mostly white and should cause you to miss anything you aim at.
