What kind of ale or lager is it? Is it sweet, bitter, malty or hoppy? Should it be served cold or hot? And what glassware do you use?
These are typical questions from amateur fans. In case they're shy, answer their questions with a big, descriptive label. Add some details, like a personalized design or some rich copy about your new chocolate stout, and maybe they'll be talking to strangers about all your other delicious beers.
