look up any word, like pussy:
The study of beer and beer-making, including the role particular ingredients play in the brewing process. A zythologist is a student and connoisseur of beer who possesses knowledge of ingredients, pouring techniques and beer pairings.

from Greek zythos (beer) and logos (study)
The waiter won’t know which beer to pair with a roasted rack of lamb. I’ve been studying zythology and I think you should have the lager.
