Gillywater. It’s a drink in the wizarding world, but what is it? At the Harry Potter theme park, it’s just water. McGonagall orders some from Madame Rosmerta in the Three Broomsticks. She’s orders a small, so it seems like it’s probably more than just water. It’s probably not alcoholic. Does it have Gillyweed in it? Just a hint to get for the taste, but not give you gills and webbed toes?
I’m going to assume it’s a refreshing beverage with some green plant matter in it.
So, here it is! Fizzy water with cucumber and lime slices and mint leaves. Super refreshing and a good drink to serve at a Potter Party along side all the sweets.
Some super rad person out there made these labels for wizarding (and witching!) world beverages that you can print out and put on water or soda bottles. Or you can make your own label for a Pellegrino bottle like I did.
