Quinn and Tessa's aromatherapy store "Satchel Serafina" is named for Serafina Pekkala, the witch in The Golden Compass (2007) - and is clearly a parody of Catland Books, Brooklyn's actual premiere metaphysical emporium.
Nandor, at one point just before the "extraction", says "It's for wine, isn't it". The instrument one of the witches is holding is indeed a large lever-operated corkscrew for use in restaurants and bars.
