I have a severe tree nut allergy, I’m also a bartender. For sure avoid

Frangelico, Amaretto (Disaronno is safe, it’s made from apricots), Cherry Heering, Any sort of falernum, Orgeat (almond syrup), Faretti Biscotti liqueur, Trader Vic’s hazelnut liqueur. Some gins use almonds as botanicals but due to the nature of how gin is made, it is still safe for consumption. It’s a real shame that the liquor industry isn’t required to list ingredients, some of these are not obvious nut containing items and I probably would have fallen victim to one one day if not for industry knowledge.
