Yes, you can keep any fats in the freezer, if you have the room. But….I wouldn’t put glass bottles of oil in freezer. Not sure if they will even freeze solid but don’t chance it. We have kept olive oil in the refrigerator tho. That works but I’ve heard it’s not pure olive oil if it gets clumps in it. Meh, clumps go away when you set it out at room temperature.
It’s air that does the damage too. Don’t let air or light touch your oils.
