Affiliate Marketing Secrets

I have a very serious nut allergy (peanuts and tree nuts), and take great care with everything I eat, but I avoid drinks like Malibu and Morgan’s Spiced because of the ‘secret spices’ or ‘clever recipe’ type marketing. I know the obvious ones like Amaretto contain nuts, but others I’m not so sure. Does anyone know of any websites or anywhere to find information on what drinks do and don’t have nuts/allergens in them? It would be great to find out. Thanks a lot for your help.
