When a company wants to have their food labeled as a certified kosher food, they must follow these all the kosher rules and have the food properly inspected to gain the seal of approval. vomFASS Madison has over 60 products which carry Kosher certifications, including many of our fruit balsamics, our nut/seed oils and extra virgin olive oils and our spirits.
