Not all Parmesan uses animal rennet. While traditional Parmigiano-Reggiano, made according to Protected Designation of Origin (PDO) regulations, requires animal rennet, many producers outside of these strict guidelines offer Parmesan-style cheeses using vegetable or microbial rennet. These alternatives cater to vegetarians and those avoiding animal rennet for dietary reasons. To ensure you're getting a product that aligns with your preferences, look for labels indicating the type of rennet used or specific certifications catering to vegetarian diets.
