Most traditional rennet is extracted from the stomachs of young calves, a by-product of veal production. This method does involve the killing of calves. However, there are vegetarian alternatives available, such as microbial rennet which is derived from fungi or bacteria, and genetically engineered rennet. For those concerned with animal welfare, seeking out cheeses made with these alternatives is a recommended practice.
