Tallow is rendered beef fat. Our grass fed tallow is sourced from US Farmers. Tallow is rich in Vitamins A, D, E, K, antioxidants and essential fatty acids. It is not produced outside of the US and then shipped into the US like a lot of gass fed beef is. Our tallow is rendered using the wet rendering process (salt and water) to remove impurities and beefy smell while preserving the amazing nutrients. It is a long process but so worth it! It is made in small batches in Lake Forest, IL.
