100 Percent Grass Fed Beef The same premium cuts of Grass Fed Beef we use for our Biltong are coarsely ground and seasoned with just 4 spices for a naturally bold flavor. The mix is then carefully hand stuffed into a casing and air dried for up to seven days. We use no fillers, no gluten, no soy, and no sugar. The result is a delicious, high protein beef stick that makes the ideal road trip or adventure snack. Find out for yourself why Droewors is the new standard for beef sticks.
