Naturally smoked. US inspected and passed by Department of Agriculture. Since 1969. To create the unique salty-sweet flavor in my teriyaki beef jerky, I marinate lean beef strips in soy sauce and apple cider vinegar, season the cuts with my own mix of spices, then smoke them with real wood until they're tender, juicy, and delicious. You deserve the best, eat Old Trapper. - T.O. Trapper, The Old Trapper. Visit us online at oldtrapper.com. Made in the USA.
