Grass Fed Beef Bone. 

Why Kettle & Fire Bone Broth? Unlike a standard broth or stock, bone broth uses 100% grass-fed and finished beef bones that we slow-simmer for 20+ hours. We're on a mission to bring back bone broth. Our bone broth is made with great ingredients and no preservatives. It's broth your great-grandmother would recognize and love. Nick and Justin. Founders, Kettle & Fire.
