@justin_danger_nunley: In 1935, Atlanta Rabbi Tobias Geffen became the only non-employee in history allowed to view the complete, exact secret formula for Coca-Cola. Why He Saw the Formula Kosher certification: Atlanta's Jewish community asked if the wildly popular drink complied with religious dietary laws. Ingredient inspection: Rabbi Tobias Geffen needed to see every single component to determine if it was kosher. The fix: He found non-kosher beef tallow glycerin and grain alcohol (forbidden during Passover). The result: Coca-Cola agreed to change the ingredients to vegetable-based substitutes so he would certify the drink.
