It is safe to say that the KFC spice mix is very special for the brand. The original recipe is hidden in a vault in Louisville — and if you try really hard and trace the ingredients for the spice mix, you'll realize that two entirely different companies are involved in the process. Per The Daily Meal, Griffith Laboratories manages half the ingredients, while the rest is taken care of by McCormick.
The combination to the lock where the original recipe is hidden is something that's not widely known, either. To be precise, just one employee knows the code, while two others know the exact combination of herbs and are responsible for the super secret recipe (via Gizmodo).
While this is great for marketing and selling KFC as a brand, not everyone is impressed by the secrecy. A Redditor said that they don't care too much about the spice blend and wrote, "I like Kentucky Fried Chicken, because it's fried f****** chicken and that s**** is great, but it's not like the spices are so mind-blowing that the secret needs to be guarded at all costs."
