427: Original Recipe
Summary
Ira Glass investigates the mystery of Coca-Cola’s secret formula after discovering a 1979 newspaper clipping containing a recipe that matches documents in the company’s own archives. The team attempts to recreate the drink using modern ingredients and flavor experts, finding that while it closely resembles Coke, it lacks the specific "bite" of the modern beverage. The segment concludes with a taste test where most participants prefer the homemade version, highlighting that the brand’s power lies in marketing rather than an uncrackable secret.
