Understanding the Scoville Scale

The Scoville scale measures pepper heat intensity based on capsaicin concentration. Developed in 1912, it quantifies heat in Scoville Heat Units (SHU). Bell peppers sit at 0 SHU, the lowest possible rating, meaning they have zero heat. This makes them the perfect introduction to peppers for beginners or those avoiding spice.
