Golden Cayenne Chile Pepper. 30,000 - 50,000 Scoville Units. Capsicum annuum. If you like cayenne peppers, you’re going to love their golden cousin. Although similar to the traditional cayenne chili pepper, there are a few differences. Where traditional cayenne fruits are wrinkled and skinny, golden cayenne peppers tend to be larger with smooth skin. This hot pepper develops beautiful, smooth-skinned golden peppers that add eye appeal to the garden, and gets hotter as it grows larger.
