Corking in Jalapeno Peppers

explanation of corking and when to pick Jalapenos

Hot varieties of Peppers will change color as they ripen on the plant. Jalapeno’s usually turn red, and in some cases orange (orange spice). Red jalapeños tend to have a sweeter, slightly fruitier taste compared to green jalapeños. Additionally, they often have a more intense level of spiciness or heat.

In short season growing areas, Peppers may not have enough time to fully ripen and change color before the risk of frost returns. You may notice other changes in the appearance of Jalapeno’s that allow you to determine when they are ready to harvest. One of those changes is referred to as ‘Corking’

Corking is a term used to describe the appearance of thin, raised lines or cracks on the surface of a jalapeño pepper. These lines resemble the texture of cork, hence the term “corking.” Corking is a natural phenomenon that occurs as jalapeño peppers mature on the plant.

Corking is a great gauge as to when to harvest your jalapeño peppers. Once the peppers near maturation and the skin begins to show these raised lines, keep a close eye on them. Harvest the peppers anytime after corking appears, and before the first frost, for peak ripeness.
