The Chile de árbol is a small and potent Mexican chili pepper also known as bird's beak chile and rat's tail chile. These chilis are about 2 to 3 inches (5.1 to 7.6 cm) long, and 1⁄4 to 3⁄8 inch (0.64 to 0.95 cm) in diameter. Their heat index is between 15,000 and 30,000 Scoville units. The peppers are a bright red color when mature.[1] Chile de árbol peppers can be found fresh, dried, or powdered.[2] As dried chiles, they are often used to decorate wreaths because they do not lose their red color after dehydration.
