The Cheongyang chili pepper is a hot cultivar of Capsicum annuum cultivated primarily in Korea. It is prized for a sharp, lingering heat combined with a fruity pepper flavor, and appears in markets and household kitchens across the country. Fruits are typically harvested when green or allowed to ripen to red, and they are used fresh, dried, or preserved.

Characteristics

Cheongyang peppers are medium-sized, elongated pods with thin walls and a pointed tip. Their heat level is notable for the cultivar: many samples measure roughly 10,000–23,000 Scoville heat units, placing them well above common mild peppers but below the very hottest varieties. The cultivar was created as an improved strain combining traits from other peppers, so it tends to produce reliably high capsaicin content and consistent fruiting.

  • Species and type: Capsicum annuum.
  • Parentage: developed from crosses involving Thai peppers and local Jeju varieties; these relationships link it to both Thai and Jeju chili traditions.
  • Heat: commonly around 10,000–23,000 SHU, hotter than a typical jalapeño but milder than cayenne or bird's eye chilies.

History and development

The modern Cheongyang pepper emerged through deliberate breeding in the late 20th century. It was developed in 1983 by Dr. Il‑ung Yoo as a genetically improved strain aimed at combining heat, flavor, and suitable agronomic traits for Korean conditions. Its name reflects regional roots: it blends the names of two counties, Cheongsong and Yeongyang, acknowledging the areas involved in its development and early cultivation.

Uses and culinary importance

In Korean cuisine the Cheongyang pepper is valued for bringing pronounced spiciness without overwhelming other flavors. It appears in kimchi, stews, marinades, spicy sauces, and as a raw garnish. Because it offers a balance of heat and flavor, cooks often prefer it when they want a clean, peppery bite rather than the sharper, fruitier burn of some other varieties.

  • Common applications: kimchi, gochujang-style sauces, soups, pickles, and fresh slicing for banchan.
  • Handling tips: wear gloves when cutting large quantities to avoid skin or eye irritation; remove seeds and membranes to reduce heat.
  • Substitutes: use other medium-hot peppers if unavailable, but expect flavor and heat differences.

Beyond the kitchen, Cheongyang peppers are part of regional agriculture and seed-breeding programs focused on yield and disease resistance. They are sold fresh at markets, offered as dried flakes, and sometimes preserved in oil or brine. For those comparing heat, the Cheongyang sits comfortably between common household hot peppers and the very hot tropical types, making it a versatile option for home cooks and professional chefs alike.
