Origin & Lineage
Geographic Origin:
Cabai Kopay originates from Sumatra, Indonesia, a region known for its rich agricultural diversity and chili breeding traditions. The cultivar was developed by Syahrul Yondri, a farmer and field researcher who sought to create a pepper resistant to aphids and the yellow Gemini virus. Sumatra’s tropical climate, fertile volcanic soils, and high humidity provided ideal conditions for the selection and stabilization of this variety. Today, Cabai Kopay is grown across Indonesia and has been introduced to international seed networks, including South Africa and the United States.
Cultural Significance:
In Indonesian culinary culture, cabai (chili) is a foundational ingredient, used in sambals, stir-fries, soups, and marinades. Cabai Kopay, with its moderate heat and aromatic profile, is particularly suited to dishes that require warmth without overpowering spice. It is often used in home cooking, street food, and regional specialties such as “sambal goreng” and “ikan balado.” While not associated with ritual use, the cultivar reflects Indonesia’s deep-rooted relationship with chili peppers and its ongoing innovation in pest-resistant breeding.
Lineage / Hybridizer History:
Cabai Kopay was created in 2005 by Syahrul Yondri through home field research in Sumatra. His goal was to develop a chili variety that could withstand aphid infestations and viral attacks, particularly the yellow Gemini virus. The cultivar was selected for its hairy foliage, which may deter pests, and its low Brix level, which contributes to disease resistance. It was stabilized through open pollination and seed saving, and remains an heirloom variety with high productivity and consistent pod morphology.
Heat Profile
Scoville Rating (SHU):
Estimated between 10,000 and 30,000 SHU
Perceived Heat:
Medium (1,000 to 15,000 SHU)
Heat Characteristics:
Cabai Kopay delivers a gentle, warming heat that builds gradually and fades cleanly. The burn is concentrated near the seed cavity and inner walls, offering a satisfying sting without overwhelming the palate. When used fresh, the heat is immediate but manageable. When dried or roasted, the pungency intensifies slightly, adding depth to sauces and spice blends.
