About

Chile de Agua peppers are conical to slightly curved pods averaging 7-12 cm in length and 2-3 cm in diameter, tapering to a pointed tip. The waxy, glossy skin is smooth and slightly wavy, ripening from pale green through yellow and orange to a vibrant red when fully mature. The flesh is semi-thick, crisp, and aqueous with a pale green to white interior surrounding cream-colored, round, flat seeds. Plants are bushy and low-growing, reaching 2-3 feet tall, with fruits that grow erect and point upward. The flavor is complex, blending herbal, fruity, sweet, and sour notes with moderate spice; when roasted, it develops an almost buttery quality alongside a tart tomatillo-like tang. Heat is concentrated in the ribs and seeds. This heirloom is becoming rarer in its native region as farmers shift to more profitable varieties like Guajillo, though seeds are now available for home gardeners.

Backstory

This rare heirloom chile has been cultivated for over 300 years in the Valles Centrales of Oaxaca, Mexico, as part of the traditional milpa farming system with corn, beans, and squash. Its name may refer to its preference for water or the moisture it releases when roasted. Production is declining locally as farmers prefer higher-yielding varieties like Guajillo, increasing the value of authentic seeds for preservation and home growing.
