Double Black
Black Domina
Double Black is a deeply indica-leaning cultivar celebrated for its dark coloration, incense-like aroma, and profoundly relaxing effects. Often described as a refined expression of classic Afghan heritage, it is favored for its dense resin production and sedative qualities.
Appearance
True to its name, Double Black can display dramatic purple to near-black calyxes when exposed to cooler nighttime temperatures late in its flowering cycle. Without this temperature drop, flowers typically cure to a deep olive-brown-green, often with charcoal-colored sugar leaves. The buds are generally compact and dense, resembling golf balls or eggs, with tightly stacked calyxes and minimal foxtailing. Abundant trichome coverage gives the flowers a frosty appearance against their dark backdrop, complemented by copper or pumpkin-orange pistils.
The calyx-to-leaf ratio is usually favorable, contributing to reasonable manicuring times and good yield preservation post-trim. Double Black flowers often feel heavier than their appearance suggests due to dense internodal packing. Properly cured, the buds possess a firm yet springy texture, snapping rather than crumbling, indicative of optimal moisture content. Breaking open the buds reveals lighter green interiors and a release of volatile aromatics, suggesting good terpene retention.
Aroma & Flavor
The aroma of Double Black is characterized by a dominant profile of black pepper, clove, and earthy incense, often underscored by subtle dark fruit notes. The initial aroma typically presents spicy notes, followed by herbal and hoppy undertones. A warm, musky scent, reminiscent of a forest floor, often provides a grounding base. Secondary aromatic nuances can include hints of anise, fennel, cocoa nibs, or even faint espresso, with cooler finishes sometimes revealing a subtle blackberry or dried plum facet.
The flavor profile mirrors the aroma, beginning with a peppery sensation that tingles the palate and leaves a lingering taste. Inhaling may reveal a dry, cocoa-dust-like texture, with undertones of cedar and charred oak. Exhalations often bring forth notes of clove, star anise, and a mild, bitter-herbal finish. Vaporizing at lower temperatures tends to emphasize sweet earth, dark chocolate, and faint berry notes, while higher temperatures amplify the spicy and woody characteristics.
Effects
Double Black is primarily recognized for its profoundly relaxing body effects, making it an ideal choice for evening use or unwinding after a long day. Its indica-dominant nature typically leads to a calming sensation that can promote a sense of tranquility and physical ease. Consumers often report a significant couch-lock effect, encouraging a sedentary and relaxed state.
This strain is well-suited for quiet nights, pairing well with activities like watching movies or simply resting. The deeply sedative qualities make it a popular option for those seeking to de-stress and achieve a state of deep relaxation. Its effects are generally consistent with classic indica profiles, focusing on physical comfort and mental calmness.
Terpenes & Cannabinoids
Double Black typically exhibits a THC-dominant cannabinoid profile with minimal CBD content. Verified samples with similar lineage often show total THC levels ranging from 18% to 24%, with a common median around 20%. CBD levels are generally below 0.5%, frequently not detectable in competitive modern cultivars. The terpene profile is often noted for its spicy and earthy characteristics, with Myrcene, Caryophyllene, and Humulene frequently cited as dominant contributors. Limonene and Linalool may also be present, adding complexity to the overall aromatic and potential therapeutic profile.
The specific terpene composition, including Myrcene, Caryophyllene, Humulene, Limonene, and Linalool, plays a significant role in the perceived effects and overall experience of Double Black. Caryophyllene and Humulene are often associated with the strain's signature peppery, spicy, and herbal notes. Myrcene contributes a warm, musky undertone, while Limonene can add citrus nuances and Linalool floral hints. The balance and concentration of these terpenes, alongside cannabinoids, are believed to influence the strain's potency and characteristic effects beyond THC percentage alone.
Growing
Double Black is favored by growers for its reliable structure, short flowering times, and the potential for striking dark coloration when environmental conditions are optimized. It is known for producing dense resin, making it suitable for both flower and concentrate production. The plant structure is typically compact with tight internodes, simplifying canopy management and harvest planning, especially in scaled operations.
The strain thrives in Mediterranean climates and is well-suited for indoor cultivation with controlled environment agriculture. It is noted for its ability to produce dense indica colas and high capitate-stalked trichome density, which is advantageous for solventless extraction methods. Breeders often aim to shorten flowering times and enhance its visual and aromatic traits through selective breeding and backcrossing.
Origins and Lineage
Double Black is widely considered a reinforced backcross of Black Domina, a European indica strain developed in the 1990s. Black Domina itself is believed to be a composite of multiple Afghan-centric landraces, including Afghan, Ortega, Northern Lights, and Hash Plant. This lineage emphasizes indica traits such as resin production, compact growth, and sedative effects.
Breeders have focused on doubling down on the desirable traits of Black Domina, such as dark coloration, spicy aromatics, and sedative qualities, while also aiming to shorten flowering times and increase uniformity. This selective breeding process aims to reduce undesirable outlier traits and concentrate the phenotype towards a consistent profile, reinforcing its heavy indica heritage.
