Sour Dubble is a modern hybrid-indica cultivar with an undocumented lineage, as its precise parentage remains unknown. This strain is credited to the American cannabis community, where it established a reputation for reliability and vigor throughout the modern era of selective breeding. Cultivators categorize the plant as moderately difficult to grow, though it performs well in both indoor and outdoor environments. With a flowering cycle of approximately 58 days, the strain is valued for its capacity to produce a high yield.

The chemical profile of Sour Dubble is defined by its primary concentration of myrcene, followed by caryophyllene and pinene. These terpenes contribute to a distinct aromatic complexity, characterized by the interplay between the earthy base of the myrcene and the spicy notes of the caryophyllene, rounded out by the subtle aromatic clarity provided by the pinene. This specific terpene hierarchy informs the sensory nuances of the flower, which is strictly THC-dominant.

The effects of Sour Dubble are consistently reported as relaxed and focused. These properties make the strain a functional choice for those seeking to alleviate pain, manage stress, or facilitate sleep. As an influential genetic component in the modern market, the strain has served as the foundation for a wide array of notable offspring including Dubble Banana Mango Haze, Sour Banana Dubb, Sans Souci, Key Lime Pie x Sour Dubble, Pink Banana Crush, Riddle MAC, Papaya Stank, Sour Dubble x Querkle, Sour Drippz, Atomic Sour, Birdshot, and Cherry Heads.
