Appearance

Sourdough buds are typically medium-dense and shaped like golf balls or cones, exhibiting a sativa-hybrid structure. The calyxes stack tightly in a spiral pattern around a central stem, with pistils ranging from orange to tangerine. Trichomes form a frosted layer, giving the buds a glistening appearance, especially in high-terpene expressions. Leaf coloration can vary from lime to deep olive, sometimes displaying purple or plum streaks under cooler temperatures. Well-trimmed flowers have minimal sugar leaves, revealing thick, resinous heads.

Aroma & Flavor

The aroma of Sourdough is complex, combining the scent of warm sourdough crust with a lactic tang and underlying diesel vapor. Secondary notes can include toasted barley, vanilla cream, and herbal undertones like bay leaf and thyme, alongside earthy forest floor notes. On the palate, it delivers a tangy, sour initial taste that evolves into toasted grain, citrus peel, peppery spice, and diesel vapor, often rounded out by a creamy sweetness and a lingering mineral or vanilla finish.

Effects

Consumers often report an uplifting onset with Sourdough, leading to steady mid-run focus and functional clarity, making it suitable for daytime or late afternoon use. The experience typically concludes with a softening into comfortable physical calm. Many find it enhances creative drive while maintaining a clear head.

Terpenes & Cannabinoids

Lab results for Sourdough generally indicate high THC levels, commonly ranging from 20-27%, with some exceptional batches reaching up to 28%. CBD content is usually below 1%. Total terpene content often falls between 1.5% and 3.5%, with notable expressions contributing to its distinct aroma and flavor profile. Common terpenes associated with this cultivar include Myrcene, Limonene, Caryophyllene, and Linalool, contributing to its complex sensory experience.

Origins & Lineage

Sourdough emerged in the late 2010s, bred by artisan cultivators aiming to blend classic diesel genetics with dessert-forward cookie strains. It is commonly understood as a cross involving Sour Diesel and a dessert-dominant line, such as those from the Cookies or OGKB families. This lineage imparts both the tangy, fuel-like characteristics of diesel and the creamy, sweet notes of cookie cultivars.

Growing

Growers may observe variations in Sourdough phenotypes. Diesel-dominant versions might exhibit more aggressive stretching and a slightly later finish, while cookie-leaning types often show tighter internodes and denser bud stacking. Foliage can range from deep olive to lime green, with potential for purple highlights under cool conditions. The strain is appreciated for its terpene modularity, allowing for a rich bouquet that retains the diesel core.
