Appearance

Sourdough typically presents dense, compact flowers, often described as golf-ball or spear-shaped. These buds feature a high calyx-to-leaf ratio and are frequently covered in a frosted layer of abundant glandular trichomes, giving them a sugar-dusted appearance. Pistils commonly range from apricot to rust-orange, contrasting with olive to forest-green bracts. Some phenotypes may display faint plum or lavender hues, particularly in cooler growing conditions or late in the flowering cycle. The structure often reflects a hybrid ideal, with sturdy growth and dense bud formation.

Aroma & Flavor

The aroma of Sourdough is characterized by a prominent diesel-forward scent layered with a tangy, bready warmth, often described as a fusion of fuel and bakery notes. Underlying this are hints of citrus zest, faint vanilla, and toasted grain. Upon grinding, the aroma intensifies, sharpening the sour edge and brightening the citrus notes, with a subtle peppery-spice and woody undertone. The flavor mirrors the aroma, starting with sharp diesel and citrus-tang on the inhale, followed by a bready, toasted finish with notes of nuttiness and a hint of vanilla-sugar on the exhale. Lower temperatures tend to emphasize citrus and bakery notes, while higher temperatures bring out more pepper and gas.

Effects

Sourdough is generally reported to provide a cerebral and energetic experience. Users often describe effects that are uplifting and conducive to creativity. The strain's hybrid nature suggests a balanced influence, offering a stimulating mental uplift without being overly sedating.

Terpenes & Cannabinoids

Sourdough typically exhibits a high THC content, frequently testing between 18% and 26%, with some exceptional phenotypes reaching higher percentages. CBD levels are usually minimal, below 1%. The terpene profile often reflects its genetic influences, with caryophyllene, myrcene, and limonene commonly being dominant, contributing to its spicy, gassy, and citrusy characteristics. Other terpenes like humulene and linalool may add herbal, woody, or floral nuances, contributing to the complex aroma and flavor profile. Minor cannabinoids such as CBG may also be present in varying amounts.

Origins & Lineage

Sourdough is a modern craft cultivar whose specific lineage can vary by breeder, as it is not a single protected strain. However, common breeding theories suggest a genetic foundation involving Sour Diesel on one side, contributing its characteristic fuel aroma and sour notes. The other parent is often a Cookies-descendant (like GSC or Gelato) or an OG Kush varietal, which imparts the doughy, nutty, and bread-crust aromatics. This combination aims to balance the energizing qualities of Sour Diesel with the smoother mouthfeel and structure associated with Cookies and OG strains.

Growing

While specific cultivation details vary by breeder, Sourdough phenotypes generally exhibit hybrid vigor, often developing medium-stout frames with strong apical dominance. Growers often select for traits such as dense calyx stacking, pronounced fuel aromatics, and the unique tangy aroma. The strain is known for producing dense flowers with a high calyx-to-leaf ratio and abundant trichome coverage, indicative of robust resin production. Proper curing is essential to preserve its complex terpene profile and moisture content.
