Sourdough Rvr
Sour Diesel × Cookies/Gelato
Sourdough Rvr typically refers to a specific phenotype of the Sourdough cultivar associated with the RVR designation, indicating a curated selection by a provider. This hybrid is recognized for its complex aroma and flavor, blending sour and gassy notes with warm, bakery-like undertones. It is generally considered a contemporary hybrid with mid-to-high THC potency.
Appearance
Sourdough Rvr usually presents dense, medium-sized flowers characterized by a high calyx-to-leaf ratio and a layered, knobby structure. The buds often display olive to forest-green coloration, sometimes with purple hues if exposed to cooler nighttime temperatures late in flowering. They are typically adorned with orange to apricot pistils and a prominent, sugar-like coating of trichomes.
Well-cultivated examples exhibit heavy resin coverage with glandular trichome heads that remain intact when handled carefully. The flowers can be golf-ball to torpedo-shaped, and maintaining controlled environmental conditions is key to preventing loose tips and ensuring a tidy appearance, especially during late flowering stages.
Aroma & Flavor
The aroma of Sourdough Rvr is layered, featuring prominent sourness, tart citrus notes, and a subtle yeasty warmth reminiscent of freshly baked dough. A distinct gas or fuel-like scent, often associated with volatile sulfur compounds, is also commonly present. These complex aromatic qualities are enhanced by proper curing, which helps to meld the sour, bready, and gassy elements.
The flavor profile mirrors the aroma, offering a bright, tangy inhale with a lemon-peel or green apple initial taste. The exhale often reveals warm, toasty grain, anise, and white pepper notes. Vaporization at moderate temperatures can accentuate the dough and spice characteristics, while combustion tends to highlight the sour brightness.
Effects
Consumers report that Sourdough Rvr can inspire creativity, making it a suitable choice for artistic or mentally engaging tasks. The strain is often described as providing a balance between daytime clarity and evening relaxation, suggesting a nuanced effect profile that may not be overly sedating.
Terpenes & Cannabinoids
While specific terpene profiles can vary, common terpenes associated with Sourdough phenotypes include Myrcene, Limonene, Caryophyllene, Linalool, Humulene, and Terpinolene. These contribute to the strain's distinctive aroma and flavor characteristics, such as citrus, diesel, floral, herbal, and peppery notes. Limonene and Caryophyllene are often noted as dominant, supporting the hybrid's gassy and bakery-like qualities.
Potency for Sourdough Rvr typically falls within the mid-to-high THC range, generally testing between 18% and 26%, with some batches potentially exceeding this. CBD content is usually negligible, often below 0.5% or under the reporting threshold. Total cannabinoid percentages commonly range from 20% to 30%.
Growing
Phenotype hunts for Sourdough Rvr likely involve selecting a mother plant from a large number of germinated seeds to stabilize desired traits. This cultivar is expected to have moderate stretch and a flowering time of approximately 63–70 days. Yielding phenotypes often develop dense, well-formed colas.
Maintaining controlled environmental parameters is crucial for optimal growth and bud quality, particularly to avoid issues like loose flower tips. The plant generally responds well to both hand and light machine trimming, provided care is taken to preserve trichome integrity. Proper drying and curing, typically over 10–14 days at around 60°F/60% RH, are essential for preserving terpene content and achieving the desired aromatic and flavor profile.
Origins & Lineage
The Sourdough flavor family emerged from breeders crossing classic sour/diesel genetics with dessert-forward strains, gaining popularity in the 2010s. The Sourdough Rvr designation specifically points to a curated cut of the Sourdough profile by a provider using the RVR tag, often representing a house phenotype or regional release rather than a distinct genetic. The RVR tag suggests an intentional selection process aimed at achieving consistent flavor and chemotype.
A common genetic hypothesis for Sourdough suggests a lineage involving a Sour Diesel-like parent crossed with a Cookies or Gelato-like strain. This combination is thought to account for the simultaneous presence of pungent fuel, citrus-sour tang, and warm bakery notes. Without specific breeder notes, exact parentage is inferred based on the resulting chemotype and aroma characteristics.
