Old Red Sour

Old Red Sour is a hybrid cannabis strain with up to 24.0% THC, known for its euphoric effects and citrus and diesel flavor profile.

Old Red Sour is a relatively rare cannabis strain believed to be a phenotype of the classic Sour Diesel lineage, though its exact genetic origins remain somewhat obscure within cannabis cultivation circles. The strain appears to have emerged in the early 2000s on the West Coast of the United States, with some sources suggesting it was developed by underground breeders seeking to preserve older Sour Diesel genetics before commercial breeding trends shifted. The name 'Old Red' likely refers to the distinctive reddish or purplish hues that can develop in the buds under certain growing conditions, particularly when exposed to cooler temperatures during the flowering phase.

Visually, Old Red Sour plants typically produce medium to large-sized buds with a dense, elongated structure characteristic of Diesel varieties. The flowers often display a vibrant green base color with fiery orange pistils and occasional purple or reddish pigmentation in the leaves and calyxes. The buds are usually coated in a generous layer of frosty trichomes, giving them a shimmering appearance. The aroma profile is complex and pungent, combining the classic fuel-like diesel scent with sour citrus notes and subtle earthy undertones, creating a distinctive olfactory experience that many enthusiasts find appealing.

While not as widely documented as mainstream Sour Diesel varieties, Old Red Sour has maintained a cult following among certain cannabis connoisseurs who appreciate its balanced effects and unique terpene profile. The strain is considered somewhat rare in commercial markets, with most available material coming from small-scale growers or seed banks specializing in heritage genetics. Its relative obscurity means that consistent quality and genetic stability can vary between different sources, making it a strain that experienced users often seek out from trusted cultivators.
