Diesel refers colloquially to any cannabis strain expressing a uniquely pungent, aromatic flavor and odor profile reminiscent of petrol, diesel fuel or chemical solvents. The original source of this notoriously stinky bouquet was an enigmatic strain called Sour Diesel that rose to prominence in New York City during the 1990s, essentially establishing the diesel category as an iconic flavor profile unto itself that growers still chase today. Other notable diesel strains followed in Sour Diesel's footsteps including NYC Diesel, Strawberry Diesel, Diesel Dough, Cherry Diesel, Blackberry Diesel, and Jet Fuel.
The quintessential diesel stench comes from an intricate cocktail blend of sesquiterpene aromatics - primarily myrcene and caryophyllene working in concert to give these cultivars their signature gassy, chemical-like petroleum funk capable of overpowering entire rooms. The sheer volume and concentration of terpenes needed to achieve the true diesel odor is also a clear indication of the fuel strains' generally copious resin content.
Diesel varieties also have a well-deserved reputation for being soaringly potent while also providing energizing, thought-provoking psychoactive effects. The sour, pungent chemical diesel aroma itself has clearly become forever cemented as an instantly recognizable olfactory experience within the diverse spectrum of cannabis strain varieties. Diesel's enduring popularity years later stems directly from its memorable flavors and invigorating, hard-hitting highs.
