Let’s speak about Sour Diesel, the legendary strain that every single cannabis enthusiast worldwide has attempted at least when.

Sour D is frequently described as a sativa-dominant strain whose origins date back as far as the 1990s. An old college strain, the original breeder of Sour Diesel is unknown (although a lot of the cannabis neighborhood credits AJ— quick for “Asshole Joe”—for its creation). Its genetics are also unknown, but it is extensively believed that Sour Diesel is influenced by Chemdog 91 and Super Skunk.

Obtain Sour Diesel Nearby

Most shoppers associate Sour Diesel with gas aromas and an uplifting, energetic higher. But have you ever noticed inconsistencies in its aroma, flavor, and effects? Like a bored Bill Murray, Sour Diesel’s qualities can be all more than the location. Why?

For the reason that not all growers are developing the identical Sour Diesel. Aggregated lab information shows that strains labeled “Sour Diesel” are not constantly the identical, chemically speaking.

This could be due to:

  • Blatant dishonesty. There are no legal regulations about naming and labeling strains.
  • Lack of awareness. The growers assume they have Sour Diesel, but have an additional strain with a distinctive profile that they are calling “Sour Diesel.”

With its murky origins and genetics, there’s no uncomplicated way to authenticate which version is the “real” Sour Diesel. All we know for confident is that are various “Sour Diesel” chemotypes discovered in lab information sourced on the West Coast.

Working with aggregated information, Leafly’s lab partners observed 3 distinct chemotypes connected with the label “Sour Diesel.” Interestingly, just about all tested samples fell into a single of these 3 illustrated terpene buckets. Click to enlarge. (Elysse Feigenblatt/Leafly)

A chemotype refers to the chemical expression of a cannabis plant. Integrated in a plant’s chemotype are cannabinoids like THCA, THC, CBDA, and CBD. The other portion of a plant’s chemotype is the terpene profile, which refers to the aromatic compounds that make a plant’s fragrance and flavors and potentially influence its effects. With various Sour Diesel chemotypes and their varying terpene profiles, you may perhaps discover that not every single “Sour Diesel” impacts you the identical way.

We will refer to these distinctive chemotypes as “Sour Diesel A,” “Sour Diesel B,” and “Sour Diesel C.”

Sour Diesel A: Limonene-Dominant

The 1st chemical expression regularly discovered in lab data—what we’ll contact “Sour Diesel A”—is limonene-dominant, followed closely by an abundance of caryophyllene and myrcene. Although these are the 3 most prominent terpenes, this chemotype is also influenced by linalool and pinene.

It is significant to don’t forget the effects of cannabis are a mixture of these terpenes acting as a single, not just a auto complete of terpenes with limonene in the driver seat.

Sour Diesel B: Terpinolene-Dominant

“Sour Diesel B” is terpinolene-dominant, with secondary and tertiary terpenes of myrcene and pinene. Like Sour Diesel A, Sour Diesel B is a cornucopia of distinctive terpenes such as caryophyllene, humulene, linalool, and ocimene. With a terpene profile that appears practically nothing like Sour Diesel A’s, you may anticipate to discover a distinctive set of effects and aromas totally.

Sour Diesel C: Myrcene-Dominant

“Sour Diesel C” has a terpene profile that is extremely focused on myrcene production, followed by a touch of pinene. In smaller sized amounts, you will discover caryophyllene, humulene, linalool, and the uncommon ocimene.

The most significant takeaway from this debacle is that strain names are not as genuine as the chemical information behind them. Seeing “Sour Diesel” written on a label is not a surefire indicator of the effects or flavors to come, beyond the influence of the placebo impact. But figuring out which arrangement of cannabinoids and terpenes meet your demands can enable you discover the chemotype that hits the sweet spot.

This all highlights a bigger concern in cannabis, which is genetic authentication. With so several new named hybrids sprouting every single day, chemical information plays an increasingly significant part in figuring out what any provided strain has in shop for you. Although some strains exhibit additional chemical consistency than other folks, Sour Diesel is a prime instance of how lab-verified information can enable determine problematic inconsistencies attached to preferred strain names.
