MÜV Flower Review: Sour Jack (Sativa)

Note: All ratings for this strain were updated on 08.24.2020 to better reflect my experience after trying a higher-tier batch (T1) of this strain.

Sour Jack is the offspring of two of my favorite classic sativa strains: Sour Diesel and Jack Herer. I love both of these strains for different reasons: Sour Diesel is like the espresso of cannabis, with nearly unmatched energizing effects. On the contrast, Jack Herer is known for its ability to induce focus, making it a good strain for ADD, ADHD, and other similar mental focus-related ailments.

I’ve seen patients rave about Sour Jack for well over a year now, adding to my curiosity about how these two sativas would be when combined. After what seemed like months of not getting this strain at my local dispensary, I finally managed to grab an eighth of the T3 (small buds).

So, how does Sour Jack stack up to its superstar parents?

Quick Facts:

Sour Jack (Sativa) 

Price at time of review: $32/eighth (T3)

Lineage: Sour Diesel x Jack Herer

Batch/Harvest Number: BU220620-6570SJ

Cannabinoids

THC: 15.55%

CBD: 0.05%

Total Cannabinoids: 15.60%

Terpenes

Unfortunately, MÜV doesn’t make their lab reports available, so I have no terpene percentages to provide for this strain. Whenever this information becomes available, I will update this section with the terpenes and their percentages.

Appearance/Cure

Glass jar is my own; it is a recycled VidaCann flower jar.

MÜV’s T3 flower is $32 per eighth vs. the $50 pricetag of their T1 flower, and the $40 for T2. Per their website:

Tier 1 ($50) and Tier 2 ($40) are selected based on potency, size, structure, terpene profiles and aroma. Tier 3 is based on size only.

This eighth of Sour Jack was fully comprised of small, “rat pellet” size buds. Not exactly the most appealing thing to see when opening the pack, but hey – I bought the lowest tier, right?

The buds were on the dry side, but still seemed to have plenty of crystals. The physical appearance of Sour Jack, from what I can tell, leans to that of its Sour Diesel parent. I always recognized Jack Herer for both its extremely light green color, and its abundant coverage of vibrant orange pistils. Sour Diesel, on the other hand, has that forest green color with a shade darker orange pistils. As you can see in the images above, Sour Jack fits the latter description more.

After seeing other MMTCs up their flower game in the past few months, MÜV seems to be retaining the same quality that it has had since I started shopping there – which is still good quality, but it would be nice to see them improve at the same rate as the market. Maybe I’m just not getting the right strains?

Update 08.24.2020: I tried this strain again in T1 form. The cure was much better; though the buds were still small, the trichomes were easily visible and appeared to be more mature than the last batch. The trim and everything else seemed to be improved as well. With that in consideration, I will increase the score in this area from 6.00 to 7.20.

Appearance/Cure Rating: 7.20/10.00

Smell/Taste

Since both Sour Diesel and Jack Herer are pungent strains (albeit on different ends of the spectrum), I expected Sour Jack to possess an equally strong aroma, especially as some Reddit reviews indicated as much. Unfortunately, my eighth of Sour Jack did not have any sort of pungent aroma, but instead had a subtle scent that I had to focus on to find and describe.

Sour Diesel, in my experience, can vary from extremely pungent gas/diesel to a sort of loud citrus smell. I’ve tried it from both Trulieve (review here) and Fluent (review here); Trulieve’s Sour Diesel cut leans citrus (but still has notable diesel when ground up), and Fluent’s is heavily on the gas/diesel side.

Jack Herer, on the other hand, has always had a very sharp and pungent piney citrus aroma with a terpinolene-dominant terpene profile. Again, I’ve tried it from Trulieve (review here) and Fluent (review here); the smell was almost identical on both cuts.

So now that I’ve laid out the full spectrum of my experience with the smell and taste of the parent strains, where in that spectrum does Sour Jack fall?

Like with its physical appearance, I found Sour Jack to lean more toward its Sour Diesel parent in its smell – but fully on the citrus end of the spectrum; the gas/diesel terpenes were nowhere to be found in this eighth. The smell of Sour Jack when I ground it up, was actually sort of sweet, with citrus being the dominant smell, and an underlying earthiness in the background. I did not detect any terpinolene with my nose, but without a lab report, I can’t say if it is present or not. I can say that not much of the Jack Herer is present in the smell, unless some of the subtle citrus notes come from that parent.

The taste was much like the smell – smooth, subtle, and sweet citrus. Frankly, I expected to be more impressed by Sour Jack in this category, but maybe I got a weaker batch. I suppose I’ll revisit the strain if it’s available in T1 in the future; I don’t want to give up on a strain that has such good genetic potential just yet.

Update 08.24.2020: After trying this strain in T1, I am much more impressed with the smell and taste of this strain. The pungent diesel aroma from the Sour Diesel parent was much more prominent when the flower was pulled apart or ground up, though this wasn’t immediately noticeable with the flower in the jar. The earthy terpenes of Sour Diesel are what is most noticeable without handling the flower. The spicy, woody, piney terpenes of Jack Herer were faintly detectable when the flower was ground up, but overall, Sour Diesel seems to dominate this strain in the appearance and smell/taste. Considering this, I will increase the smell/taste score from 6.20 to 7.50.

Smell/Taste Rating: 7.50/10.00

Effects/Medical Use

Sour Jack leaned toward its Sour Diesel parent in the preceding categories, but it manages to find itself more balanced in the effects.

As I said before, I consider Sour Diesel to be my “cannabis espresso” and Jack Herer to be my “cannabis Adderall”. Sour Jack is not a speedy or racy strain, but it is not focused either. I find it to be right between Sour Diesel and Jack Herer – more mellow and uplifting, good for the mood – not necessarily a strain for motivation, energy, or focus.

Though there is some of a “sativa” energy boost associated with this strain, it isn’t overwhelmingly present. I smoked my last bowl just before i started typing this review; it is late morning, and I would best describe my mood as content. I am not really “in the zone” like I like to be after medicating with a sativa strain, but I am not aloof or unfocused either. Sour Jack seems to be right in the middle of the sativa effects spectrum, representing a good blend of the more subtle effects from its two parent strains.

With all that being said, I’d recommend to think of Sour Jack as its own unique strain if you’re buying it for its effects. If you want energy, stick with the Diesel. If you want focus and motivation, stick with Jack Herer. If you want a relatively mellow sativa to ease through the day on a fluffy cloud of happiness, but with a very light dose of energy, get Sour Jack.

Update 08.24.2020: Effects were consistent between the T3 and T1 batches, although they were possibly a bit more racy in the T1, which I believe was a more true representation of Sour Jack. The effects score will remain the same at 8.00.

Possibly good for treating:

  • Depression and associated anxiety
  • Lack of appetite
  • Minor headaches
  • Relief of minor skeletal/muscular aches and pains
  • Good for general relaxation (in higher doses or later in the day)

I’m definitely no medical doctor, so please take the preceding conditions only as my own personal observations from using this strain and having experience with a multitude of different cannabis strains. Everybody is different, and every body reacts differently to various medications. 

Effects Rating: 8.00/10.00

Overall Rating: 7.56/10.00

Overall, I would best describe Sour Jack as a “very good” sativa strain from MÜV.

While I wasn’t floored with this strain as I expected it to be, it was good enough that I want to give it another chance. I will get a higher tier next time, as I feel that the negatives in my experience can all be attributed to buying the Tier 3 small buds. A strain like this needs to be experienced at its full potential. If I do try T1 and have a notably better experience, that will birth an entirely new section for this site – “Round 2 Reviews”. We will cross that bridge if and when we get to it!

  1. Try their cherry punch flower! Amazing hybrid! I buy T1 or T3 as they have the same potency! Great taste, not harsh and a great euphoric high that lasts!

  2. Definitely try the higher tier; I think you’ll find what you were looking for with this lineage. At least, that was my experience.
