Every dynasty has its heir apparent and its dark horse. In the Runtz family, that dark horse is Black Runtz.
If you followed the cannabis world in 2020, you watched Runtz become a phenomenon. Leafly crowned it Strain of the Year. Over 100 rap songs name-dropped it. Cookies couldn’t keep it on shelves. The original Runtz was everywhere, all bright colors and candy vibes, the golden child that could do no wrong.
But while everyone was chasing the spotlight, something darker was brewing in British Columbia. Big Boss Farms was quietly developing what Leafly would later call “the dark twin” of the 2020 Strain of the Year. Same legendary parents. Deeper colors. Heavier effects. This is Black Runtz, and it’s not interested in being second best.
The Bloodline: Cannabis Royalty
Black Runtz didn’t earn its reputation by accident. Look at the lineage and you’ll understand why connoisseurs take it seriously.
The parent strains read like a cannabis hall of fame. Zkittlez took the Cannabis Cup Michigan in 2015 and dominated the Emerald Cup California in 2016. Gelato was Leafly’s 2018 Strain of the Year. Their offspring, Runtz, claimed the 2020 crown. That’s three consecutive years of industry-defining genetics feeding directly into Black Runtz.Where Black Runtz diverges from its famous sibling is in expression. This phenotype leans indica-dominant at roughly 55/45, which means it inherited more of the body-heavy, relaxation-forward traits from its Zkittlez side. The result is a strain that hits different, quite literally, than the balanced hybrid experience of standard Runtz.

Bag Appeal: The Dark Side Looks Good
One look at Black Runtz and you understand the name. These aren’t the bright, candy-colored nugs you’d expect from a Runtz variant. Black Runtz buds run deep olive green shot through with dark purple hues that can border on black in certain lighting. Pink-tinted sugar leaves wind through the upper portions, creating contrast against that moody backdrop.
The trichome coverage is serious. A thick frost of white crystal trichomes blankets every surface, making the buds sticky to the touch and glistening under light like they’ve been dusted with powdered sugar. Dense and oversized, these spade-shaped nugs have the kind of bag appeal that makes you pause before breaking them up.

The Nose Knows: Cracking the Jar
Open a jar of quality Black Runtz and the first thing you notice is that signature Runtz sweetness, but with depth. There’s a creamy, citrus-forward aroma that hits immediately, like opening a bag of your favorite sour candy. But underneath that brightness, you’ll catch diesel notes and something earthier, spicier. It’s layered in a way that keeps revealing new dimensions.
The flavor follows suit. On the inhale, it’s all sweet berry and tropical fruit with citrus brightness. The exhale is where it gets interesting, bringing through subtle spice and fresh earthiness that balances the sweetness. Some users describe hints of flowery roses and fresh herbs lingering on the palate. The smoke itself is creamy and smooth, which makes sense given the Gelato influence in its genetics.
Terpene Profile: The Chemistry Behind the Experience
Black Runtz is limonene-dominant, which explains that bright citrus character in both aroma and effect. Limonene is associated with mood elevation, contributing to the uplifting onset that Black Runtz is known for.
Myrcene comes in strong as a supporting player, adding those earthy, herbal undertones and contributing to the strain’s sedative qualities. This is the terpene responsible for that body-heavy relaxation that settles in after the initial cerebral lift.
Caryophyllene rounds out the profile with peppery, spicy notes. Beyond flavor, caryophyllene is the only terpene known to interact directly with the endocannabinoid system.
Together, these three create what terpene enthusiasts call a complex profile: one that delivers a multi-dimensional experience rather than a one-note high.

The Experience: What the Dark Side Feels Like
Black Runtz is a creeper. That’s important to understand before you dive in.
The high doesn’t announce itself immediately. It hangs out in the background for a few minutes, then gradually takes center stage. First comes the cerebral lift, a wave of euphoria and mental brightness that sharpens mood and sparks conversation. Users consistently report feeling more social, more talkative, more engaged with whatever’s in front of them.
Then the body high arrives. Not all at once, but like a warm blanket settling over you. Physical tension dissolves. Muscles you didn’t realize you were clenching start to relax. The couch starts looking very, very comfortable.
With THC levels typically ranging from 24% to 30%, Black Runtz is not a starter strain. This is flower for experienced consumers who understand their tolerance and respect potency. The effects are long-lasting and progressively sedating, making it ideal for evening use when you don’t have anywhere to be.
Leafly user reviews frequently mention three effects: relaxed, happy, and aroused. That combination, the mood elevation paired with deep physical relaxation, explains why Black Runtz has developed such a loyal following among those who prioritize evening unwinding.
Who Should Give in to the Dark Side
Black Runtz isn’t trying to be everything to everyone, and that’s part of its appeal.
If you’re looking for a daytime productivity strain, keep looking. Black Runtz is built for the hours after work, for winding down, for letting go of the day’s tension. It’s the strain you reach for when the goal is relaxation, not accomplishment.
Users who have trouble winding down at night often gravitate toward Black Runtz. The combination of mood elevation and body relaxation makes it a go-to for those looking to quiet a busy mind before sleep.
Runtz family loyalists will find Black Runtz to be a worthy evolution. If you’ve loved White Runtz or Pink Runtz but wanted something with more weight to it, something that leans heavier into relaxation, Black Runtz is likely your next favorite.
The Dark Twin: Standing Out in a Crowded Market
Leafly calls Black Runtz “the dark twin” of their 2020 Strain of the Year, and that positioning tells you everything you need to know. This isn’t a knockoff riding the Runtz name. It’s a legitimate phenotype that earned its reputation by being darker, deeper, and more indica-forward than its famous sibling.
The lineage speaks for itself. Gelato took the High Times Cannabis Cup for Best Hybrid in 2018. Zkittlez won Cannabis Cup Michigan in 2015 for Best Indica and dominated the Emerald Cup California in 2016. When your parent strains are stacking trophies like that, the genetics aren’t in question.
In a market flooded with Runtz variants, some legitimate and many not, Black Runtz stands out for being exactly what it claims to be. Where standard Runtz is bright and balanced, Black Runtz is moody and relaxation-forward. Where Runtz works any time of day, Black Runtz owns the evening.
For the THCA flower consumer who wants strain-of-the-year genetics with a twist, who appreciates visual drama alongside serious effects, who knows their tolerance and wants something that delivers, Black Runtz is worth the hype.
Sometimes the dark side is exactly where you want to be.
Is Black Runtz Worth the Price? (And Why Emerald Smoke Changes Everything)
Here’s where things get interesting. At most dispensaries and online shops, you’ll see Black Runtz priced at $150-200 per ounce, sometimes more for supposedly “authentic” cuts. That premium pricing reflects the Runtz lineage hype, the cultivation difficulty, and genuine market demand for quality genetics.
But here’s the thing: at Emerald Smoke, we’re talking $99/oz for premium Black Runtz. And if you grab the 4oz bundle for $297, you’re looking at $74.25 per ounce.
Let that sink in. You’re getting the same complex terpene profile, the same balanced effects, the same bag appeal, for less than half what most places charge. We’re not cutting corners on quality; we’re just not marking it up 300% because we can.
So is Black Runtz worth it? At $74-99/oz? Absolutely. You’re paying less than budget flower costs at most dispensaries, but getting connoisseur-grade genetics with full lab testing. At $180/oz from other vendors? Maybe, if you’re really chasing that specific experience. But why pay double when you can get verified Black Runtz at wholesale pricing?
Think of it like this: we’re giving you craft beer at Bud Light prices. The quality is there, the genetics are authentic, the testing backs it up. We’re just not gouging you for it.
