Written by Ad OpsOrigins and Breeding History
Merlot OG is a mostly indica cultivar developed by the California-based breeder and extraction house Moxie 710. Known for pairing high-resin flower with competition-grade concentrates, Moxie 710 built its reputation in the 2010s across medical and adult-use markets. Merlot OG fits squarely within that pedigree: a resin-forward selection meant to deliver dense trichome coverage and a terpene profile that stands up both in flower and in extracts.
The strain name signals a wine-inspired sensory experience, hinting at dark fruit and tannic, earthy undertones. While the cannabis community often associates the word OG with classic OG Kush families, Merlot OG also telegraphs a richer, jammy bouquet than a straight diesel-pine pheno. This positioning reflects Moxie 710’s emphasis on aroma-driven breeding, a hallmark of Northern and Southern California craft programs.
In the broader market, Merlot OG has circulated primarily as flower drops and limited-run concentrates rather than mass-distributed seeds. That distribution strategy is consistent with Moxie 710’s concentrate-first brand identity and closed-loop extraction expertise. As a result, Merlot OG quickly became a connoisseur pick where available, with batches valued for their terpene intensity and sedative indica expression.
Because batches were often paired to extraction schedules, Merlot OG’s harvest timing tends to aim at peak resin maturity. This mirrors practices highlighted in buyer’s guides to Northern California concentrates, which emphasize harvesting at the optimal moment for closed-loop BHO extraction to maximize cannabinoids and terpenes. In short, Merlot OG was bred and managed like a solventless- and hydrocarbon-friendly resin producer built to shine under the microscope and on the palate.
Genetic Lineage and Taxonomy
Merlot OG’s precise parentage has not been publicly and definitively disclosed by Moxie 710. In the cannabis world, especially with proprietary breeding programs, it is common to keep certain crosses private to protect unique IP. This lack of full public documentation aligns with large genealogy databases that include branches marked as Unknown, reflecting how many modern cultivars are derived from partially undisclosed lines.
Taxonomically, Merlot OG presents as an indica-leaning hybrid, with most growers and consumers describing it around a 70/30 to 80/20 indica-to-sativa expression. That categorization is based on plant morphology, flowering time, and experiential effects rather than a pure landrace taxonomy. Its bud density, internodal spacing, and relaxing effect profile all point toward heavy indica influence with some hybrid vigor.
Phenotypically, Merlot OG shares several markers common to OG-derived families: medium-height bushes, broadleaf-dominant leaves, and firm, resin-caked calyxes. The terpene profile—often rich in myrcene, limonene, and beta-caryophyllene—also reads OG-adjacent, while the flavor leans darker and fruitier than a classic lemon-pinechem OG. These clues suggest OG lineage somewhere in its family tree, even if the exact cross remains proprietary.
It is worth noting that multiple cuts or phenotypes can circulate under a single strain name as cultivators hunt for production or terpene differences. In practice, this means you may encounter slight variance in Merlot OG’s bouquet and potency between grows. Nevertheless, the core indica-forward structure and wine-kissed aroma theme are consistent anchors across authentic releases.
Visual Characteristics and Bud Structure
Merlot OG typically develops compact, conical colas with notable calyx stacking and minimal stem-to-bud ratio. The buds often present a deep forest-green base, overlaid with amber-orange pistils and a thick, silvery trichome sheath. Under cooler night temperatures, some phenotypes exhibit faint maroon or plum accents as anthocyanins express near bracts and sugar leaves.
The trichome coverage skews heavily toward capitate-stalked glandular heads—the large, resin-rich structures prized for extraction. Healthy, mature flowers show a dense carpet of cloudy to mostly milky heads at peak ripeness, with amber mottling as harvest nears. This resin density correlates with the strain’s reputation for robust concentrate yields.
Leaf morphology tends to be broad and short-lobed with a classic indica serration pattern. Internodes sit tighter than in lankier sativa-dominant hybrids, promoting a bushy profile that responds well to canopy management. When properly trained, the canopy forms an even mat that supports uniform light distribution and consistent bud development.
Trimmed buds are typically medium to large, with a high apparent density when pressed between fingers. The combination of tight calyx formation and low fluff content leads to a satisfying hand-feel and slower burn rate when cured correctly. Expect an attractive frost-forward bag appeal that looks purpose-built for both connoisseur flower jars and microscope shots.
Aroma and Bouquet
Merlot OG’s aroma leans into dark fruit and wine-barrel complexity layered over classic OG earth and fuel. The top notes evoke black cherry, red grape skins, and a hint of plum reduction, giving the bouquet a jammy first impression. Beneath that, a structured base of damp soil, pine resin, and peppery spice creates a grounded backbone.
As the flower is broken down, the profile opens into citrus rind brightness—often a limonene lift—followed by diesel-adjacent hydrocarbons typical of OG families. A trace of floral sweetness, likely from linalool and related monoterpenes, rounds off the nose. The net effect is a full-spectrum aroma that swings from fruit-forward to gassy and back again.
Freshly cured samples often test higher in terpene intensity, a factor that can diminish with mishandled storage or extended shelf time. Best-in-class batches maintain 2.0–3.0% total terpene content by weight, which translates into a room-filling nose upon opening the jar. Sensitive noses may also pick up a faint cocoa or tannic oak note, reinforcing the wine-inspired namesake.
In concentrates, the bouquet tilts more deeply into grape-jam meets pine and pepper, with the gas element sharpening in hydrocarbon extracts. Closed-loop BHO often captures the diesel and spice dimensions while preserving the fruit, reflecting harvests tuned for peak resin as practiced by leading NorCal concentrate producers. The result is a terpene-forward experience that mirrors top-shelf flower while amplifying complexity.
Flavor Profile and Combustion Notes
On the inhale, Merlot OG delivers a layered flavor of dark berries, grape must, and sweet earth. A faint citrus-zest edge brightens the palate, preventing the profile from becoming cloying. The exhale pivots to OG territory: pine, pepper, and a wisp of fuel.
When vaporized at lower temperatures (175–190 C), the fruit and floral components are most prominent. Increasing heat into the 195–205 C range brings forward the caryophyllene-driven spice and a deeper earthy resonance. Combustion in glass or clean rolling papers tends to emphasize the pine-diesel base while retaining enough fruit to justify the name.
The mouthfeel is medium-bodied with a slightly resinous, lingering finish that recalls wine tannins without bitterness. Properly cured buds burn to a light-gray ash, indicating good mineral balance and slow, even drying. A well-managed cure enhances sweetness and rounds off any harshness from residual chlorophyll.
In extracts and live resins, expect a saturated, syrupy fruit core riding atop crisp OG spice. The flavor persists over multiple pulls, especially in cold-cured preparations that preserve delicate monoterpenes. For flavor-chasers, Merlot OG rewards careful temperature control and glass cleanliness to avoid muddling its layered profile.
Cannabinoid Chemistry and Potency
Merlot OG is typically high-THC with low CBD, consistent with modern indica-dominant hybrids. In legal U.S. markets, indica-leaning cultivars commonly range between 18–26% THC by weight, with top-shelf craft batches occasionally pushing higher. Merlot OG often falls toward the upper half of that range when cultivated under optimized lighting and nutrition.
CBD is generally present in trace amounts, commonly below 1.0% by weight. Minor cannabinoids such as CBG may appear in the 0.2–1.0% range, depending on harvest maturity and cultivar expression. Total cannabinoids in well-grown flower can reasonably land between 20–30% by weight, with concentrates vastly exceeding that.
Potency is not solely a function of genetics; growing conditions and post-harvest practices materially impact the final numbers. Even a small shift in harvest timing—pulling with predominantly cloudy trichomes vs. waiting for 15–20% amber—can alter the perceived effect and lab outcomes. Likewise, light intensity, environmental stability, and cure discipline affect both measured potency and subjective strength.
For concentrates produced via closed-loop BHO, total THC often surpasses 70% by weight, with terpene content frequently in the 5–15% range depending on extraction style. Producers aligned with Northern California best practices prioritize harvesting at the optimal moment specifically to maximize these metrics. Those choices are consistent with Merlot OG’s resin-driven breeding and its pairing with high-end extracts.
Terpene Profile and Minor Volatiles
While exact terpene readings vary by batch, Merlot OG commonly expresses a myrcene-limonene-beta-caryophyllene triad. In many OG-leaning cultivars, typical individual terpene ranges look like myrcene at 0.3–0.9%, limonene at 0.4–0.8%, and beta-caryophyllene at 0.2–0.5% by weight. Alpha-pinene (0.1–0.3%) and linalool (0.05–0.20%) often round out the dominant set.
Total terpene content in well-grown Merlot OG flower frequently lands between 1.5–3.0%, a range associated with robust aroma and flavor persistence. Higher terpene totals correlate with stronger perceived effects for many consumers, plausibly via entourage interactions. Notably, beta-caryophyllene is a dietary cannabinoid capable of binding CB2 receptors, potentially modulating inflammation pathways.
Myrcene often supports the heavy, couchlock-adjacent body feel, while limonene contributes to mood elevation and a sense of uplift. Pinene can add cognitive clarity in earlier stages of the session, and linalool may provide a calming floral undercurrent. Together, these compounds frame Merlot OG’s signature wine-meets-OG sensory arc.
Minor volatiles such as ocimene, nerolidol, and humulene may appear in trace amounts that nonetheless influence the bouquet. These can add green, herbal top notes or deepen the woody base. In concentrate form, monoterpenes tend to volatilize quickly, so cold-cure and fresh-frozen processes help retain the nuanced top-end.
Experiential Effects and Use Cases
Subjectively, Merlot OG begins with a warm, euphoric onset that many describe as a mood-softening lift. Within minutes, the body relaxation builds, often settling into the shoulders, lower back, and jaw. The headspace calms without necessarily collapsing into heaviness right away.
As the session progresses, the indica character becomes more pronounced. Users commonly report tension relief and a gentle deceleration of racing thoughts, followed by an enjoyable body weight. At moderate doses, expect a sociable, mellow calm; at higher doses, a couch-friendly stillness often takes over.
Merlot OG’s arc makes it well-suited for evening use, movie nights, or post-work decompression. Creative tasks that benefit from relaxation rather than high-speed ideation can pair nicely with the strain’s cushiony focus. Many consumers find that it transitions smoothly into sleep when consumed closer to bedtime.
Duration varies by route and dose, but inhaled effects typically sustain for 2–4 hours, with a longer tail in sensitive individuals. Edible or sublingual formats made from Merlot OG extracts may extend relief to 4–6 hours or more. As always, titrate low to start and increase gradually to find the ideal personal window.
Potential Therapeutic Applications
Consumers often reach for Merlot OG for stress modulation, physical relaxation, and sleep support. The combination of THC with myrcene and linalool is frequently associated with calming, anxiolytic-leaning experiences for some users. Beta-caryophyllene’s engagement with CB2 may complement these effects by modulating peripheral inflammation signaling.
Anecdotal reports suggest utility for muscle tension, menstrual discomfort, and post-exercise soreness. In broader observational data, cannabis use has been associated with reductions in self-reported pain scores and improved sleep quality. For example, app-based symptom tracking studies have documented clinically meaningful reductions across pain and insomnia measures after cannabis use, though individual responses vary and controlled trials are needed for definitive conclusions.
Importantly, cannabis affects people differently based on dose, tolerance, and context. High-THC, indica-leaning strains like Merlot OG can be sedating or overwhelming for inexperienced users, particularly at larger doses. Patients should consult healthcare professionals, start low, and observe interactions with other medications or conditions.

Comprehensive Cultivation Guide
Legal note: Cultivation laws vary widely; always comply with local regulations regarding plant counts, licensing, and security. The following information is horticultural guidance intended for compliant cultivation settings. A focus on environment, nutrition, and harvest timing is key to realizing Merlot OG’s resin potential.
Growth habit and training: Merlot OG grows as a medium-height, broadleaf-dominant hybrid with tight internodal spacing. Topping at the 4th–6th node followed by low-stress training (LST) or a SCROG net helps create an even canopy. Because of dense bud formation, early defoliation (selective, not aggressive) improves airflow and light penetration.
Environment: Ideal daytime temperatures run 24–27 C (75–80 F) with nighttime drops to 18–21 C (65–70 F). Relative humidity targets start higher in veg (55–65% RH) and taper to 40–50% in mid-to-late flower to reduce botrytis risk. Vapor pressure deficit (VPD) in the range of 0.9–1.2 kPa in veg and 1.2–1.5 kPa in flower supports vigorous transpiration and resin production.
Lighting: In veg, aim for 400–600 PPFD with a daily light integral (DLI) of 25–35 mol/m2/day. In flower, 900–1,200 PPFD is a productive range for non-CO2 rooms, with careful acclimation to avoid light stress. If supplementing CO2 (800–1,200 ppm), the cultivar can often utilize the upper end of that PPFD range for increased yield potential.
Medium and nutrition: Merlot OG performs well in inert media (coco/perlite) and quality soilless mixes with robust aeration. Maintain pH around 5.8–6.2 in hydro/coco and 6.2–6.6 in soil. Electrical conductivity (EC) can progress from 1.2–1.6 in veg to 1.8–2.2 in peak flower, with a slight taper before flush.
Feeding strategy: This cultivar appreciates a steady supply of calcium and magnesium, particularly under high-intensity LEDs. Early flower requires a balanced NPK with phosphorus and potassium ramping from week 3 onward. Silica supplementation can strengthen stems to support dense colas.
Irrigation: In coco, water to 10–20% runoff once or twice daily, adjusting frequency to root mass and container size. In soil, allow a moderate dryback to encourage oxygenation while avoiding hydrophobic cycles. Consistency reduces stress and stabilizes uptake, improving terpene retention.
Flowering time and yield: Expect an 8–9 week flowering window (56–63 days) for most phenotypes under 12/12 photoperiod. Indoor yields in a dialed environment can reach 450–600 g/m2 with proper training and environmental control. Outdoor or greenhouse plants, where legal, can be harvested in late September to early October in temperate climates.
Pest and disease management: Dense, resinous buds necessitate proactive airflow and humidity management to prevent powdery mildew and botrytis. Implement integrated pest management (IPM) with routine scouting, sticky cards, and biological controls such as predatory mites where appropriate. Maintain clean intakes, sanitize tools, and avoid overcrowding.
Phenotype selection: If hunting multiple seeds or cuts, prioritize phenotypes that stack calyxes without excessive leafiness and that express the fruit-forward OG aroma. Keep meticulous notes on stretch, internode spacing, and resin onset (often visible by week 3–4). Selecting for high terpene output improves both flower desirability and extraction performance.
Pre-harvest practices: Reduce nitrogen in the final 10–14 days and consider a light flush to enhance clean burn and color. Gradually lower nighttime temperatures to the high teens Celsius to coax anthocyanin expression without stressing the plant. Monitor trichomes with a jeweler’s loupe or microscope to time harvest precisely.
Post-Harvest Handling, Curing, and Extraction
Drying: Target a slow, controlled dry at approximately 60 F (15.5 C) and 55–60% RH for 10–14 days. This tempo preserves monoterpenes while preventing mold in dense colas. Gentle air movement that does not directly hit flowers is ideal.
Curing: Once stems snap with slight bend, transfer to airtight containers at 62% RH, burping daily for the first 7–10 days. Thereafter, burp weekly as aromas mature, aiming for a 2–8 week cure depending on preference. Proper curing can enhance perceived sweetness and smoothness while stabilizing the wine-like aromatics.
Harvest timing: For a heavier, more sedative profile, many growers harvest when 15–20% of trichome heads turn amber with the rest cloudy. For a brighter, more balanced effect, harvest closer to full-cloudy with minimal amber. Differences in timing can subtly shift both cannabinoid ratios and terpene expression.
Extraction: Merlot OG is well-suited to closed-loop BHO extraction thanks to its capitate-stalked trichome abundance and robust terpene set. Northern California concentrate producers, as highlighted in buyer guides, optimize harvest to peak cannabinoid and terpene content for precisely this style. Fresh-frozen material can produce live resins with a saturated fruit-pine profile, while cured resins emphasize OG spice and fuel.
Post-processing: Cold-cure techniques can preserve top notes, whereas gentle heat-assisted whipping may produce a batter-like consistency that balances fruit and gas. For rosin, low-temp presses of 180–200 F can yield flavorful, stable extracts if starting material is high grade. In all cases, solvent handling and extraction must be performed with compliant, closed-loop systems and appropriate licensing.
Market Context, Availability, and Buyer Tips
Merlot OG has generally circulated in limited releases, aligning with Moxie 710’s focus on curated drops tied to concentrate programs. Availability can be seasonal and region-dependent, with California seeing the most consistent access. Because the name carries strong brand association, look for verified provenance through dispensary networks that source directly from licensed producers.
When shopping, prioritize freshness and terpene transparency. Flower packaged within the last 60–90 days tends to retain brighter aromatics, while lab results listing total terpenes (ideally 2.0% or higher) can be a reliable quality proxy. Potency numbers matter, but in consumer surveys, terpene content often correlates more closely with enjoyment and perceived effect character.
Visually inspect buds for dense calyx stacking, intact trichome heads, and clean trim with minimal stem. On the nose, seek the signature fruit-meets-OG duality: grape-cherry tones balanced by pine, pepper, and a hint of fuel. For concentrates, look for clarity, homogeneity, and an aromatic profile that mirrors top-quality flower rather than a generic gassy smear.
Pricing varies by market, but craft indoor eighths often command a premium over commodity flower. Depending on region, expect a range that reflects small-batch production and high terpene content. Ultimately, the value proposition rests on Merlot OG’s distinct sensory experience and reliable indica-forward effects.
Evidence, Data Notes, and Context Integration
Public, batch-specific lab datasets for proprietary cultivars like Merlot OG are limited, especially when seed distribution is restricted and cuts circulate mainly through licensed producers. Where direct numbers are unavailable, reasonable ranges are provided based on common lab outcomes for indica-leaning OG-family flowers in regulated U.S. markets. These typically include THC in the upper teens to mid-20s percentage by weight, total terpenes around 1.5–3.0%, and minor cannabinoids such as CBG under 1%.
Genealogical opacity is common in modern cannabis breeding, and large databases document branches labeled as Unknown. This reflects the prevalence of proprietary and unrecorded crosses in strain family trees and supports cautious lineage discussion when primary sources are not public. In this context, describing Merlot OG as a mostly indica hybrid bred by Moxie 710 is supported, while asserting exact parents would overstep the evidence.
Finally, best practices discussed for capturing peak resin and terpenes in concentrates align with Northern California’s closed-loop BHO standards. Buyer guides to the region’s concentrate scene emphasize optimizing for cannabinoid and terpene production and harvesting at the optimal moment for closed-loop extraction. Those practices dovetail with Moxie 710’s reputation and the resin-forward design of Merlot OG, linking breeding intent to market execution.
As with all cultivation and consumption guidance, local legal compliance is paramount. Product quality varies by producer and batch, so rely on updated certificates of analysis and trusted retailers. Use the provided ranges and recommendations as a foundation, then refine based on real-world results and personal goals.
