Kosher Kush, popularly known in legacy circles as Jew Gold, is a heavyweight indica-leaning cultivar that rose from Los Angeles OG lineage to global fame. Its reputation rests on soaring potency, resin-drenched flowers, and an unmistakable gassy-citrus aroma that OG lovers instantly recognize.
In dispensary data sets and public lab reports, Kosher Kush frequently posts THC above 20%, with many batches clocking 22–26% and select cuts reaching 28–29%. CBD remains minimal, typically under 1%, underscoring a decidedly psychoactive chemotype built for depth and sedation.
The strain’s notoriety was cemented by multiple High Times Cannabis Cup wins in the early 2010s, where it consistently dominated Best Indica categories. Those victories reflected what connoisseurs already knew: among OG-derived varieties, this one punches hardest and finishes smooth.
Growers prize Kosher Kush for its dense, boulder-like colas and thick trichome mats that make trimming sticky work but boost bag appeal. Well-grown flowers showcase jade-to-forest-green hues with flaming orange stigmas, often dusted white under millimeter-thick resin frost.
Whether you call it Kosher Kush or Jew Gold, the target strain carries a rare combination of brute force, refined flavor, and reliable effects. It is simultaneously a flagship for OG purists and a benchmark indica for patients seeking nighttime relief.
Origin Story and Cultural History
Kosher Kush traces its roots to the Los Angeles underground of the 2000s, where elite OG Kush cuts circulated among tight-knit grower communities. The moniker Jew Gold emerged from a storied clone passed among Jewish growers, prized for quality and guarded like currency.
As the cut’s popularity grew, breeders from the DNA Genetics/Reserva Privada camp stabilized and released it more broadly under the name Kosher Kush. The rebrand paired a cheeky nod to tradition with wider market sensibilities, helping the cultivar cross from legend to SKU.
Between 2010 and 2012, Kosher Kush racked up multiple High Times Cannabis Cup trophies, including Best Indica honors. Those podium finishes were not flukes; they reflected a pattern of judges praising its heavy-on-the-palette OG fuel and bone-deep relaxation.
A persistent legend holds that a rabbi once blessed a grow of Kosher Kush, giving rise to the “Kosher” tag. While anecdotal, the story underscores its cultural cachet and the reverent way the community regarded the cut.
As legalization spread, the strain traveled from California to Canada, Europe, and beyond, showing up in menus under both Kosher Kush and Jew Gold. Despite regional naming preferences, consumers consistently recognize it for potent nighttime sessions and classic OG flavor architecture.
By the late 2010s, Kosher Kush had become a breeding parent in several projects, spawning crosses that lean into lemon, gas, or purple hues. Even so, the original remains a go-to for purists who want the archetypal OG experience without dilution.
Genetic Lineage and Breeding Notes
Kosher Kush descends from the OG Kush family tree, likely selected from an LA OG population with unknown exact parents. The consensus is that it is an exceptional phenotype rather than a multi-parent polyhybrid, with stabilization done through selection and line work.
OG lineage brings hallmark traits: lemon-fuel top notes, earthy pine undertones, lanky early structure, and late-flower density. Kosher Kush amplifies these into thicker colas and above-average resin output that hashmakers notice.
Breeders have reported two recurring expressions when pheno-hunting: a lemon-forward, sharper-gas profile and a deeper earthy-gas with pepper and incense. Both test high for THC, but the lemon-forward typically finishes one to three days sooner and may carry slightly higher limonene.
In crosses, Kosher Kush tends to pass on its density, strong apical dominance, and OG terpene stack. Pairings with citrus-forward partners often yield big-limonene chemotypes, while crossings with purple-leaning lines can produce berry-gas hybrids with heavy sedative profiles.
Internodal spacing starts medium in vegetative growth but tightens quickly in weeks 3–5 of flower, concentrating weight. That compression, combined with a calyx-forward bud set, creates a respectable calyx-to-leaf ratio around 60:40 in dialed-in environments.
While true pedigree documentation is limited by the OG family’s murky origins, consistent chemotype outputs across markets suggest a relatively stable clone line. Seeded versions vary more, making selection critical for growers chasing the original cup-winning profile.
Botanical Appearance and Morphology
Kosher Kush expresses medium-tall stature with vigorous apical growth and strong lateral branches capable of carrying weight. In veg, leaves are broad, dark green, and lightly clawed at high nitrogen, signaling classic OG feeding sensitivities.
During stretch, expect 1.5–2.0x vertical expansion in the first 14–18 days of 12/12. Trellising or SCROG helps distribute colas and prevents toppling as flowers pack on mass from week 5 onward.
Mature buds are golf-ball to soda-can sized, with tight calyx stacking and minimal foxtailing when temperatures stay below 27°C in late flower. Resin output is conspicuous by week 4, often giving a frosted look that deepens as capitate-stalked trichomes proliferate.
Coloration ranges from lime to deep forest green with thick, burnt-orange pistils that darken as they oxidize. Anthocyanin expression is mild in most cuts, though night drops to 17–18°C in late bloom can coax faint purples in sugar leaves.
Under high-intensity LED (900–1100 µmol/m²/s PPFD), the cultivar builds dense core colas with minimal larf if defoliation and pruning are timed well. Left unmanaged, lower growth can shade out and reduce usable A-grade yield by 10–20%, a common OG trait.
Aroma and Bouquet
The bouquet is unabashedly OG: sour lemon peel, diesel fumes, pine sap, and damp earth. On the break, a peppery spice and faint incense emerge, suggesting caryophyllene and linalool co-acting beneath the limonene top notes.
Freshly ground flowers release a rush of volatile terpenes that spike in the first 30 seconds, so aroma assessment is best done immediately. Many users report a “nose-tingle” effect attributed to sharp monoterpenes that quickly oxidize in open air.
As buds cure, the lemon sharpness mellows into rounded citrus-oil with a sweeter edge, while the gas note deepens. A well-cured sample maintains its top-end brightness for 6–8 weeks if stored at 55–62% RH in sealed glass containers.
Compared to other OGs, Kosher Kush’s scent skews slightly heavier and earthier, with less pine-sol and more fuel-oak interplay. The result is a mature, layered aroma that signals potency before the first draw.
Hash and rosin made from Kosher Kush concentrate the gas and incense into a penetrating, room-filling scent. Solventless rosin often reads as lemon-zest over warm pepper, while hydrocarbon extracts skew towards high-octane fuel.
Flavor and Combustion Characteristics
The first pull delivers lemon-diesel on the tongue with a peppery exhale that tickles the soft palate. Secondary notes of pine needle and earthy hash linger, especially in slow, low-temperature vaporization.
Combustion is smooth when flowers are properly flushed and cured to 10–12% moisture content. Harshness increases if chlorophyll isn’t adequately broken down, revealing itself as throat scratch and a grassy aftertaste.
In concentrates, flavor condenses into bright citrus-fronted gas that persists through multiple low-temp dabs. Solventless preparations tend to emphasize zest and spice, while BHO live resins spotlight jet fuel and polished pine.
Repeat tasters often describe Kosher Kush as “true OG” in the mouth—dense, oily smoke with a lingering lemon-pepper signature. That coherence between nose and palate is a big part of its enduring fan base.
Cannabinoid Profile and Potency Stats
Kosher Kush is a high-THC, low-CBD cultivar by design, repeatedly testing in the low-to-high 20s for THC. Typical dispensary batches land between 20–26% THC, with outliers approaching 28–29% in dialed-in grows.
CBD generally registers below 1% and often below 0.3%, placing it squarely in Type I (THC-dominant) chemotype territory. Minor cannabinoids such as CBG and CBC appear in trace-to-low amounts, commonly 0.1–0.6% combined.
Total cannabinoids routinely measure 22–32%, depending on cure and lab methodology. Higher total cannabinoid readings correlate with well-developed trichome heads and careful post-harvest handling that prevents terp and cannabinoid volatilization.
For perspective, a 0.5 g joint of 22% THC flower contains roughly 110 mg of total THC potential before combustion loss. With average delivery efficiencies of 20–37% for smoked routes, a consumer might absorb 22–41 mg of THC from that half-gram.
Edibles prepared from Kosher Kush trim or rosin can be exceptionally potent due to low CBD counterbalance. Standard cautious dosing of 2.5–5 mg THC is appropriate for new users, while experienced consumers may target 10–20 mg per session.
While the chemotype is consistent, batch-to-batch variance exists based on phenotype, environment, and harvest timing. Trichome maturity and minimal oxidative loss during dry/cure are tangible levers that influence final potency metrics.
Terpene Profile and Volatile Chemistry
Kosher Kush’s terpene profile is dominated by β-myrcene, limonene, and β-caryophyllene, supported by linalool, humulene, and α/β-pinene. The result is a total terpene content commonly ranging from 1.5–3.0% of dried weight in optimized grows.
β-Myrcene often leads at 0.5–1.2%, imparting earthy, musky tones and synergizing with THC to deepen sedation. Limonene follows in the 0.3–0.8% band, contributing lemon-zest brightness and perceived mood lift.
β-Caryophyllene typically lands at 0.2–0.6%, adding peppery spice and engaging the CB2 receptor associated with anti-inflammatory effects. Linalool, usually 0.1–0.3%, rounds out the bouquet with floral-incense nuances that some users associate with calm.
Humulene is present around 0.1–0.2%, lending woody, herbaceous notes and a subtle dry finish. Pinene (0.05–0.15%) adds a pine-needle snap that is more detectable on retrohale than on the initial draw.
Terpinolene is generally minimal (<0.05%), distinguishing Kosher Kush from terpene profiles of Jack or some Haze lines where it dominates. That low terpinolene content aligns with its indica-leaning, sedative experiential profile rather than an energetic one.
Proper curing preserves monoterpenes that volatilize quickly above 20–22°C. Storing at 55–62% RH and 15–20°C can retain 10–25% more terpene content over six weeks compared to room temperatures above 24°C.
Experiential Effects and Use Patterns
Kosher Kush delivers a rapid-onset, heavy body effect for inhaled routes, with peak intensity arriving within 10–20 minutes. Users commonly report a head-to-toe melting sensation, loose limbs, and a calm mental hush that quiets ruminating thoughts.
The high is strongly felt for 60–120 minutes with inhalation, tapering over 2–4 hours depending on dose and tolerance. Edibles shift the curve to a 45–90 minute onset and 4–8 hour duration, often amplifying sedative qualities.
Euphoria is present but grounded, more contentment than giddy stimulation. Many consumers reserve the strain for evenings due to its couch-lock potential, though low doses can be workable for daytime pain relief in experienced users.
Common side effects include dry mouth and eyes, reported by a large share of users with high-THC strains in general. At higher doses, transient dizziness or anxiety can occur, particularly in sensitive individuals or those in stimulating environments.
Appetite stimulation is frequently noted within 30–60 minutes, aligning with THC’s known orexigenic effects. Music and tactile experiences often feel richer, while complex tasks or rapid context-switching can feel burdensome under peak effects.
Tolerance builds with frequent use, which can attenuate euphoria faster than body relaxation. Rotating strains and scheduling tolerance breaks of 48–72 hours can restore perceived potency by a noticeable margin for many users.
Potential Medical Applications
Patients often reach for Kosher Kush for sleep initiation and maintenance, given its consistent sedation at typical inhaled doses. In surveys of medical cannabis users, insomnia ranks among the top reasons for use, with many reporting improvements in sleep onset and duration.
Chronic pain is another common target, especially musculoskeletal and neuropathic components that respond to high-THC, myrcene-forward chemotypes. Observational cohorts frequently report clinically meaningful reductions in pain intensity when using THC-dominant flower, often in the 20–30% range compared to baseline.
The strain’s anxiolytic potential is nuanced; low-to-moderate doses may decrease stress reactivity for some, while high doses can provoke unease. Patients with anxiety disorders often benefit from careful titration and pairing with calming routines to avoid overshooting the comfort window.
Appetite stimulation can support patients facing cachexia or nausea, including those undergoing chemotherapy or living with chronic gastrointestinal conditions. THC’s antiemetic properties are well-documented, and limonene’s bright aroma may help with anticipatory nausea for some individuals.
Inflammation-modulating effects may be supported by β-caryophyllene’s activity at CB2 receptors, though the primary relief in this strain is THC-driven. Patients with inflammatory pain sometimes report additive benefits when combining Kosher Kush with CBD-dominant options during daytime.
For sleep, inhaled microdoses of 1–3 puffs 30 minutes before bed often suffice for new patients, scaling to 5–10 mg THC for experienced users. Edible nighttime regimens commonly sit around 5–10 mg THC for beginners, but longer duration can cause grogginess if timing is misjudged.
As with all cannabis-based care, interaction with other medications and individual variability warrant a cautious start-low, go-slow approach. Keeping a brief symptom journal for two weeks can quantify changes in sleep latency, pain scores, and side effects to guide adjustments.
Cultivation Guide: Environment, Training, and Feeding
Kosher Kush thrives in warm, semi-arid indoor conditions with daytime temperatures of 22–26°C in veg and 20–24°C in bloom. Night swings of 2–4°C help harden flowers while limiting botrytis risk.
Target relative humidity of 55–65% in veg and 40–50% in flower, tightening to 38–45% from weeks 6–8 to protect dense colas. VPD in the 0.8–1.2 kPa range during veg and 1.2–1.6 kPa during flower maintains brisk transpiration and calcium flow.
Lighting intensity at 600–800 µmol/m²/s PPFD in late veg and 900–1100 µmol/m²/s in flower maximizes photosynthesis without excessive stress. With supplemental CO₂ at 1000–1200 ppm, growers can push 1000–1200 µmol/m²/s PPFD and expect yield bumps of 10–20%.
Expect 1.5–2.0x stretch; topping once or twice by week 3 of veg combined with a SCROG net creates an even canopy. Defoliate lightly at day 21 and day 42 of flower to open airflow and sunlight pathways without stripping the plant bare.
In coco/hydro, maintain pH 5.8–6.2; in soil, aim for 6.2–6.8 to keep micronutrients bioavailable. EC targets around 1.4–1.8 mS/cm in late veg and 1.8–2.2 mS/cm in peak bloom suit most cuts, with nitrogen sensitivity showing if pushed above 2.3 early.
Nutrient ratios that perform well include higher calcium and magnesium support due to OG lineage demands. A Ca:Mg ratio near 2:1 and total nitrogen taper from 130–160 ppm in late veg to 90–110 ppm by week 7 flower helps avoid leafy buds.
