About the Oil
Brass Knuckles uses a solvent-based extraction process to achieve 90%+ THC concentration. The oil is then blended with strain-specific terpenes. This gives each cart a distinct flavour and effect rather than a generic profile.
The ceramic coil is important. Metal coils can alter the flavour of oil at higher temperatures. Ceramic heats more evenly and does not react with terpenes. Each draw tastes clean from the first puff to the last.
However, this oil is not live resin or liquid diamonds. It does not preserve the full-spectrum terpene profile of fresh cannabis. For extract types with greater complexity, see our live resin vapes UK and liquid diamonds vapes UK collections.
Brass Knuckles Strain Profiles and Terpene Guide
Each Brass Knuckles cartridge is named after a specific cannabis strain. The terpene profiles below are based on established strain genetics and publicly available brand information. Where not verified by a batch COA, profiles are marked as estimated.
OG Kush — Indica-Dominant Hybrid | Terpenes: Myrcene, Limonene, Caryophyllene
OG Kush crosses Chemdawg with Hindu Kush and Lemon Thai genetics. It produces an earthy, piney aroma with a lemon-fuel undertone. Myrcene leads the terpene profile, producing sedating and body-heavy effects. Limonene adds a citrus brightness. Caryophyllene rounds the profile with spiced, stress-relieving depth.
Effects are relaxing and euphoric, with a strong body component. Best for: evening use, stress relief, pain management, and experienced users who know OG genetics. Terpene profile: estimated.
Gelato — Hybrid | Terpenes: Caryophyllene, Limonene, Myrcene
Gelato crosses Sunset Sherbet and Thin Mint GSC. The flavour is sweet, creamy, and dessert-like with a berry and citrus edge. Caryophyllene leads the effect — stress relief and physical warmth. Limonene adds uplifting brightness. Myrcene deepens the relaxation without pushing into full sedation.
Effects are balanced and euphoric. Gelato suits social sessions, creative work, and early evening use. It is one of the most approachable strains in the range. Best for: social use and users who prefer balanced effects. Terpene profile: estimated.
Strawberry Cough — Sativa | Terpenes: Terpinolene, Myrcene, Caryophyllene
Strawberry Cough traces to Haze and Strawberry Fields lineage. The flavour is distinctly sweet strawberry with a floral, herbal finish from terpinolene. Terpinolene leads the uplifting, creative effect. Myrcene adds mild body warmth. Caryophyllene provides a subtle spice on the exhale.
Effects are energising and cerebral. First-time users should start with a single short draw — it hits faster than most sativas at 90%+ THC. Best for: daytime use, focus, and creative sessions. Terpene profile: estimated.
Sour Diesel — Sativa | Terpenes: Caryophyllene, Limonene, Myrcene
Sour Diesel descends from Chemdawg 91 and Super Skunk. The flavour is sharp and pungent — diesel fuel with a sour citrus edge and earthy exhale. Caryophyllene leads the energising, stress-relieving effect. Limonene adds mental clarity and mood elevation. Myrcene softens the experience with mild body warmth.
Effects are fast-acting and productive. Sour Diesel is not a relaxing strain — it is for active use. It is not recommended for users sensitive to anxiety at high THC doses. Best for: daytime productivity and experienced sativa users. Terpene profile: estimated.
Blue Dream — Sativa-Dominant Hybrid | Terpenes: Myrcene, Pinene, Caryophyllene
Blue Dream crosses Blueberry indica with Haze sativa. The flavour is sweet and blueberry-forward with a fresh herbal finish from pinene. Myrcene leads the relaxing body warmth that prevents the anxious edge of pure sativas. Pinene contributes mental clarity and focus. Caryophyllene adds mild stress relief.
Effects are gently uplifting and gently relaxing in equal measure. Blue Dream is one of the most accessible strains in the range. Best for: daytime use, beginners to high-THC carts, and users who want balance without sedation. Terpene profile: estimated.
Granddaddy Purple — Indica | Terpenes: Myrcene, Caryophyllene, Linalool
Granddaddy Purple crosses Purple Urkle and Big Bud. The flavour is deeply sweet — grape, berry, and a floral earthy undertone from linalool. Myrcene leads a heavily sedating, full-body effect. Caryophyllene adds anti-inflammatory and stress-relief properties. Linalool brings a calming, floral depth that makes this one of the brand’s strongest sleep-support strains.
Effects are deeply sedating and physically heavy. This is an evening and nighttime strain only. Best for: sleep support, chronic pain management, and deeply relaxing sessions. Not recommended for daytime use. Terpene profile: estimated.
GSC (Girl Scout Cookies) — Hybrid | Terpenes: Caryophyllene, Limonene, Linalool
GSC crosses OG Kush and Durban Poison. The flavour combines sweet, minty cookie notes with earthy undertones and a spiced exhale. Caryophyllene leads the stress-relieving and physically relaxing effect. Limonene adds mood elevation and citrus brightness. Linalool deepens the calming profile with anti-anxiety properties.
Effects are euphoric and deeply relaxing. GSC leans more indica than sativa in practice. Best for: evening unwinding, stress management, and appetite stimulation. Terpene profile: estimated.

How to Use Brass Knuckles Vape
What You Need
Brass Knuckles is a cartridge, not a disposable. You need a separate 510-thread battery to use it. The Brass Knuckles branded battery is compatible, but any standard 510-thread battery works. Screw the cartridge clockwise onto the battery — finger-tight only. Do not overtighten.
Voltage Settings
Most 510 batteries offer variable voltage. Use these settings for Brass Knuckles carts:
- 2.4V–2.8V (Low): Best flavour, cooler vapour, lighter effect
- 3.0V–3.2V (Medium): Balanced flavour and vapour — recommended starting point
- 3.4V–3.8V (High): Maximum vapour, reduced flavour, stronger onset
Do not exceed 3.8V. Higher voltage burns the oil faster than the ceramic coil can vaporise it evenly. This causes a harsh, burnt taste and wastes oil. Start at medium and adjust.
Dosing Guide
Start low. Brass Knuckles at 90%+ THC is significantly stronger than most vape pens.
| Experience Level | Starting Dose | Wait Time | Expected Effect |
|---|---|---|---|
| First time | 1 puff (2 seconds) | 20–30 minutes | Mild relaxation or uplift |
| Occasional user | 1–2 puffs | 15 minutes | Moderate, clear effect |
| Regular user | 2–3 puffs | 10 minutes | Comfortable, functional session |
| Experienced user | 3–5 puffs | 5 minutes | Strong, long-lasting effect |
| High tolerance | 5+ puffs | As needed | Intense, prolonged session |
Safety note: THC at 90%+ is significantly stronger than most products. If the effect feels too intense, sit down, drink water, and eat something. The effects are temporary and will pass. Do not drive after use. Keep away from under 18s. Do not use if pregnant or if you have a history of psychosis or cardiovascular conditions.
Troubleshooting
- Clogged cart: Warm the cart between your palms for 60 seconds, then try a short gentle draw. Low voltage settings also help with thick oil.
- Burnt taste: Reduce voltage immediately. Do not exceed 3.8V with Brass Knuckles carts.
- Weak vapour: Check battery charge level. Increase voltage slightly if battery is full.
- Leaking: Store the cart upright at all times. Do not store on its side or in extreme heat.
How to Verify Your Brass Knuckles Cart Is Authentic
Brass Knuckles is one of the most counterfeited cannabis brands in the world. Fake carts have been found to contain harmful cutting agents including vitamin E acetate. Always verify before use.
- Check the holographic sticker. Genuine packaging has a holographic foil sticker that shifts colour and pattern when tilted. A flat, non-shifting sticker indicates a counterfeit.
- Scan the QR code. Every authentic cart has a QR code on the packaging. Scan it — it must redirect to brassknucklesbrand.com and show a matching batch result. Any other domain or a blank result indicates an unverified product.
- Inspect the cartridge. A genuine Brass Knuckles cart has a gold-coloured metal tip, clear borosilicate glass body, and white ceramic mouthpiece. The oil should be clear to light amber and move slowly when tilted.
- Check the thread connector. The 510-thread connector should be smooth, evenly threaded, and stamped with the brand logo. Rough threading or no logo are counterfeit signs.
- Check the first draw. Genuine Brass Knuckles oil tastes clean and strain-accurate immediately. A chemical or artificially harsh flavour on the first puff is a warning sign.
If any check fails, do not use the product. Contact CaliVape at support@calivape.co.uk with photos. We verify every batch before dispatch.

Brass Knuckles suits buyers who want high-THC oil in a well-known, widely-verified format. The brand’s recognition is a genuine advantage — its authentication infrastructure is more developed than many competitors precisely because it has been fighting counterfeits since 2016. If live resin flavour matters more than raw THC%, Raw Garden is worth considering. However, for potency and brand trust combined, Brass Knuckles is hard to beat at this price.

Frequently Asked Questions — Brass Knuckles Vape UK
Is Brass Knuckles a real brand?
Yes. Brass Knuckles Brand is a legitimate California cannabis company established in 2015. It sells across licensed US dispensaries and is recognised for its distinctive gold-tipped cartridges and black-and-gold packaging. However, it is one of the most counterfeited cannabis brands globally. Always verify the QR code and holographic sticker before use. CaliVape stocks only verified authentic Brass Knuckles products sourced from approved UK distributors.
What battery does Brass Knuckles use?
Brass Knuckles carts use a standard 510-thread connection — the most common thread type for vape batteries worldwide. They are compatible with virtually any 510-thread battery. The Brass Knuckles branded battery is designed to work optimally with these carts. However, any quality 510-thread battery with variable voltage in the 2.4V–3.8V range works well. Start at medium voltage (3.0V–3.2V) for the best balance of flavour and effect.
How strong are Brass Knuckles carts?
Brass Knuckles claims 90%+ THC across its range. This is significantly stronger than standard distillate carts, which typically reach 70–85% THC. First-time users and anyone with low tolerance should start with a single 2-second puff and wait at least 20 minutes before taking more. To confirm the exact THC% for your specific batch, email support@calivape.co.uk with your order number.
How many puffs does a Brass Knuckles 1G cart give?
A 1G Brass Knuckles cartridge delivers approximately 300–400 puffs based on standard 2–3 second draws at medium voltage (3.0V–3.2V). Longer draws and higher voltage settings use more oil per puff and reduce the total count. The borosilicate glass body allows you to monitor the remaining oil visually.
How do I verify my Brass Knuckles cart is authentic?
There are five steps. First, check the holographic sticker — it must shift colour and pattern when tilted. Second, scan the QR code — it must redirect to brassknucklesbrand.com with a matching batch result. Third, inspect the cartridge — gold metal tip, clear glass body, white ceramic mouthpiece, and clear to light amber oil that moves slowly. Fourth, check the 510-thread connector for the brand stamp and even threading. Fifth, check the first draw — genuine Brass Knuckles oil tastes clean and strain-accurate immediately. Contact CaliVape if any step fails.
Are Brass Knuckles carts safe to use?
CaliVape requires a Certificate of Analysis from an independent laboratory for every product listed. The COA verifies THC%, CBD%, and screens for residual solvents, heavy metals, pesticides, and microbial contamination. Counterfeit Brass Knuckles carts have historically contained dangerous cutting agents — this is why verification before use is essential. Every cartridge at CaliVape is sourced from verified distributors and batch-checked. Request your COA at support@calivape.co.uk with your order number.
What strains are available in Brass Knuckles at CaliVape?
Brass Knuckles is available at CaliVape in seven strain profiles: OG Kush, Gelato, Strawberry Cough, Sour Diesel, Blue Dream, Granddaddy Purple, and GSC (Girl Scout Cookies). Each strain uses terpenes that reflect the character of the named cultivar. OG Kush and Granddaddy Purple suit evening use. Blue Dream, Gelato, and Strawberry Cough suit daytime use. Sour Diesel is best for experienced users seeking a productive sativa. Current stock is shown in the variant selector on this page.
What voltage should I use for Brass Knuckles carts?
Start at medium voltage (3.0V–3.2V) for the best balance of flavour and vapour. Low voltage (2.4V–2.8V) gives the cleanest flavour but lighter vapour. High voltage (3.4V–3.8V) produces more vapour and a stronger onset but reduces flavour quality. Never exceed 3.8V — this burns the oil and damages the ceramic coil, producing a harsh taste and wasting the remaining oil.
What is the difference between a Brass Knuckles cart and a disposable vape?
Brass Knuckles is a cartridge — it contains 1G of THC oil and screws onto a separate 510-thread battery that you purchase separately. A disposable vape is an all-in-one device with a built-in battery and pre-filled oil that you discard when empty. Cartridges give you more control over voltage settings and let you use the same battery across multiple carts. Disposables are more convenient but offer less hardware control. If you do not have a 510 battery, see our disposable vape range.
Why is my Brass Knuckles cart clogging?
Clogging is common with high-viscosity THC oil, especially in cold environments. The oil thickens and can block the airflow channel. To clear a clog, warm the cartridge between your palms for 60 seconds, then take a short, gentle draw without activating the battery. Alternatively, use the preheat mode on your battery if it has one — this sends a brief low-heat pulse through the coil to liquefy the oil. Store carts upright and away from cold temperatures to reduce clogging.
Can I get a COA for my Brass Knuckles cart from CaliVape?
Yes. Email support@calivape.co.uk with your order number and the batch number from your packaging. We will send the Certificate of Analysis for that specific batch within 24 hours. The COA confirms THC%, CBD%, and screens for residual solvents, heavy metals, pesticides, and microbial contamination.
What is the delivery time for Brass Knuckles Vape UK?
Orders placed before 2PM are dispatched the same day from CaliVape’s UK warehouse. Delivery is next working day across the UK. All orders arrive in plain, unbranded packaging — no product names or brand logos visible on the outside. A tracking number is included with every order.
