Description
Coldfire Carts and Juice Bar Disposable
Coldfire carts are 1-gram 510 cartridges from ColdFire Extracts, a Southern California brand that calls its oil Juice, its carts Juice Carts and its all-in-one pens Juice Bars. This listing covers both: the 1G Juice Cart in cured and live resin, and the 0.5G Rosin Juice Bar disposable.
Both are $20 each here. Choose the format, set the quantity, then take mixed flavors or tick your own.
Who makes Coldfire Extracts
ColdFire is the trading name of Greenmount LLC, a California company founded by Zaid Jadan and Steven Daoud, which has used the ColdFire name since 2020 and calls itself family-owned. It sells through licensed California dispensaries in Los Angeles, San Diego, the Bay Area and Sacramento, and its Weedmaps listing carries manufacturing license DCC-10002322. New flavors drop every Friday at 7 p.m. Pacific, most of them limited runs with named California growers.
What is in a Coldfire cart and Juice Bar
- Juice Cart: 1G, 510 thread, full ceramic cartridge
- Cured resin cart: 5 to 10% terpenes, per ColdFire
- Live resin cart: 10 to 15% terpenes, per ColdFire
- Rosin Juice Bar: 0.5G solventless live rosin all-in-one
- Additives: no distillate, cutting agents or botanical terpenes, per ColdFire
- Battery advice: 1.9 to 2.4 volts for the carts
The carts are hydrocarbon resin, extracted in-house in a single pass below minus 100 degrees Fahrenheit, according to the company. Only the Juice Bar is rosin: solventless, made with ice water, heat and pressure.
Coldfire cart flavors
ColdFire releases dozens of carts a month, so no list stays current. These were the most widely stocked in the drop for the week of October 5, 2026. Names with “Live” in brackets are live resin. Everything else is cured resin.
Graype, Sonic Fuel, Arctic Gummies (Live), Why So Grapey (Live), Lemon Kool Whip, Black Maple Zuava (Live), Cherry Krypto, Cosmic Nectar (Live), GSC, PB & Jane, Zoap, Maria Poppins (Live), Verzace, Rude Boy x Badman.
Coldfire Rosin Juice Bar flavors
Juice Bars drop about two at a time every few weeks. Recent releases: Gasnana, Super Sour, Lemon Up, Spritzer, Banana Riddles, Space Cheese.
ColdFire does not label its strains indica or sativa, and Weedmaps tags nearly all of them hybrid by default, so we have left the labels off.
How to use Coldfire carts and the Juice Bar
Screw the cart onto any 510 battery and keep it between 1.9 and 2.4 volts, as ColdFire advises. Higher voltage burns the terpenes the oil is sold on. The Juice Bar is draw-activated, so inhale to use it. Start with a short pull on either and wait a few minutes.
Coldfire vs Flavorade
The founder of Flavorade carts, Nick Coburn, says he built the ColdFire cart line at Greenmount before leaving in 2023. Greenmount later sued him, and a federal court dismissed its claims with prejudice in April 2025, according to Ganjapreneur. Both brands sell strain-specific resin carts with no distillate on a weekly drop cycle. For a live resin-only cart from the same scene, see Vuze carts. All our carts are on the cannabis cartridges page.
FAQ
Are Coldfire carts rosin?
No. The carts are cured or live resin. The 0.5G Juice Bar is the only ColdFire product made with rosin.
Why is the Juice Bar half a gram?
Solventless rosin yields far less oil per pound of flower than resin, which is why rosin pens usually come in smaller sizes.
What battery fits a Coldfire cart?
Any 510-thread battery. ColdFire also sells its own draw-activated Juice Straw battery.
