ColdFire Extracts has become one of the top brands in California’s competitive cannabis industry. ColdFire has a strong reputation for maintaining real strain flavors through a proprietary method of extracting cannabis. ColdFire believes in “flavor first” which has helped establish loyalty from connoisseurs.
Founded by extraction expert Nick Coburn and his family in late 2020, ColdFire has dedicated themselves to the quality of the product over the design of the product. ColdFire has had success in the vapor pen space with consistently being in the top 10 vapor pen brands in California since mid 2025.
The ColdFire Flavor Philosophy: "Flavor Speaks Louder Than Words"
This motto is more than marketing – it is how they do business. ColdFire dedicates time and money to the quality of the oil inside the cartridge, not the look of the packaging. As a result, many people have described the experience of using ColdFire products as a “Michelin Star-rated experience”. By working with the top-tier California growers such as Blem, Lumpy’s and Green Dragon, ColdFire ensures they work with the highest-quality starting material. The end result is a unique taste that truly represents the original plant.
The ColdFire Extraction Method
The reason ColdFire products have such great flavor is due to a cryogenic extraction process. ColdFire uses 100% butane at temperatures less than -100°F to flash freeze the cannabis plant material. The extremely low temperature used in this process is crucial. The temperature helps to preserve the delicate terpenes and cannabinoids that are often broken down or destroyed during typical extraction methods. ColdFire products are all natural extracts without added distillates, cutting agents or color remediation agents. Lab results, such as the Gelato OG cart having 6.4% terpenoids, demonstrate the high levels of terpenes that ColdFire claims to be present in their products.
Comparing Cured Resin, Live Resin & Rosin
ColdFire has three different types of extract available, each offering a unique experience:
- Cured Resin Juice Cartridges: These are ColdFire’s flagship products. They are made from cannabis that has been allowed to dry and cure post-harvest. The curing process allows the cannabis to develop deeper and more complex flavors. This is their most popular and well-received line of products.
- Live Resin Cartridges: These are created from freshly harvested plant material that is immediately frozen. This allows the bright and vibrant terpene profile of the living flower to be preserved.
- Rosin Disposables: A solventless option made using heat and pressure. This is an appealing option for those looking for a product made without any chemical extraction agents.
Top Rated ColdFire Cured Resin Strains
Several strains stand out as being some of the top rated based on market data and user reviews. The ColdFire x Blem - Unruly OG Cured Resin Juice Cartidge was the #1 selling product for multiple months in 2025. Other popular strains include:
- Super Runtz: Known for its sweet, candy-like aroma with fruity undertones and balanced, euphoric effects.
- Cherry Dough: Provides a unique profile of fresh baked cookies mixed with ripe cherries, provides relaxing yet uplifting effects.
- Limited Run Collaborative Strains: Due to their limited availability, these strains are highly sought after for their unique genetic makeup.
ColdFire's Market Performance and Popularity
ColdFire has a strong standing in terms of sales. According to California’s Vapor Pens category, ColdFire consistently placed between 5th and 8th from July to October 2025. Although sales declined from around $3.7 million to $2.6 million during that period, the fact that ColdFire has consistently placed in the top 10 in a crowded market is significant. The data indicates that ColdFire has a solid base of support from enthusiasts however faces stiff competition from other large players such as Heavy Hitters and Jeeter.
The Hardware: Design, Smoothness, and Quality
While the oil in the cartridge is important to the overall experience, the hardware is also important. ColdFire uses premium ceramic cartridges that are engineered to allow for low-temperature vaping. Based on my own experiences with the cartridges, this design makes for extremely smooth hits with very little harshness. The design of the cartridges allows for reliable and consistent vapor production and prevents leaks. The 0.5g disposable options offer the same quality as the cartridges in a convenient and easy-to-use package.
Pricing, Packaging, and Value Proposition
ColdFire carts fall under the premium price point. The money spent on ColdFire carts is going towards the advanced extraction process, high terpene content, and collaborative genetics. The packaging is minimalist – some would say boring. However, this is part of ColdFire’s intentional decision to put all the money in the product, not the packaging. I think the value proposition is reasonable for someone looking for a flavor-first experience. It is an investment in a superior sensory experience versus a delivery system of cannabinoids.
How to Use and Store ColdFire Carts
To get the best experience from ColdFire carts:
- Attach the cartridge to a compatible battery. For optimal flavor, set your vape to a low voltage (around 2.2V - 3.0V). Take slow and deep draws to fully appreciate the full flavor profile.
- Store cartridges in an upright position in a cool, dark location. Do not expose cartridges to heat or sunlight to preserve the potency and flavor.
- Designed to work with standard 510 threaded batteries, however, using a good quality, variable voltage pen will help improve performance.
Final Verdict: Are ColdFire Carts Worth It?
If you consider yourself a flavor-first type of person, then yes, ColdFire carts are definitely worth trying. ColdFire is able to live up to their claims of unmatched flavor and smoothness due to their science-backed technology and innovation. The high terpene content creates a rich and full-spectrum experience that feels true to the original strain.
They may not be for everyone though. If your number one priority is getting the highest amount of THC possible at the lowest cost, there may be other distillate-based options that make sense. Some people may also find the minimalist packaging lacking in appeal if you like branding and visual aesthetic.
In the end, ColdFire has found a niche as the go-to option for people who feel that flavor is number one. In a crowded marketplace, ColdFire has established a baseline of quality that is representative of what premium California cannabis should taste like.
