The Leiffa Legacy: Pioneers in Solventless Rosin Extraction

Solventless isn’t a trend; it’s our standard. See how Leiffa has shaped hash rosin and brought a wide variety of solventless to Colorado since 2018.

Our Early Days: Crafting Solventless Before It Was Trendy

Long before rosin was trendy, we were washing, pressing, and dialing it in. When we started Leiffa back in 2018, solventless was still finding its footing in a market that was chasing the next big thing. We saw things differently. We were incredibly fortunate in those early days to work alongside extractors trained by Nikka T., one of the original pioneers of the solventless movement. His influence helped us build a foundation of craft and integrity from day one, a commitment to doing things the right way, even when it wasn’t the easiest way.

Overcoming Challenges: Innovating Solventless Rosin Extraction

In those humble beginnings, our crew set out to redefine what was possible in solventless extraction. We didn’t have big investors or shiny equipment. Just a small, passionate team willing to get our hands (and sometimes feet) cold and wet. That meant hauling endless bags of ice into the washroom by hand, paddling thousands of grams of fresh frozen with the same care and attention every single time. Every challenge was an opportunity to find creative, resourceful solutions.

When we were just starting out, the pre-made equipment available at the time was either lackluster or not built for true commercial scale. Back then, Harvest Right freeze dryers were mostly in kitchens, not washrooms, we doubt they were getting many calls from hash makers.

More often than not, when a tool didn’t exist, we retrofitted something else to get the job done. And when a process could be improved, we improved it. We spent countless hours refining our craft through trial and error. But we didn’t do it alone. We leaned on feedback from other hash makers, listened closely to what our community wanted, and stayed connected with the people actually consuming our hash.

Collaborations That Elevated Our Craft

As we grew, we maintained our hands-on, scrappy approach but recognized the need for partners who shared our values. We were among the first to collaborate with LowTemp Industries, a team as committed to clean, precise hash as we are. Our partnership went beyond using their equipment — we worked closely with them on R&D, helping to test and refine new tools and processes.

When it was time to scale our washes, we brought in an Osprey to handle the heavy lifting. It made the process cleaner and more consistent than the early DIY setups could ever achieve. By combining smart technology with our old-school dedication, we stayed true to the craft to deliver more hash with less hassle.

Solventless for Everyone: Infused Joints, Rosin Vapes, and Chocolate Bars

Early on, we realized that consumers enjoy variety. Whether it’s the ritual of sparking a joint to end the day or the trusted nostalgia of a decadent yet powerful edible, variety adds a little spice to consumption. Sometimes we indulge alone and other times amongst friends.

From our very first years, we have been dedicated to perfecting a diverse lineup of infused joints, chocolate bars, and rosin vapes. Each product is created to deliver the same clean, solventless experience our community expects, while offering different ways to enjoy cannabis depending on mood, occasion, or preference.

Expanding into Pennsylvania: Serving the Medical Cannabis Community

Having established a strong foundation in Colorado, we’ve extended our commitment to the medical cannabis market in Pennsylvania. From our humble beginnings operating a dedicated medical dispensary, serving patients has always been at the heart of what we do. Our mission is to provide patients with dependable, high-quality options, upholding the same standard of solventless quality and consistency that has always been our hallmark.

Our expansion into Pennsylvania underscores our dedication to accessibility, ensuring patients can readily obtain trusted solventless concentrates, rosin vapes, and sublingual products, all crafted with the integrity synonymous with our brand. Supporting Pennsylvania’s medical cannabis patients is part of our commitment to keep solventless accessible to everyone who needs it most.

Our Commitment: Solventless as the Standard

Today, “solventless” has become a buzzword, a trend, and a checkbox for many. But for us, it has never been a fad; it is our standard and our roots. We believe that when you keep things clean and honor the plant, the results speak for themselves. This work has never been about hype; it is about longevity and building trust with the plant, the process, and every person who chooses one of our solventless products. We continue pushing forward, committed to providing a solventless experience accessible to everyone, no matter their preferred form of cannabis.
