Solventless products have become the gold standard for consumers who want purity, flavor, and a true expression of the plant. But not all solventless is created equal. At JAR Cannabis, our  line exists because we believe quality starts long before a wash, a press, or a jar. It begins with how we grow, how we select genetics, and how our team reads resin like a language.

Our Hash Manager, Justin, puts it simply.
“This is where the full circle of our craft comes together.”

Every process, every partnership, and every decision in the JAR Solventless lab is intentional. That intention is what makes us different.

Solventless From a Single Source

Many solventless brands source material from various growers. JAR does not. We are 100 percent single source. Every plant destined for our solventless program is grown in-house, nurtured under controlled conditions, and selected with extraction in mind.

This matters because solventless is unforgiving. If the flower is not exceptional, the hash will not be either. Controlling the entire process from seed to sale gives our team complete oversight of resin quality, trichome development, and overall plant health.

Our collaboration between cultivation and extraction is closer than most operations will ever experience. Justin works directly with Trevor in R&D to run pheno hunts that evaluate new genetics for solventless potential. We do not guess which strains will wash well. We test them. We refine them. We select only the plants that display peak aroma, flavor intensity, and overall resin structure.

This level of alignment means every JAR product begins with genetics chosen specifically for this craft.

A Deeper Level of Resin Understanding

Solventless extraction rewards precision and punishes shortcuts. This is where JAR’s expertise shines.

Before any wash occurs, the team grades trichomes based on ripeness and quality. Ripeness determines cannabinoid and terpene composition. Quality determines how well the resin will separate from the plant material.

Most consumers never see this step, but it is one of the biggest reasons our solventless stands out. Every batch is evaluated for:

• Maturity
• Stability
• Aroma/Flavor
• Oil content
• Color qualities 

This ensures the material entering the lab has the highest potential for melt, flavor, and clarity.

Inside the lab, Devon and the Solventless team wash, collect, and sieve with consistency and care. They are not just running equipment. They are reading the nuances of each harvest and adjusting the process so the final product reflects the plant’s full expression.

Innovation Informed by Tradition

Over the last decade, hash making has transformed. New tools and techniques have unlocked possibilities that did not exist before. JAR Solventless embraces all of it, but we never forget the roots of true hash craft.

Our post-processing represents this balance. We refine techniques to remove lipids and waxes, isolate cannabinoids and terpenes, and create rosin textures and cartridges with clarity and purity that consumers can taste.

At the same time, our team respects the old-world traditions that started the culture of hash in the first place. JAR Solventless is where classic technique meets modern precision.

Expression and Purity You Can Feel

Every jar we release represents the resin qualities of the harvest, not a formula. This is why our textures naturally vary: some batches belong as cold-cured rosin, others are formulated into vape cartridges, and some shine brightest as full-melt or piattella.

By letting the resin guide every decision instead of forcing it into a format, we honor the plant’s true expression. Connoisseurs choose JAR Solventless because you can feel that intention in every dab.

Solventless Crafted for the Connoisseur

At JAR Solventless, we do not frame ourselves as a trend. We frame ourselves as students and stewards of the plant. The care that goes into our process is why our products stand out.

• Single-source from seed to sale
• Genetics selected specifically for solventless
• Select micron-graded trichomes
• Washes performed by trained specialists
• Modern innovation guided by traditional craft
• Unique solventless textures 

This is why JAR Solventless continues to earn trust from consumers who know quality when they see it.

For true connoisseurs, by true hash makers.

At JAR Cannabis, we are excited to introduce Cadillac Rainbow, a hybrid cultivar that brings together standout genetics, complex flavor, and a balanced high perfect for the fall season. As the weather shifts and cozy moments return, Cadillac Rainbow is arriving just in time to elevate your autumn lineup.

A Flavor Profile That Stands Out

Cadillac Rainbow is born from the fusion of Pure Michigan and Runtz, resulting in a layered and memorable flavor. Expect zesty lemon diesel up front, followed by sweet cherry, and finished with a cool hint of mint. The smoke is smooth, gassy, and lingers in a way that keeps you coming back.

Top terpenes include:

• Limonene for bright citrus
• Caryophyllene for warmth and depth
• Myrcene for a relaxed, earthy base
  

Together, they create a sensory profile that makes Cadillac Rainbow a must for connoisseurs who appreciate complexity.

Effects For Fall Slowing Down

Cadillac Rainbow begins with a euphoric lift that clears the mind and brightens the mood. As the high settles, the body melts into a calm, comforting heaviness that encourages relaxation and sparks the appetite. It is a premium pick for unwinding after busy fall days, settling into cooler evenings, or elevating your seasonal rituals.

Limited Fall Drop of Cadillac Rainbow at JAR

Cadillac Rainbow is part of our upcoming fall strain drop, and supplies will be limited. Every batch is grown, hand trimmed, and packaged with intention by our cultivation and R&D teams, ensuring quality that reflects the care we put into all JAR releases.

At JAR Cannabis, every strain, every aroma, and every finished product begins with curiosity, experimentation, and care. Our Research and Development department drives this work, exploring new genetics, refining cultivation methods, and pushing the boundaries of what exceptional cannabis can be. R&D is where science meets intuition, where data meets creativity, and where each season brings new discoveries for our team and our customers.

At the heart of this department is a collective of cultivators who bring diverse experience, perspectives, and passions. Among them is Trevor Brackley, who helps guide R&D efforts with a blend of scientific focus and hands-on growing intuition. Together, the team’s work shapes some of the most beloved JAR Cannabis products on shelves today.

A Culture of Curiosity

R&D at JAR Cannabis was built on a simple idea: never stop exploring. That philosophy mirrors how many cultivators begin. Trevor sprouted his first seeds on a windowsill and tucked early plants among backyard ferns. What starts as curiosity often evolves into a lifelong relationship with the plant.
Within the R&D department, that same spirit drives experimentation and encourages the team to constantly ask what else the plant can do and how its best traits can be brought forward.

Why Trevor Chose JAR Cannabis

When asked what brought him to JAR Cannabis, Trevor says he felt an immediate alignment with the company’s vision. During his interview and facility tour, he noticed the structured, intentional approach to improvement. He saw a place where attention to detail is not just encouraged, but celebrated. It was clear that he would have the space and support to learn, refine his skills, and contribute meaningfully.

“I think my greatest motivators are daily challenges, the team effort, and knowing that the work is never done, and there will always be more to learn,” says Trevor Brackley

A Thoughtful Approach to Innovation

The R&D team at JAR Cannabis believes innovation is most powerful when built on consistency. Instead of making broad changes, the team adjusts one variable at a time so every shift can be clearly measured. This method allows cultivators to detect subtle differences in terpene expression, overall vigor, yield, or sensory qualities. It also helps them make data informed decisions based on both qualitative and quantitative insights. By building from a stable foundation, new breakthroughs emerge naturally and with clarity.

Trends That Drive R&D Forward

Seed selection is one of the most energizing parts of R&D at JAR Cannabis. New genetics bring opportunities to discover fresh combinations of scent, flavor, and effect. Selecting a strain involves balancing customer preferences with plant behavior, production needs, and desired outcomes.

“The trend that excites me most every day is seed selection. There’s nothing like a new fusion of scent, flavor, and effect. A lot goes into choosing a strain. Sometimes it is best to prioritize consumer feedback over plant growth or production. Other times, all the stars align. I enjoy caring for new plants as they begin their journey at JAR, and seeing others find something they love or that helps them,” -says Trevor Brackley

Sustainability is another key driver. The team continually refines LED lighting strategies, irrigation schedules, and environmental controls to conserve both water and energy. In many cases, these improvements also support stronger plant health.

A Look at What’s Ahead in R&D

As the gardens evolve, Trevor remains excited about exploring new cultivars and offering customers fresh sensory experiences. Every strain has the potential to help someone in a meaningful way, and his team is dedicated to nurturing that potential through careful care and selection.

He is also focused on strengthening efficiency across the gardens. Improving processes helps JAR continue to offer premium quality products in a sustainable, scalable way.

What Trevor and The R&D Team Hope Customers Feel

At the end of the day, Trevor hopes people can enjoy JAR Cannabis products knowing they were created with genuine intention. Every plant is grown, harvested, and processed with precision and care. From seed or clone to the moment a customer brings it home, his team works to preserve the truest expression of each cultivar. The goal is always to provide a clean, reliable, and elevated experience.

A Few Cultivars the Team Is Especially Proud Of

Trevor lights up when talking about the ongoing work behind some standout cultivars. Oishii is one of them. It can be finicky and requires extra patience, especially during the clone and veg stages. But the effort has paid off. Oishii shines in both flower and extraction formats, proving that thoughtful cultivation can unlock exceptional potential in even the most challenging varieties.

Mule Fuel and Deep Space are two others that thrive in JAR Cannabis’ environment. Their strong genetics have produced some of the highest yields the team has ever seen, and they have helped streamline maintenance tasks and shorten standard veg times. These cultivars demonstrate how well plants can perform when environmental conditions are dialed in with skill and intention.

Across the board, the R&D team is continuously working to highlight the best attributes of every plant. Through controlled environmental adjustments and data-driven refinement, they help each cultivar move toward its ideal expression.

As cannabis becomes more widely embraced in the wellness and fitness community, runners are discovering what many cannabis users have known for years. THC and CBD can be powerful tools for both body and mind. From easing post-run soreness to enhancing recovery and relaxation, cannabis is emerging as a natural complement to an active lifestyle.

At JAR Cannabis, we’ve seen more athletes turning to our hash rosin topicals and balanced edibles to support their training and recovery. One of them is Erin Winschel, our South Portland Store Manager, who recently crossed the finish line of her first half-marathon.

Erin’s Running Journey: Finding Recovery Through Cannabis

“After getting into running this past year and training for my first half-marathon, I really needed some products to help with muscle soreness,” Erin shared.

Like many runners, Erin found that her training mileage started taking a toll on her muscles and joints. Instead of reaching for traditional pain relievers, she turned to her favorite JAR products: the Hash Rosin Lotion and 1:1 Hash Rosin Gummies to help her recover and unwind.

“The lotion gives immediate, soothing relief with a slight cooling effect,” Erin explains. “Then I’ll take a 1:1 gummy to keep that relief going throughout the night. The gummies are the ideal dosage for me personally. I still get that light THC buzz, but the equal parts of CBD help keep me balanced while easing those running pains.”

For Erin, this routine has become part of her post-run ritual, a blend of physical recovery and mental relaxation that keeps her training sustainable and enjoyable.

The Science Behind Running and Cannabis

Runners often talk about the “runner’s high,” a euphoric state caused by endorphins and the body’s endocannabinoid system (ECS) — the same system that interacts with THC and CBD.

By engaging the ECS through cannabis, runners may experience:

• Reduced inflammation and muscle soreness
• Improved recovery times after long runs
• Calmer sleep and relaxation
• Increased body awareness and mindfulness during movement

Both THC and CBD work synergistically to support recovery:

• THC offers analgesic (pain-relieving) and mood-enhancing effects.
• CBD helps calm inflammation, reduce muscle tension, and promote rest.

In fact, scientific research supports these benefits. A 2023 study published in the Journal of Cannabis Research found that over 90% of participants reported cannabis use aided their exercise recovery and relaxation. read the study here

When paired, like in our 1:1 Hash Rosin Gummies, the combination can help runners recover more naturally and stay consistent in their training.

Our Favorite Post-Run Recovery Pair

Hash Rosin Lotion: A cooling topical designed for immediate relief. Ideal for calves, quads, and sore feet after long runs.

1:1 Hash Rosin Gummies: Balanced with equal parts THC and CBD, offering extended comfort and relaxation that lasts through the evening.

Together, these two make for the perfect runner’s recovery duo,  whether you’re logging your first 5K or training for a marathon.

At JAR Cannabis, we’re proud to support active Mainers like Erin who are discovering how cannabis fits into a healthy, balanced lifestyle. Every product we create,  from our topicals to our edibles, is Made in Maine, Crafted for You, with quality and care in every step of the process.

At JAR Cannabis, our people are what make us who we are, and few embody our culture quite like Justin.

From trimming to growing, to rolling joints and pressing rosin, Justin has truly done it all. After stepping away for a short time, he returned to our Lewiston facility three years ago and has been a cornerstone of the team ever since.

Affectionately known as “Mr. Morale,” Justin brings contagious energy, great music, and plenty of laughs to every shift. But make no mistake: beneath that easygoing attitude is a strong work ethic and laser focus. His dedication keeps operations running smoothly and spirits high across the production floor.

As management puts it best:

“Justin’s energy is contagious and his support for the team is unmatched.”
“He’s truly the heart of the crew!”

Q: How do you maintain your enthusiasm for work?
A: I try keeping the attitude in the room upbeat while keeping the focus on work. Listening to all kinds of music while poking fun at each other.

Q: If you could swap jobs with anyone at the company for a day, who would it be and why?
A: The rosen lab. I loved the process that it takes to make some great products.

Q: Who would play you in a movie about your life?
A: Rob Riggle

We’re thrilled to celebrate Justin’s well-deserved promotion to Assistant Trim Lead, a role that perfectly reflects his leadership, reliability, and commitment to excellence.

Congratulations, Justin! Thank you for bringing your positivity, consistency, and good vibes to JAR every single day.

As the leaves turn golden and the air takes on that familiar crispness, it’s the perfect time to explore the best fall strains in Maine. At JAR Cannabis, our mission is simple: Made in Maine, Crafted for You. Each season we highlight strains that fit the moment, and autumn is all about crisp hikes, cozy firesides, and evenings spent with friends.

This year’s lineup of fall strains blends seasonal flavors with effects that match Maine’s autumn lifestyle. From uplifting sativas that pair with foliage hikes to hybrids that shine around the campfire, here are the strains our staff loves most.

Silver Kush: A Maine Fall Classic

Silver Kush Is a sativa-dominant cross of Silver Bubble and OG #18, and its pine and lemon notes are the perfect match for Maine’s crisp autumn air. The clear-headed, uplifting high provides energy for daytime adventures like foliage hikes, apple picking, or outdoor photography, while larger doses settle into an indica-like calm ideal for cozying up with a movie when the nights turn chilly.

“My favorite fall strain is Silver Kush. The sweet piney flavor and kush notes are perfect for a crisp fall day. The effects are uplifting for the first few puffs which pair great when I’m out in the woods walking my pup. Absolutely my favorite fall ritual given the foliage in Maine. I also enjoy it in the evening as Silver Kush can act like an indica in larger doses given its potency. Perfect for a movie or winding down after a long day.”
— Bob, Store Manager Berwick

Winter Sunset: Firelight and Flavor

Winter Sunset A frosty hybrid created by crossing Chimera with Sugar Cane, is one of the most flavorful fall strains around. Its sweet blueberry and grape notes are layered with hints of pastries, cream, and butter like a seasonal dessert enjoyed fireside. The calm, creative high makes it a go-to for reading by the fire, listening to music, or camping under the stars on crisp nights.

“I find myself reaching for Winter Sunset when I’m outside having a campfire, reading my book.”
— Catherine, Budtender Windham 

“Winter Sunset still gives you the sweetness of summer along with the cool taste of fall. Enjoy while it’s here!”
— Charles, Budtender Berwick 

MAC 1: Adventure and Everyday Rituals

MAC 1 Also known as Miracle Alien Cookies, is famous for its dense trichome-coated buds and spicy citrus diesel flavor. This strain balances a euphoric lift with a relaxing body high, making it versatile for autumn hikes, afternoons in the garden, or watching sports on a Sunday afternoon. Among our fall strains, MAC 1 stands out for both adventure and downtime.

“My fave strain is MAC 1. My fall ritual is hiking with my dog Eddy to the local waterfall, playing some music, and relaxing.”
— Chase, Budtender Carrabassett Valley

“MAC 1 is my go-to for watching sports and tending to the garden once the cooler weather sets in.”
— Jason, Budtender Carrabassett Valley

Deep Space: Cozy Nights and Clear Minds

For evenings when the days grow short, Deep Space (limited release) is one of the best fall strains to help you unwind. A cosmic hybrid of Oreoz x Zero Gravity, it blends sweet cookie richness with diesel funk for a bold autumn flavor. The high starts with a burst of laughter and euphoria before melting into deep body calm—ideal for Halloween movie marathons, blanket cocoons, and slow evenings at home.

“As soon as the air gets cool and crispy, I go for warm and cozy. But that also means it gets darker earlier, which makes me a little sad. So, I really like Deep Space for fall. It lifts my spirits during the day, but also melts away all my tension, making it easier to fully enjoy those evenings of cozy blanket cocoons and Halloween movies without being immediately put to sleep.”
— Christina, Budtender South Portland and Portland 

Devil Driver: Crisp Hikes and Apple Picking

Devil Driver Is an upbeat sativa created by crossing Melonade with Sundae Driver, and it’s tailor-made for fall adventures. Its citrus and tropical fruit punch flavors feel refreshing and bright against Maine’s brisk air, while the motivating high provides the boost you need for apple picking, trail hikes, or tackling seasonal chores. It’s the strain that keeps energy high and spirits lifted, even as the days grow shorter.

“My favorite strain this time of year is Devil Driver. I love to go apple picking at Five Fields Farm in Bridgton and then for a hike at Bald Pate Mountain. Devil Driver keeps me motivated and is a nice sweet treat on the trail!”
— Elisabeth, Budtender Windham

Fall Rituals, Maine Style

Whether it’s hiking to waterfalls, watching sports, sitting fireside with a good book, or catching a movie under a blanket, cannabis makes Maine’s fall moments even more memorable. Each strain brings its own personality; Silver Kush with piney energy, Winter Sunset with cozy sweetness, Deep Space with balanced relief, Devil Driver with motivation, and MAC 1 with versatile vibes for both adventure and downtime.
