Freeze
Flower selected for live rosin is frozen shortly after harvest, preserving the fresh material for the wash rather than sending it through a traditional dry and cure.
Trailhead Solventless · Brainerd, Minnesota
From fresh frozen to live rosin.
Trailhead Solventless follows selected flower from the harvest room into ice-water hash, freeze drying, pressing, and final solventless formats—without hydrocarbon solvents.
The solventless path
Simple ingredients. Demanding execution.
Water, ice, heat, and pressure sound straightforward. The craft is in maintaining clean material, cold conditions, careful handling, and the patience to treat each cultivar as its own batch rather than forcing every wash into the same outcome.
Inside Trailhead Solventless
Watch the process.
Ice-water washing separates the resin heads. Freeze drying removes moisture. Controlled heat and pressure finish the material as live rosin—all inside our Brainerd operation.
Vertical field video · 30 seconds · On-screen captions includedWash
Cold water and controlled agitation separate resin heads from the fresh-frozen plant material. The collected grades become ice-water hash.
Dry
The wet hash is carefully freeze-dried to remove moisture while protecting the material for pressing and finishing.
Press
Controlled heat and pressure transform the dried hash into live rosin. The finished batch may be prepared for jars or rosin vapor hardware.

The lab and cultivation teams work in the same Brainerd operation. That proximity helps the team choose material intentionally and carry the story of the cultivar into the finished rosin or vapor.
Questions from the trail
Solventless answers.
What does solventless cannabis mean?+
Solventless concentrates are produced through mechanical separation methods rather than hydrocarbon solvents. Trailhead Solventless live rosin uses ice water, freeze drying, heat, and pressure.
What is fresh-frozen cannabis?+
Fresh-frozen cannabis is harvested flower that is frozen shortly after cutting instead of being dried and cured. It is commonly used as the starting material for live rosin.
How is ice-water hash made?+
Ice-water hash is made by using cold water and agitation to separate resin heads from cannabis plant material, then filtering and collecting the resulting hash.
Does Trailhead make live rosin in Minnesota?+
Yes. Trailhead Solventless produces live rosin and rosin vapor products in Brainerd from selected Minnesota-grown flower.
