Where purity begins.
At Rosslyn, everything starts with the plant.
We source only the highest quality flower — fresh frozen at harvest, never dried, never trimmed.
Our partners are small-batch cultivators who care as deeply as we do.
Clean inputs, no pesticides, and genetics chosen for flavor, effect, and resin production.
From there, it’s ice, water, and time.
We separate the trichomes gently — without solvents, additives, or shortcuts.
What’s left is full-spectrum hash, pressed into cold-cured rosin, and crafted into wellness-forward formats.
No mystery. No middlemen.
Just purity, from source to experience
From the Source
Core of Calm
Like a gentle stream, we follow nature’s path—unrushed and unaltered. Using only chilled water, we carefully wash freshly harvested cannabis to preserve its purest form. The result is our live rosin: full-spectrum, solventless, and true to the plant in every drop.
