The craft of solventless

In 2015, we set out to empower the community to make their own hash. A decade later, we press our own. We make the hash we smoke.

Both states,
same high quality

Two coasts.
One craft.

Same wash. Same cure. Two coasts held to one solventless standard. The hash we press is the hash we smoke.

Two tiers. One standard.

Black Label
vs. Green Label

Black chases rare small batches. Green brings the same solventless for the everyday consumer. Same craft. Different tiers.

Black Label
  • Competition-grade hash, washed and pressed for the highest standard
  • Small-batch yields from rare, hand-selected cultivars
  • Limited releases — once it’s gone, it’s gone
Rosin Tech Labs green and black label boxes
Green Label
  • Same solventless standard — uncompromised consistency and quality
  • Highest-yielding cultivars on the market, chosen for performance
  • Wider availability with re-releases you can count on
