The craft of solventless

We started in 2015 showing heads how to press their own. Ten years later we press it ourselves, and we don’t put out anything we wouldn’t smoke.

What we press.

Black Label Rosin, solventless rosin by Rosin Tech Labs, California packaging

Black Label Rosin

Black Label is our rare, small-batch line. Single farms, limited runs. Most batches come in under 1,000 grams. When a drop sells out, that’s usually it, give or take a few that earn a comeback. We only press it with the rarest cultivars our partner farms grow.

Green Label Rosin, solventless rosin by Rosin Tech Labs, California packaging

Green Label Rosin

Green Label is the same solventless craft, built for every day. Same wash, same press. We just source our more available cultivars in bulk and pass the savings on. Real hash at a price you can run with.

Hash Hole, solventless infused pre-roll by Rosin Tech Labs, California packaging

Infused Pre-Roll

Hash Hole

Strain-specific, small-batch, hand-rolled on site in Torrance, CA. 1.3g of indoor flower around .3g of Black Label rosin, wrapped in Vibes Black Paper with a glass filter to cool the smoke. We sample every batch before it goes out.

Rosin Vape, solventless all-in-one solventless vaporizer by Rosin Tech Labs, California packaging

All-in-One Solventless Vaporizer

Rosin Vape

An all-in-one solventless vape with the loudest terps we make. We dialed the cure first, then built it into the hardware. Small-batch, strain-specific, rosin on the go.

Rosin Gummies, solventless edible by Rosin Tech Labs, California packaging

Rosin Gummies

Strain-specific flower, washed to hash, then made into a gummy. Vegan, non-GMO, and the terps actually taste like the strain they came from. Clean and simple.

Hash Nugs, solventless infused flower by Rosin Tech Labs, California packaging

Hash Nugs

Flower infused with our in-house solventless ice water hash. Grind it into papers or pack a bowl. Every jar is pure solventless, start to finish.

Hash Walkers, solventless infused joint pack by Rosin Tech Labs, California packaging

Infused Joint Pack

Hash Walkers

A six-pack of .5g joints: 80% flower, 20% award-winning ice water hash. Smooth, potent, and easy to pass around.

Hash Joint, solventless infused pre-roll by Rosin Tech Labs, California packaging

Infused Pre-Roll

Hash Joint

A single 1g joint: 80% flower, 20% pure ice water hash. Smooth, potent, and full of flavor.
