Why solventless
Nothing added. Everything preserved.
What solventless means
No butane, propane, ethanol, or CO₂. Ice water agitation, filtration, pressure, and controlled heat separate the trichomes from the plant — the finished product is the plant’s own resin, nothing else.
Terpene preservation
Terpenes carry a cultivar’s scent and flavor. Minimal, cold processing means more of those compounds survive into the finished product — which is why harvest timing, rapid freezing, and gentle handling run through our whole process.
Flavor consumers can tell apart
Solventless concentrates read closer to the original flower: richer aroma, cleaner taste, more distinct cultivar character.
Clean extraction
The full input list: ice, water, filtration, pressure, controlled heat. A process simple enough to explain in one sentence — and to stand behind.

Questions
Before you send material.
Do you accept fresh frozen?
Yes — fresh frozen is our preferred input for ice water extraction.
Do you process cured flower?
Yes.
Can I keep strains separate?
Yes — single-source runs are standard, and blending is available when you want it.
How long does processing take?
It depends on the schedule and the finished product required — we confirm timing during consultation.
Can I receive loose hash or finished rosin?
Rosin, yes. We’ll confirm loose hash options for your product mix during consultation.
Who owns the finished product?
That depends on the agreement — toll processing and white-label structures are both available.
How are yields calculated?
Based on finished product.
