Cold cured live rosin (90u)

Overview & The 90-Micron Solventless Separation Science In mechanical trichome harvesting, not all resin glands are created equal. Trichomes between 25u and 70u often contain higher ratios of stalks and immature resin heads, while trichomes larger than 120u can include ruptured membranes and vegetative debris. The 90-micron sieve fraction (specifically the 73u–119u band, centered on 90u) isolates only fully developed, intact capitate-stalked trichome heads containing optimal ratios of phytocannabinoids, monoterpenes, and flavonoids.

The extraction and curing process adheres to clinical solventless protocols:

Cryogenic Ice-Water Separation: Fresh-frozen cannabis colas are washed in certified medical ice-water wash vessels. Chilled water hardens the trichome cuticles, allowing them to snap cleanly from their stalks without breaking plant cell walls or releasing water-soluble chlorophyll.
Freeze-Drying & Low-Temp Hydraulic Pressing: The collected 90u resin is freeze-dried under deep vacuum to sublime moisture without heat. It is then double-bagged in food-grade pharmaceutical mesh and pressed on pneumatic plates at ultra-low temperatures ( $65^\circ\text{C}$ to $78^\circ\text{C}$ ) to express uncut rosin nectar.
The 21-Day Cold Cure (Badder Transformation): The fresh-press rosin is sealed inside inert glass vessels in complete darkness at $10^\circ\text{C}$ to $14^\circ\text{C}$ . Over three weeks, THCa nucleates into microscopic crystal lattices while native terpenes separate and rise as a viscous liquid layer. Gentle mechanical agitation (whipping) creates a uniform, shelf-stable, scoopable badder that will not dry out or shatter at room temperature.

Sensory & Inhalation Rheology Breakdown

Aroma & Terpene Expression: Unopened jars emit an intense, true-to-the-living-plant fragrance. Depending on the cultivar washed, top notes feature zesty lime peel, macerated tropical passionfruit, ripe guava, or sharp chemical fuel, grounded by rich cream and dough undertones.
Palate & Aerosol Cleanliness: Aerosolized through a clean quartz banger or medical ceramic vaporizer at low temperatures ( $175^\circ\text{C}$ to $200^\circ\text{C}$ ), the vapor melts cleanly without residue, charring, or blackened carbon spots, leaving an enduring botanical aftertaste on the palate.
Texture & Handling: Wet, glistening butter-paste consistency. It remains pliable and adheres effortlessly to titanium, glass, or stainless-steel dab tools without crumbling or running.

European Compliance, Quality Assurance & B2B Logistics

EU-GMP Cleanroom Processing & Packaging: Washing, freeze-drying, hydraulic pressing, and cold-curing are carried out inside ISO Class 6 and 7 cleanroom suites operating under strict pharmaceutical Good Manufacturing Practice, guaranteeing zero airborne particulates, spores, or microbial contamination.
Inert Barrier Glass Packaging: Dispensed in pharmaceutical-grade violet/amber UV-blocking glass jars equipped with food-contact PTFE (Teflon) lid liners and child-resistant closures (ISO 8317 certified). The PTFE seal prevents volatile monoterpenes from degrading exterior plastics and eliminates oxidation during storage.
Non-Narcotic European Transit Classification: Because the formulation consists of unheated, non-psychoactive THCa with active Delta-9-THC verified below 0.20% w/w in its distribution state, it qualifies as non-controlled botanical concentrate eligible for standard commercial B2B transport throughout the Schengen territory.
Accredited Laboratory Analytics: Every wholesale lot is accompanied by ISO/IEC 17025 accredited Certificates of Analysis (CoAs) validating cannabinoid percentages, full gas chromatography terpene profiles, pesticide clearance, heavy metal limits, and microbiological sterility.
Continuous Cold-Chain Logistics: Stored and dispatched under temperature-controlled cold-chain conditions ( $2^\circ\text{C}$ to $6^\circ\text{C}$ ) in insulated shipping containers equipped with validated digital temperature data loggers, preventing terpene volatilization, phase separation, or butter drying during transit
