§ 01PROCESS · FLOWER → JAR
NOTHING ENTERS A JAR THAT WASN'T WASHED IN-HOUSE.
STEP · 01

FRESH FLOWER

Whole-plant material is harvested at peak terpene expression and snap-frozen within the hour. No drying. No curing. Trichomes locked at full integrity.

STEP · 02

ICE WASH

Frozen flower agitates in an ice-water bath. Resin heads break away from plant matter and sink — collected through stacked stainless micron screens (159μ → 25μ).

STEP · 03

FREEZE-DRY

Wet bubble hash freeze-dries under vacuum. Removes residual moisture without applied heat — preserves volatile terpenes that low-temp pressing can't recover later.

STEP · 04

COLD PRESS

Hash presses at 180–200°F between unbleached parchment. The lowest viable temperature that yields a full-melt return. No solvents. No additives. No filtration.

Mandarin Z fresh press — whole flower straight between the plates, jarred warm off the parchment the same week. No wash, no cold cure. Mandarin peel and grapefruit come through loudest in the first two weeks, before the window closes. Deep gold sap that stays wet in the jar.

Our flagship rosin pressed from one of the strains that defined IE. Mackinaw OG hash carries the classic peach-and-diesel signature of the parent flower into a clear amber budder that melts on contact. Long, slow exhales of stone fruit and gas. Body-heavy and meditative.

Limeheadz washed live and pressed cool to protect the pinene. Lime rind and sour candy land first, with the flower's gassy diesel sitting underneath. It cold-cures to a chunky, lacquered pale-gold budder that holds an edge on the tool instead of running. Pressed at 185°F — the low end of our band, because this profile is the first thing heat takes.

Rainbow Belts 13 is our loudest wash of the season and it cures the driest. Gummy candy and sour citrus come off the jar before the lid clears; the creamy gas shows up on the exhale. This one nucleates into a pale straw sugar rather than a budder — granular, sandy at the edges, scooping without stringing. Pressed at 185°F to protect the linalool.

GAK Rainbows pressed live yields one of the most expressive terpene profiles we've ever cold-bottled. Garlic-funk gas hits first; sour fruit candy follows on the exhale. Glossy budder consistency, jar-stable for months. A connoisseur jar.

Original Z built our reputation. Pressed live, it returns a tropical-citrus opening that transitions into a creamy, candy-sweet finish. Terpene-loud, cleanly washed, balanced enough to chase across a long session without losing the thread.

Zkittlez washed live and pressed at 190°F, then cold-cured until it set. The classic candy profile survives intact: grape and berry up front, tropical fruit underneath, no vegetal edge anywhere in it. It comes out pale blond and clumped, closer to a wet crumb than a smooth budder, and it breaks apart clean on the tool.
