Our process

From fresh frozen to your jar

Single-source resin, separated with ice water and finished without solvents, added terpenes, or fillers.
  1. 01

    Fresh frozen

    Whole plants are frozen promptly after harvest to preserve aromatic compounds and resin.

  2. 02

    Ice-water wash

    Cold water and ice gently separate the trichome heads from the plant material.

  3. 03

    Grade and select

    Each wash is separated by micron range, evaluated, and assigned to the tier it best represents.

  4. 04

    Finish the expression

    Melt stays minimally manipulated. Fresh Press is presented fresh, while Cold Cure and Jam develop distinct textures.

Storage

Protect the expression

Cold, sealed, and handled carefully—that is how the jar stays closest to the day it was finished.
01

Keep it cold

Store the sealed jar cold to preserve aroma, flavor, and consistency.

02

Warm before opening

Let the sealed jar reach room temperature before opening to help prevent condensation.

03

Reseal promptly

Close the jar after use and protect it from heat, direct light, and moisture.
