“50 Shades of Hash”
Blue River Learning Lab 🔬
A traditional harvest includes removing all fan leaves while cutting down the plant into sections that are then hung upside down for 5-14 days in a control environment. During the drying process terpenes, the aromatic compounds that give cannabis its unique smell and flavor are quite volatile, begin to evaporate at room temperature. A low temp prolonged “cure” will preserve terpenes better while allowing for enzymes and aerobic bacteria to break down any remaining minerals and undesirable sugars produced by the decomposition of chlorophyll to during the drying process. The presence of these sugars and remaining minerals is what causes the harsh, throat-burning sensation you get from smoking improperly cured cannabis. When a plant is still alive the cannabis buds and resin are rich in monoterpenes. As the product ages, the monoterpene content converts to a higher percentage of of sesquiterpenoids, as often occurs in extracts.
The old school art of Hashish making utilizes dry cured buds to allow for separation of glandular trichome heads from the head stalks attached to the surface of the buds in a mechanical process using controlled environments, vibration, sieves, and static. Hashish is made by pressing those heads together into balls or blocks. Dry Sift is the separation of glandular trichomes without pressing them together, but rather isolating specific resin heads that can be sold as is or further refined mechanically into Dry Sift Rosin.
Today, Ice Hash, (commonly referred to as ice water hash, bubble hash, or wet sift) is a cannabis extract formed by removing the glandular trichome heads from whole plant cannabis buds in the presence of ice water. Ice hash is a modern form of hash making, and just like traditional hash, can be crafted by hand or mechanically. Today, Ice Hash is made from freshly frozen whole plant (FFWP) cannabis buds only or dry cannabis buds with classifications based on the “head” size and the rating of the “melt”. Bubble Hash, “Full Melt”, made from FFWP is a fresh product that needs to be cared for with temperature control for consumers. “Live” Rosin is made mechanically from FFWP Ice Hash.
Hashish is not considered an “Solventless Hash Oil” or “Rosin” until the heads are actually squished / pressed to remove the compounds from within the outer walls of the glandular trichome heads themselves. As seen in the top middle image, many types of glandular and non-glandular trichomes develop at different rates based on the length of flowering time built into the dna of the strain. Trichome heads make up the largest concentration of the plants cannabinoids, terpenes, and flavanoids. Collecting trichomes is as much science as it is an artesian skill. The middle left and middle image is a full spectrum “solventless hash oil” made from all the trichome heads as seen in the top right image. A full spectrum dry sift rosin ”SHO” has a robust flavor with a full range effect and will have variation in color based on the resin profile. The middle right image is a Live Rosin made from harvesting trichomes from fresh frozen buds and selecting a smaller range of head sizes (70u-120u) to be pressed into a rosin. Live Rosin has a washed out white look, or can be a clear yellow oil, but a ultra refined smooth floral like plant flavor profile. Our A (bottom left), Flan (bottom middle), Jelly Sauce (bottom right) are all mechanically separated out from either types of Rosin. All these solventless extracts are valued based on the amount of work it takes and the steps it takes to achieve these end results.
