Cannabis extractions have significantly evolved in recent years, offering more efficient and safer methods to obtain high-quality concentrates. These extracts, rich in cannabinoids and terpenes, provide a more potent and cleaner experience compared to traditional flower. In this article, we will explore solvent-based and solventless extraction methods, including recent innovations such as Live Resin and Rosin.
Solvent-Based Extractions
Solvent-based extraction methods use chemical substances to separate cannabinoids and terpenes from plant material. The most commonly used solvents include butane, propane, CO2, and ethanol.
1. Live Resin
Live Resin is one of the most valued extracts in the industry due to its high terpene content and fresh aromatic profile. It is obtained from freshly harvested cannabis flowers that are immediately frozen, preserving the freshness and quality of volatile compounds.
Process:
- The plant material is frozen at extremely low temperatures.
- Extraction is performed using butane or propane in controlled conditions.
- The solvent is purged at low temperatures to maintain terpene integrity.
2. BHO (Butane Hash Oil)
BHO is a widely used method that produces extracts such as shatter, wax, and budder. It is known for its high potency and purity.
Process:
- Liquid butane is passed through the plant material to extract cannabinoids.
- The butane is evaporated using controlled heat in a vacuum environment.
- The final product is refined to remove any residual solvent.
3. Supercritical CO2 Extraction
This method is safe and efficient as it uses supercritical carbon dioxide to extract cannabinoids without leaving toxic residues.
Process:
- CO2 is subjected to high pressure and temperature to reach a supercritical state.
- It is passed through the plant material, extracting active compounds.
- Cannabinoids and terpenes are separated in collection chambers.
Solventless Extractions
Solventless methods use heat, pressure, or mechanical friction to extract cannabinoids without the need for chemicals. These options are more natural and consumer-safe.
1. Rosin
Rosin is obtained by applying heat and pressure to flower or hash, resulting in a pure solventless concentrate.
Process:
- The flower or hash is placed in parchment paper.
- Pressure is applied using a specialized heat press.
- The resulting extract is collected, ready for immediate consumption.
2. Hash Frozen Rosin
Hash Frozen Rosin is an advanced solventless extraction technique that involves freezing hash before pressing it into rosin. This method enhances terpene preservation and yields a cleaner, more flavorful product.
Process:
- High-quality hash is frozen to preserve terpenes and prevent oxidation.
- The frozen hash is pressed at controlled temperatures and pressure.
- The final product is collected, offering a potent and aromatic extract.
3. Dry Sift and Traditional Hash
This method consists of mechanically separating trichomes through dry sifting or ice water extraction.
Process:
- The flower is rubbed over screens of different microns to collect trichomes.
- It can be pressed to create traditional hash or Bubble Hash.
- Depending on refinement, a superior quality product such as Full Melt Hash can be obtained.
Best and Natural Consumption Methods
For those seeking the most natural and efficient way to consume cannabis extracts, the following methods are recommended:
- Dabbing Rosin or Hash Frozen Rosin: Using a low-temperature dab rig ensures maximum terpene preservation and flavor.
- Vaporization: Devices like concentrate vaporizers provide a smooth and controlled experience without combustion by products.
- Infused Edibles: Rosin and solventless extracts can be incorporated into foods for a longer-lasting effect without inhalation risks.
- Traditional Hash Consumption: Smoking hash in a pipe or mixing it with flower is a classic, natural method.
Trends and Future of Extractions
Cannabis extractions are focused on improving efficiency and purity in the final product. New hybrid methods combining solvent-based and solventless technologies are being developed to maximize cannabinoid and terpene profiles.
Additionally, regulations and quality standards continue to evolve, demanding safer and more transparent processes. With the increasing demand for premium products, innovations in extraction techniques will continue to shape the industry’s future.
Cannabis concentrates have revolutionized how consumers experience cannabinoids and terpenes. Both solvent-based and solventless methods have their advantages, and the choice depends on personal preferences and quality standards. With constant technological advancements, the industry continues to offer purer, more potent, and safer products.
