Hemp Extraction & Processing Methods

The way cannabinoids are extracted from hemp plays a big role in the purity, potency, and flavor of the final product. Each method has unique advantages depending on whether you want maximum natural compounds, solvent-free extracts, or large-scale efficiency.

Live Resin

Live resin is made from fresh hemp plants that are flash-frozen immediately after harvest. This preserves delicate terpenes (aromatic compounds) and cannabinoids that may be lost during drying. Products made with live resin are often more flavorful, aromatic, and full-spectrum, giving users the closest experience to the raw plant.

Rosin

Rosin is produced through a solventless method, using only heat and pressure to squeeze cannabinoids and terpenes from hemp flower or hash. Because it avoids solvents or chemicals, rosin is considered one of the cleanest and most natural extractions, prized for purity and safety.

CO₂ Extraction

CO₂ extraction uses pressurized carbon dioxide to pull cannabinoids and terpenes from hemp. This method is highly precise and produces pure, consistent oils with customizable cannabinoid ratios. It’s widely used in the hemp industry and is considered safe and environmentally friendly.

Ethanol Extraction

This method uses food-grade ethanol (alcohol) to extract cannabinoids at scale. Ethanol is highly efficient, making it popular for producing large batches of full-spectrum extracts. However, additional filtering is sometimes required to remove chlorophyll and unwanted plant compounds.

Hydrocarbon Extraction (Butane/Propane)

Hydrocarbon solvents like butane or propane can be used to create highly potent concentrates. This method is great for preserving terpenes and producing flavor-rich extracts, but it requires careful handling and professional equipment to ensure all solvents are properly purged.

Distillate Processing

Distillation is a refinement process where cannabinoids are separated and concentrated into nearly pure forms. Hemp distillates can reach over 90% cannabinoid content, making them ideal for potent vapes, edibles, and tinctures. While highly effective, distillates often lack the natural terpenes found in less processed extracts.

Isolate Production

An isolate is the purest form of a single cannabinoid (like CBD isolate). All other plant compounds, including terpenes, are removed. Isolates are tasteless and versatile, perfect for people who want just one cannabinoid without THC or extras.

Mechanical Separation

A simple, solvent-free method where trichomes are physically separated from hemp using sifters, grinders, or tumblers. The result is kief or dry sift, which can be pressed into hash. It’s natural but not as potent or pure as other methods.

Steam Distillation

An older technique where steam passes through the plant material, carrying cannabinoids and terpenes with it. After condensation, oils are separated from the water. It’s less precise than CO₂ extraction and can degrade some cannabinoids with heat, but still used for essential oils and some hemp extracts.

Lipid Infusion (Oil Infusion)

In this method, hemp is infused directly into carrier oils like olive oil, coconut oil, or MCT oil. It’s one of the oldest and simplest forms of extraction, safe for home use, but has a shorter shelf life and lower potency compared to professional extractions.

Chromatography

A refinement method used to separate specific cannabinoids from a full-spectrum extract. It’s often used to remove THC to make broad-spectrum CBD products. This technique allows precise customization but is more complex and costly.

Nanoemulsification

A modern technique that breaks cannabinoids into nano-sized particles so they can mix into water-based products (like beverages). This increases bioavailability, meaning the body absorbs cannabinoids faster and more efficiently.
