What Is Cannabis Distillate?
Cannabis distillate is a purified cannabis extract that isolates specific cannabinoids like THC or CBD through fractional distillation. These products can reach purities as high as 99%, making them among the most potent cannabis concentrates available.
Unlike live resin or hash oil, distillates are stripped of almost all terpenes and flavonoids during distillation. However, you can add these back in later to customize flavor and therapeutic effects.

How Does Cannabis Distillation Work?
Cannabis distillation uses fractional distillation under vacuum pressure, a technique borrowed from chemical refining, to separate cannabinoids based on their boiling points.
Key Boiling Points of Cannabinoids:
| Cannabinoid | Approximate Boiling Point (°C) |
| THC | ~157 |
| CBD | 160–180 |
| CBN | ~185 |
By carefully controlling vacuum pressure and temperature, each cannabinoid vaporizes and condenses separately, leaving behind unwanted compounds and impurities.
How to Prepare Cannabis for Distillation (Drying, Curing, and Testing)
Step 1: Choosing the Right Raw Material
Start with clean, potent cannabis. Select biomass with high cannabinoid and terpene content, free from mold, pesticides, and heavy metals.
Step 2: Drying & Curing
- Harvest cannabis at peak maturity to capture full cannabinoid and terpene profiles.
- Dry the plant material to reduce moisture and prevent microbial growth.
- Cure dried buds properly to break down sugars, enhancing flavor and potency.
- Trim buds and test potency and contaminants in a certified lab.
Common Initial Extraction Methods
Before distillation, cannabinoids must be extracted into a crude oil. Here are the most popular extraction techniques:
- CO2 Extraction: Clean, safe, and uses supercritical CO2 as a solvent.
- Ethanol Extraction: Efficient and scalable, though it may extract chlorophyll, requiring further cleanup.
- Hydrocarbon Extraction: Uses butane or propane for high yields, but involves flammability risks and requires careful handling.
Expected Yields:
Yields vary by method and quality of starting material, typically ranging from 10–25%.
Step-by-Step Guide: Producing Cannabis Distillate at Home or in a Lab
Step 1: Initial Extraction
- Purpose: Separate cannabinoids and terpenes from the plant material to create crude oil.
- Methods: Use a CO₂ extractor, ethanol, or hydrocarbon-based system.
- Note: Always start with contaminant-free, lab-tested biomass to ensure product safety and quality.
Step 2: Winterization
Dissolve the crude oil in ethanol and chill it to –20°C or lower for 24–48 hours. This crystallizes unwanted fats, waxes, and lipids.
After chilling, filter out the solidified impurities.
- Why it matters: Winterization enhances clarity, stability, and overall purity of the extract.
Step 3: Decarboxylation
Heat the winterized oil at controlled temperatures to activate cannabinoids (e.g., THCA → THC, CBDA → CBD).
- Purpose: Converts inactive acidic cannabinoids into their active, bioavailable forms.
- Essential for: Producing psychoactive effects and ensuring potency in final products.
Step 4: Distillation
Utilize short path or wiped film distillation under vacuum conditions to separate and purify cannabinoids.
By targeting specific boiling points, you vaporize cannabinoids and condense them into a highly potent, clear distillate.
- Outcome: A refined oil free of chlorophyll, terpenes, solvents, and other residual compounds.
Step 5: Cannabinoid Isolation (Optional)
To isolate pure THC, CBD, or minor cannabinoids, apply chromatography or perform multiple rounds of distillation.
Use case: Precision formulations, pharmaceutical applications, or high-purity product lines.
