How is CBG Oil Made?

Cannabigerol (CBG) is rapidly gaining traction as the new "it" cannabinoid molecule in the market. As the cannabis and hemp industries evolve, there's a growing interest in understanding the extraction process of CBG oil, especially given its potential therapeutic benefits. This article delves into the intricacies of CBG oil extraction, highlighting the methods and steps involved.

Key Takeaways

  • CBG, often referred to as the "Mother of all Cannabinoids," is the non-acidic form of cannabigerolic acid (CBGA), the precursor from which all other cannabinoids are developed.
  • The optimal time to harvest CBG is around 6 weeks into the 8-week flowering cycle of young cannabis plants.
  • CO2 and ethanol are the primary solvents used for CBG extraction, with CO2 being the preferred method due to its efficiency and quality of the end product.
  • The extraction process involves chilling, extraction, filtration, solvent evaporation, decarboxylation, distillation, and chromatography.

What is CBG Oil?

The CBG Extraction Process

Cannabigerolic acid - Wikipedia

  1. Harvesting: CBG is derived from young cannabis plants, which contain higher amounts of this cannabinoid than fully developed plants.
  2. Drying: The harvested plants are dried to eliminate excess moisture.
  3. Grinding: The dried plants are then ground into a fine powder.
  4. Extraction: The ground plant material undergoes solvent extraction using either CO2 or ethanol.
  5. Purification: The extracted oil is purified to remove impurities.
  6. Concentration: The purified oil is concentrated to enhance its potency.
  7. Testing: The final product undergoes testing to ensure it meets quality and safety standards.

CO2 vs. Ethanol Extraction

CO2 extraction is considered the most efficient method for extracting CBG oil, producing a high-quality product with minimal residual solvents. On the other hand, ethanol extraction can result in a lower-quality product with more residual solvents.

Challenges in CBG Production

Producing CBG is currently costly due to its scarcity in cannabis strains and the precise timing required for harvesting. However, breeders are working on developing high-CBG strains to make the extraction process more efficient and affordable.


As the cannabis industry continues to evolve, CBG oil stands out as a promising product with immense potential. Its extraction process, while intricate, ensures the production of a high-quality, therapeutic compound that's set to revolutionize the wellness market.
