Winterization

Winterization is a purification process in cannabis extraction that removes fats and waxes to produce a cleaner extract.

Also called / Category:

Also called "lipid removal," it falls under Extraction & Processing.

Key takeaways:

• Removes fats, waxes, and lipids from cannabis extracts.
• Involves dissolving extract in ethanol and freezing.
• Enhances the purity and quality of the final product.
• Commonly used in producing high-quality concentrates.

What it is / How it shows up:

You might see the term winterization on product labels or in extraction facility descriptions. It refers to a process where cannabis extracts are mixed with ethanol and then chilled. This chilling causes undesirable compounds like fats and waxes to solidify and separate from the desired cannabinoids and offset-4 transition-colors hover:underline" title="Learn more about Terpenes">terpenes. The result is a cleaner, more refined extract, often sought after for its purity and smoother taste. Winterization is a standard step in creating high-quality concentrates such as vape oils and shatter.

How it’s measured or identified:

• Visual clarity of the extract.
• Smoothness of the concentrate.
• Absence of cloudiness or haze.

Use in context:

• "This vape oil is winterized for a smoother experience."
• "Winterization ensures no waxy residue in shatter."
• "Our extraction process includes winterization for purity."

Safety & compliance in Canada:

• Only authorized facilities should perform winterization.
• All products must comply with Health Canada regulations.
• Labels should indicate if winterization was part of the process.
