YIELD: 2 TO 3 TABLESPOONS
A cannabis concentrate is an oily liquid composed almost entirely of the cannabinoid and terpene-rich resins made by the cannabis plant. Concentrates are usually made by soaking cannabis bud and/or sugar leaves in a solvent to extract the cannabinoids and terpenes, then driving off the solvent; what remains is almost pure resin. Because I value safety, I use food grade ethanol as the solvent to make my concentrates and use an herbal extractor to safely evaporate and recover the ethanol for future use. This dark green/black concentrate is loaded with cannabinoids to use in topicals that are safe for the skin. High in quality, this concentrate is also known as cannabis oil, consumed in tiny quantities for a powerful impact. To make it, I use a Source Turbo extractor, which is a tabletop device that helps to preserve the integrity of the concentrate by keeping the temperature at or below 100 degrees F, while evaporating and recovering ethanol with vacuum pressures. It is important to note that to achieve the best results, use only 100 percent pure food-grade ethanol. If you are unable to find food-grade ethanol, you may substitute a high-proof neutral spirit such as Everclear. Do NOT use isopropyl alcohol or denatured alcohol for this recipe; those are not food-grade products.
1 pint food-grade 100% (200 proof) ethanol
60 grams dried decarboxylated cannabis bud, chopped
Place the cannabis in a wide-mouth glass container with a lid. Pour the ethanol over the cannabis and close the container. Allow the cannabis/ ethanol mixture to rest for an hour. Gently agitate the container every 10 minutes to facilitate the movement of the cannabinoids into the ethanol.
Using several layers of cheesecloth or a nutmilk bag, strain the cannabis from the liquid into a glass measuring cup big enough to hold the liquid. Strain the liquid again through a coffee filter for optimal clarity of the final concentrate.
Follow the extractor manufacturer’s instructions to evaporate off the ethanol, reserving it for a future extraction. Store airtight in a cool, dark spot. It will remain potent for a year or longer.
