Cannabis tinctures are one of the products taking the new medical marijuana industry by storm. The ability to safely dose yourself with a reliable quantity of cannabinoids has been absent from the industry largely until now. A cannabis tincture is either an ethanol oral tincture or glycerin sublingual tincture. However, the main difference between the two being glycerin is absorbed via the mucous membrane and ethanol is ingested.
Recently I made a Cannabis tincture using pure kief. Decarboxylation is one of the most common questions regarding infused cannabis products. Decarboxylation is the process of THCA converting to THC. If cannabis is not decarboxylated, THCA is not converted and does not pass the blood brain barrier, resulting in no psychoactive high. Most methods will tell you to decarboxylate inside the oven, over a stovetop, double boil, all at or around 160 – 220 degrees fahrenheit. One of the most impressive features of Cannabis is this decarboxylation process happens naturally. This natural process is important because when plant matter or kief is heated past 80-90 degrees fahrenheit, terpenes and flavonoids are burned off. These compounds are responsible largely for the entourage effect and provide many of the medicinal benefits of cannabis.
Cannabis Tinctures – The Process
The process used to make our cannabis tinctures was incredibly simple, but understanding why it works is more important. I used 10 grams of 3 month old kief which sat in a stored container in a cool dark spot. By allowing the kief to sit 3 months, the decarboxylation process has taken place on it’s own because THCA naturally converts to THC over time. No need for heating the kief! I measured out 10 grams of kief and put it in a small mason jar. Then I measured out 10 ounces of 151 proof grain alcohol (Everclear) and poured it in with the kief. Shake every 10-15 minutes for 2-3 hours, then transfer to another clean mason jar using a coffee filter and funnel. Total process took time less than 4 hours from start to finish.
Our Cannabis tincture turned out great!
Why Use Kief?
The main advantages of using kief are;
- More Concentrated
- Easier to work with
- Chlorophyll contents greatly reduced
- No decarboxylation needed if kief stored for 3+ months
- Less material to filter
