Hemp-Derived Terpene-Infused Beer:
HemptasiaBy: Erin Babcock Co-Owner of Primo Gardens Inc – Short North, Columbus, OH UMB Medical Cannabis Science & Therapeutics Student Terpenes are small, aromatic compounds that play a role in the essence of many plants, including the cannabis plant. In addition to unique smells and tastes, terpenes also possess unique functional properties that can have potentially therapeutic effects. Just like CBD and other molecules, terpenes can be extracted from Hemp too. The process of extracting terpenes is congruent with the process of extracting CBD. A wiped film distiller is used to collect cannabinoids, including CBD, and filter out terpenes and other solvents. This starts by imputing hemp crude oil which is extracted from the hemp plants. As the distillation occurs, CBD molecules collect in the internal condenser, while terpenes and solvents build up in a flask below the cold trap. This is how the terpenes are extracted, but they are then isolated from the solvents using column chromatography.

Primo Gardens Inc., a CBD manufacturing company, partnered with Third Eye Brewing Co., a microbrewery in Cincinnati, to develop a hemp-derived terpene-infused brew. Primo Gardens isolated the terpenes, using the techniques described, from a strain called Cherry Blossom, with the dominating terpenes being Myrcene, B-Caryophyllene and Humulene.
- Myrcene is one of the most abundant terpenes in cannabis and at higher levels, it creates a sedating effect, helping the body relax. While at lower levels, it can help to energize. (Sommano et al, 2020)
- B-Caryophyllene is known for its calming and stress-reducing properties. It also directly interacts with and activates the CB2 receptor, which is a component of the Endocannabinoid System which helps the body maintain homeostasis. (Sharma, 2016)
- Humulene is commonly found in both cannabis and hops, which are used to make beer. Like the other terpenes, it also exhibited relaxing effects. Humulene is also studied for its promising potential for anti-inflammatory actions. (Rogerio, 2009)
