The Interpening Book: Interpening explains the methodology of interpening and how to utilize interpening tools. It is designed to teach you how to evaluate cannabis by following a deductive process that encompasses both technical sciences and sensory observations and will enable you to identify the quality and psychotropic effects of cannabis variety types. Based on knowledgeable cannabis evaluations, an Interpener can describe the overall quality of cannabis flower and make recommendations for desired effects. Ultimately, this book equips you with knowledge that will enhance your professional, medicinal, or recreational experience. We strongly recommend this book as a companion tool while completing an online or live interpening course through Trichome Institute.

Interpening pronounced “in-terp-en-ing” is the science of evaluating cannabis flower to determine quality, variety type designation, and psychotropic effects, through physical and aromatic inspection. Interpening is based on a combination of science and theory, yet it is also an art and requires significant experience. An interpener can be thought of as a cannabis sommelier. In fact, interpening was inspired by the model of sommelier certification, including education, training, and practice to develop such a recognized expertise.

Interpening is important at a time when millions of people are purchasing cannabis for medicinal or recreational purposes without quality certification or assurance of potential psychotropic effects. The psychotropic effects of cannabis vary from plant to plant and even within the same strain name, which is why strain names are so misleading.

The methods of interpening are used to identify cannabis variety type and better understand the potential psychotropic effects of each flower. This is done by visually evaluating the physical characteristics of the flower and by interpreting the aromatics, or terpenes which are the evaporating molecular hydrocarbon chains that produce the aromas of plants.

In legal states, many lab testing requirements for cannabis do not include mandatory terpene testing to provide insight to the possible psychotropic effects, and even those that do are only a guide, as the quality of the flower can change drastically between testing and consumption. While it is mandatory to test for various cannabinoids like THC, the percentage of THC in flower does not actually determine potency, which is why interpening the flower’s terpene profile is so important. Through interpening, you will have the tools to evaluate cannabis for its potency and psychotropic effects, regardless of strain name, lab test results, or presumed subspecies. Interpening also enables you to evaluate the total quality of the flower and determine whether it is an unacceptable, acceptable, or high-quality product, and ultimately safe to consume.
