Interpening is a combination of the words “interpreting” and “terpenes.”

Interpening was developed by Max Montrose in 2008. Since it’s inception, Trichome Institute has hosted dozens of workshops teaching individuals from all around the world, including celebrities, industry veterans, and novices who are simply interested in learning more about cannabis.

Sommeliers, cicerones, cheesemongers, and coffee cuppers have perfected their palates to evaluate, grade, certify, and relay their expertise to the world. Trichome Institute is the first to bring the level of perfection and expertise to the world of cannabis.

For four solid hours, everyone from managers of dispensaries to growers, budtenders and owners learns how to pick up a plant and detect everything they need to know about the cannabis from its smell, bud structure and leaves. If you pay attention and pass a test at the end of the class, you’ll win official certification as a weed sommelier.
