Terpinolene plays a key role in defining the taste and smell of many cannabis strains, including the immensely popular, terpinolene-dominant strains Dutch Treat, XJ-13, and Golden Pineapple. It’s also likely to affect a strain’s therapeutic and experiential qualities. Terpinolene’s aroma is more multidimensional than some other cannabis terpenes. It carries an array of smells you might find in cannabis: It’s piney, floral, herbaceous, and even a little citrusy. One word that comes up often when describing terpinolene’s taste and smell: fresh.
