Definition - What does Terpenes mean?
Terpenes include a large and diverse category of compounds that are produced by many plants and some animals.
In the wine industry, only a handful of grape varieties release aromas from terpenes. One example is the Muscat grape. For some wines and even beer, this is a desired trait. An example would be the terpenes released from hops in beer-making.
