What Are Terpenes? — Definition, Aroma Compounds & Cannabis Context (UK)

What Are Terpenes?

Terpenes are aromatic compounds found across many plants, including cannabis. In cannabis-related education and seed catalogue terminology, terpenes are commonly referenced when describing scent and flavour characteristics.

This page provides a neutral, reference-grade definition of terpenes as chemical compounds. It explains how the term is used in educational and catalogue contexts without offering instructions, advice, or guidance of any kind.

Terpenes — Clear Definition

Terpenes are naturally occurring aromatic compounds produced by a wide range of plants. They contribute to scent and flavour characteristics and are commonly discussed in botanical and chemical contexts.

In cannabis terminology, terpenes are referenced descriptively as part of a broader chemical profile rather than as predictive or outcome-based indicators.

Chemical & Botanical Context

Terpenes exist independently of cannabinoids and are found throughout the plant kingdom. In cannabis education, they are discussed alongside cannabinoids to help explain aroma-related language.

  • Cannabinoids — chemical compounds associated with cannabis.
  • Terpene profile — descriptive shorthand for reported dominant aromatic compounds.
  • Dominant terpene — catalogue language indicating the most prominent reported aroma compound.

For a structured overview of chemical terminology, see the Cannabinoids & Chemistry Knowledge Index.

How the Term Is Used in Seed Catalogues

In seed catalogues, terpene terminology is commonly used to describe scent and flavour notes using familiar descriptors.

These descriptions are sensory and descriptive only. They are not guarantees, instructions, or claims of effect.

Terpene language often appears alongside cannabinoid terminology such as THC and CBD, but refers to a separate class of compounds.

Terpenes are frequently discussed alongside the following reference concepts:

  • THC — a cannabinoid often referenced in catalogue banding.
  • CBD — a cannabinoid referenced in CBD-focused catalogue categories.
  • Cannabinoids — the broader compound family discussed in cannabis chemistry.

These terms are organised and cross-referenced within the Master Knowledge Index.
