Anethole Expression

Anethole expression refers to the genetic capacity of cannabis plants to produce anethole, a phenolic compound commonly associated with licorice, fennel, and anise-like aromatic notes. This terpene-adjacent chemistry appears in select cultivars, particularly those with heritage lines tracing through certain Landrace and Old World Heirloom families. Anethole itself is not a major terpene in cannabis but emerges as a minor volatile or secondary metabolite in specific genetic backgrounds. Breeders working in heritage and aromatic preservation have documented anethole presence across Mediterranean-influenced lineages and some Sativa-dominant stock. Understanding anethole expression requires attention to growing conditions, harvest timing, and full chemical profiling rather than aroma alone, as other compounds often co-occur.

Breeders pursuing complex flavor profiles and aromatic diversity track anethole expression as a minor but distinctive chemical marker. Selection for this trait typically occurs within broader lineage work focused on preserving heirloom character and terpene complexity rather than as a primary breeding target.
