KAPN FIELD GUIDE / AROMA & FLAVOUR
Farnesene
Farnesene names a family of sesquiterpene isomers. The apple evidence concerns (E,E)-α-farnesene specifically; other farnesene isomers are distinct compounds.
Where it occurs naturally
(E,E)-α-farnesene is an apple-fruit volatile synthesized predominantly in epidermal and hypodermal fruit layers and associated with ripe apple. Sources: Biochemistry of Apple Aroma: A Review
Aroma & flavour
(E,E)-α-farnesene is associated with ripe apple; one apple volatile-profiling paper also reports it among green-grassy volatiles. These descriptions concern apple volatile profiles, not a validated odor profile for isolated farnesene.

What has research actually studied?
Apple-volatile research describes α-farnesene biosynthesis and its association with superficial scald in stored apple peel. This is plant chemistry, not an effect study. No human, animal, or cannabis-product effect study was identified. Sources: Biochemistry of Apple Aroma: A Review
What the evidence does not show
Apple-fruit biosynthesis, aroma mixtures and storage disorders do not establish an effect in people. Evidence about α-farnesene does not establish properties of other isomers.
What does its presence in cannabis mean?
A cannabis-product listing cannot predict an orchard-fruit aroma or an effect. Terpene presence alone does not give the product’s concentration or complete volatile profile.
