Where it comes from
Biosynthetic pathway: Fatty acid derivatives — enzymes cut fat chains into fragments you can smell.
Why it sits where it does
A saturated eight-carbon alcohol with no double bond, so it is more stable and less prone to oxidation than its relative 1-octen-3-ol.
Where else you meet it
Mushrooms of all kinds, leaf litter, and some wines with an earthy note.
