Also known as Grapefruit
A bright citrus peel smell with bitter, sharp and slightly aromatic character.
Its type, Source, means the smell is named after “a physical origin that can contribute a smell”; it is not an evidence source, such as a study or a book. The page for Grapefruit lists every smell recorded as coming from it.

QUESTIONS ABOUT GRAPEFRUIT PEEL
Grapefruit peel smells bright, sharp and bitter, with a citrus burst that feels sparkling at the front of the nose. Under the tang sits a slightly green, resinous aromatic note that sets it apart from lemon or orange. The scent is strong and quick, most vivid when the rind is twisted or scratched, and it fades into a drier, pithy bitterness.
It is met at breakfast when halving or peeling the fruit, in drink garnishes and in fruit salads. Many people also meet it in kitchens where citrus is zested for baking, dressings and marinades.
Typical settings: fresh fruit, breakfast, drink garnish.
SmellBook links it to one place page: see it in Connections.
One VERIFIED scientific claim from one published source is recorded for this entry: Volatiles of grapefruit peel oil. This claim says only what its source supports, in the scope shown with it.
The scientific study behind this evidence is chemistry or emission work, not a study of how the smell is perceived.
4 molecules are named in this claim; see the evidence for the role the claim gives them. Each molecule this claim names has only the role the claim states. Where a molecule is listed as a reported volatile, the claim does not say it shapes the smell.
Grapefruit Peel is centered on the rind rather than the sweeter fruit flesh.
Words that are easy to mix up: Is citrus a kind of fresh?
No historical source or heritage record is linked to this entry yet.
Answers marked EDITORIAL are written by SmellBook editors to describe the experience and add no scientific fact. Answers marked VERIFIED point to claims on published sources, checked against each source's own summary where one was available (each claim's page says how); what each claim supports is in its own text and scope.

Volatiles of grapefruit peel oil
Cold-pressed peel oil of redblush grapefruit from Kenya had limonene (91.1%), α-terpinene and α-pinene as the main compounds; nootkatone, α- and β-sinensal and methyl N-methylanthranilate were described as prominent.
One grapefruit form from one locality; it reports the oil's composition, not a sensory analysis.
How this was found: Chemical composition. Compounds were identified or measured, without any assessment of their odour. Source: primary study; chemistry work.

Each step is a relationship SmellBook editors recorded in the knowledge graph, named as it is published there. Paths are not ranked or personalised, and they do not mean the smells smell alike.
Each step is a molecule that a VERIFIED claim names for both smells, in whatever role the claims state. Sharing a molecule does not mean two smells smell alike.

Created 2026-09-22 · Updated 2026-10-06Dataset history In the SmellBook dataset since the first of three dataset releases of 2026-09-30; changed in the first of two dataset releases of 2026-10-05 (note).
Correction COR-0006 (2026-10-04): The note said the entry is centred on rind oils. No VERIFIED claim on the entry supports attributing the smell to rind oils, so the note now says the entry is centred on the rind rather than the sweeter fruit flesh. Corrections policyEVIDENCE MATTERS
