QUESTIONS ABOUT BUTTER
Rich, creamy and gently warm, butter smells soft and rounded with a mild dairy sweetness. Cold from the fridge it is faint and clean; softened or melted it opens into a fuller, almost nutty warmth. When it browns in a pan the smell deepens towards toasted and caramel-like. It is easily confused with cream or with buttery baking, though plain butter is quieter and smoother.
It fills the kitchen during baking, rises from toast at breakfast and from a pan when butter melts before cooking. Bakeries and pastry counters carry a warm, buttery air through much of the day.
Typical settings: baking, toast, kitchen.
SmellBook links it to one place page: see it in Connections.
One VERIFIED scientific claim from one published source is recorded for this entry: Key odorants of butter. This claim says only what its source supports, in the scope shown with it.
3 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; one molecule is not the whole smell.
Butter changes significantly when cold, melted or browned; this is a broad kitchen-facing profile.
Words that are easy to mix up: Why is creamy not just sweet? and Is every warm smell spicy?

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.
Scientific evidence · 1 claim
A review of aroma studies reports that sweet cream butter is characterised by lactones and sulfur compounds, while the key odorants of sour cream butter are diacetyl, butanoic acid and δ-decalactone, formed mainly by lactic acid bacteria.
Key odorants differ between sweet cream, sour cream and heated butter and butter oil.
How this was found: Odour analysis with human assessors. People smelled the separated compounds or the material itself (for example gas chromatography–olfactometry, dilution analysis, recombination or a sensory panel). Source: review of earlier studies; sensory or perception work.

PATHS FROM HERE
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.
