QUESTIONS ABOUT YOGURT
Yogurt smells cool, creamy and tangy, with a light sourness that sits on top of a soft dairy base. Plain yogurt is clean and fresh rather than strong, close to sour cream or buttermilk, and the sharp edge is easiest to notice when a new pot is first opened. Thicker styles feel rounder and richer, while added fruit or honey can sweeten the odour considerably.
It is met at breakfast, beside fruit bowls and granola, in refrigerated aisles and in kitchens where sauces and dips are made. Many people also meet it in marinades, cold soups and desserts served in warm weather.
Typical settings: breakfast, refrigerated food, fruit bowl.

Compounds that shape yogurt aroma
A review reports more than 100 volatiles in plain yogurt and finds that, besides lactic acid, acetaldehyde, diacetyl, acetoin, acetone and 2-butanone contribute most to its typical aroma and flavour.
Plain yogurt; extended storage produces off-flavours from lipid oxidation.
How this was found: Broad account. A broad statement about how an aroma forms, how it is studied or what a term means, rather than one measurement. Source: review of earlier studies. Studied: plain yogurt flavour research reviewed, instrumental and sensory.

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.
