Principle
Lactones are cyclic esters, while vanillin is an aromatic aldehyde with phenolic and methoxy functionality; neither is a wood sugar.
Evidence And Locators
Clayden printed p. 532 for lactones and p. 409 for vanillin; chapter 2 functional groups.
Application
Use separate categories for carbohydrates, lignin-derived aldehydes, phenols and lactones in Academy explanations. Chemical class should not be inferred from a sweet aroma descriptor.
Boundary
This classification does not quantify extraction, concentration, sensory contribution or a blend's sweetness.
