Vanilla

Vanilla notes in wine and aged spirits come almost exclusively from oak barrels — specifically from compounds called 'oak lactones' that develop during cooperage and barrel toasting. American oak produces especially strong vanilla character. The vanilla note isn't from added vanilla beans; it's a natural by-product of how oak interacts with alcohol over time. The longer a spirit ages in fresh oak, the more vanilla character it develops. With 1,590 mentions across 18 categories on LivCheers, vanilla is one of the most universally recognised tasting notes — and one of the most common positive descriptors.

Vanilla character is recognisable as the sweet, creamy, slightly buttery aromatic familiar from vanilla extract. In wine, oaked Chardonnay (especially American oak-aged) is famously vanilla-driven. Bourbon — required by law to use new American oak — has pronounced vanilla notes. Rum aged in ex-Bourbon casks inherits vanilla character. Even brandy and Cognac, despite using French oak, develop vanilla notes (slightly more subtle) over extended aging. The vanilla character in a drink is one of the strongest indicators of meaningful oak influence.
