Elderflower liqueur is a sweetened, spirit-based liqueur whose defining flavour comes from the blossoms of the elder, most commonly Sambucus nigra.
Silky and sweet across the palate, finishing on a lingering floral note; the aroma is intensely blossomy, honeyed, and green.
Bartenders pour it as a floral sweetening modifier, stirred or shaken into a build in small measures to lend elderflower aroma and body; at larger doses it can carry a drink as a primary flavour. Because its whole purpose is that blossom note, it is not readily swapped out when the flavour is the point.
No substitute truly replaces it when the elderflower aroma is central, since that specific floral note cannot be reproduced from an unrelated sweet liqueur; as a minor accent, another floral liqueur of comparable sweetness can stand in, with sugar and strength rebalanced by a syrup or spirit.
Elderflower liqueur is an alcoholic, spirit-based product, whereas elderflower cordial and syrup are non-alcoholic sweetened flavourings. Both are made by steeping elder blossoms in sugar and share the same floral flavour, so they are often confused or used interchangeably in error.
The elderflower character is drawn out by macerating or infusing elder blossoms in an alcohol base to capture their aroma, after which the product is sweetened. Its flavour source is the flower of the elder (Sambucus nigra), the same species behind elderflower wines and cordials.
Its delicate, volatile aroma fades and can darken toward amber over time, especially in preservative-free products; keep sealed away from heat and light and use while fresh.
The modern commercial elderflower-liqueur category was effectively established in 2007 with a French product made from elderflowers hand-picked in the foothills of the French Alps, which prompted a wave of other elderflower liqueurs.
