Kümmel is a sweet, colourless liqueur flavoured predominantly with caraway seeds.
Syrupy and rounded on the palate, finishing on a warm, lingering caraway spice, with cumin and fennel trailing behind the dominant seed note.
Bartenders pour it stirred, either as a small sweet-and-spicy accent or as a base measure where its caraway aroma is meant to lead; the high sugar gives it body and a slick texture in the glass.
Hard to replace when its caraway aroma defines the drink; where it is a sweet accent, a caraway-forward spirit rebalanced with a simple syrup or other sweetener can approximate both the spice and the sugar load together.
Aquavit (akvavit)
Both take their principal flavour from caraway seed, but aquavit is an unsweetened distilled spirit whereas kümmel is a sweetened liqueur.
Distillers macerate caraway seeds in neutral spirit and redistil, sweetening the clear distillate afterward; cumin and fennel sit beneath the dominant caraway. The result is uncoloured, with sugar added after distillation rather than being intrinsic to its spice character.
Its high sugar can precipitate into crystals that settle at the bottom of the bottle over time; gentle warming and shaking redissolves them.
Kümmel was first distilled in the Netherlands in the late 17th century, later becoming strongly associated with the Baltic region — notably Latvia's Allasch — and with Germany.
