ANISEED

Aniseed travelled with every Mediterranean civilisation. The ancient Egyptians used it for embalming and digestion; the Greeks and Romans crystallised it into a digestive sweet eaten after rich meals — a custom that survives today in Italian anice candy. In the 8th century, Charlemagne mandated that aniseed be planted in his imperial gardens across the Carolingian Empire, which is largely how the spice took root across central Europe. [source] By the Middle Ages it was being distilled into spirits across the Mediterranean — the parent line of every aniseed liquor from Provençal pastis to Greek ouzo, Turkish raki, Lebanese arak and Italian sambuca. In gin it functions both as a flavour and as a digestive cue: aniseed signals "after dinner" to the palate even before you've tasted the drink.

Aniseed is powerful — a full sachet pushes a gin firmly into pastis-adjacent territory and will dominate any subtle co-botanicals. A quarter to half sachet does its best work as a back-palate sweetener, layering depth without taking over. It pairs naturally with fennel seed and star anise (all three share trans-anethole) for a Mediterranean digestive profile, or with liquorice and orange peel for something more confident and Italian-leaning.

Trans-anethole makes up around 72% of aniseed's essential oil — the highest concentration of any common spice, which is why aniseed reads as the purest expression of the "liquorice" note. [source] Limonene layers a citrus brightness on top, and anisole contributes a slightly nutty, almost coffee-like depth that gives quality aniseed its complexity over plain artificial anise flavour. Trans-anethole is fat-soluble and only partially alcohol-soluble — which is why aniseed-based spirits go cloudy when you add water (the louche effect). The compound survives heat well, so warm extractions develop the sweet-liquorice body without losing the bright top.
