JUNIPER

Gin is, fundamentally, juniper rearranged. The spirit's name comes from the Dutch jeneverbes — juniper berry — by way of the 17th-century physician Franciscus Sylvius, who is widely credited with blending juniper into a malt-wine remedy he called genever. [source] The remedy long predates the spirit; Galen prescribed juniper to "cleanse the liver and kidneys," and plague doctors stuffed the beaks of their masks with it to ward off pestilence. [source] What began as medicine drifted, as good ideas do, into pleasure. The berries themselves still arrive the slow way — most of the world's commercial supply is wild-harvested by hand from the limestone uplands of North Macedonia and the hills behind Florence, knocked from the bush with a stick and caught in a sieve.

Juniper is the backbone of any classic gin — start here and build outward. A full sachet gives you a confident London Dry character: piney, resinous, structural. Drop to a half-sachet and you let the supporting cast lead — useful if you're building a citrus-forward summer gin or a floral contemporary style. Pair it with coriander and angelica for the classic trinity, or push it sideways with cardamom and a hit of pink grapefruit peel for something more aromatic.

Four terpenes do most of the work. Alpha-pinene carries the unmistakable fresh-pine top note — it's volatile, so it shows up first and fades fastest. Beta-myrcene brings a green, slightly hoppy body (the same compound that defines beer's bittering hops). Sabinene adds a sharp peppery edge, related to what you taste in cracked black pepper. Limonene rides underneath as a clean citrus lift. [source] Heat and time amplify the heavier, woodier compounds at the expense of the bright top notes — which is why a long, hot extraction will give you something resinous and deep, while a brief cool steep keeps it fresh and citric.
