Gin
Juniper is not optional. Every other botanical is. One rule — and then limitless possibility. The spirit that went from Dutch medicine to London poverty to global cocktail culture.
Gin is an ethanol-based distilled spirit in which juniper berries (Juniperus communis) must be the predominant botanical flavour — this is the single defining regulatory requirement common to all gin categories under EU Regulation 2019/787. All other botanicals (coriander seed, angelica root, cassia bark, citrus peel, cardamom, and hundreds of others) are optional. The spirit is produced by flavouring neutral grain spirit (minimum 96% ABV in the EU) or, in some traditions (genever, pot distilled gins), lower-strength spirit, with botanicals — either by re-distillation with botanicals (distilled gin) or by cold-compounding (adding botanical extracts or essences without redistillation). The EU regulation defines four categories: Juniper-Flavoured Spirit Drinks (broad — includes cold compounding); Gin (juniper-predominant, no minimum ABV for production); London Gin (distilled only, no artificial flavourings, minimum 70% ABV from distillation, minimum 37.5% ABV bottled); and Distilled Gin (re-distilled with botanicals). The juniper flavour compound primarily responsible for gin's characteristic piney, resinous note is α-pinene and the monoterpene alcohol linalool — both major constituents of juniper berry essential oil.
Juniper — the one essential botanical
Juniper berries are the seed cones of Juniperus communis — not technically berries but fleshy, merged scales forming a berry-like structure. They contain the essential oil responsible for gin's defining character: approximately 50–80% α-pinene and β-pinene (piney, resinous, turpentine-like at high concentration, fresh pine forest at lower), plus linalool (floral/lavender), myrcene, limonene, and caryophyllene. All gins must have juniper as the predominant flavour — if coriander, citrus, or another botanical dominates, the product cannot legally be called gin under EU regulations.
Gin's historical origin: 17th-century Dutch medicine, where genever (from jenever, Dutch for juniper) was distilled by Franciscus Sylvius or his contemporaries. English soldiers encountered genever in the Dutch Lowlands during the 30 Years War and brought the taste for "Dutch courage" back to England. English gin evolved separately from Dutch genever — becoming lighter, more neutral-based — and became London's dominant spirit in the 18th-century Gin Craze (documented in the Gin Act 1751).
London Dry Gin
The regulatory definition of London Dry (EU 2019/787). Distillation-only flavouring, no post-distillation additions, juniper dominant. Tanqueray, Beefeater, Gordon's — the style that defined gin globally.
Contemporary & New World Gin
The craft gin revolution. Non-traditional botanicals, local ingredients, barrel ageing. When juniper takes a back seat — but still must be present. Hendrick's, Monkey 47, and the global new wave.
