Gin has one rule that matters above all — it has to taste of juniper — and a hundred marketing terms layered on top. This glossary cuts through them. Every entry is a plain-English definition first; where it helps, we add how the term shows up in the glass, the rule behind it, and the myth it's usually wrapped in.
A
ABV / Proof
Alcohol by volume (and, in the US, proof = twice ABV). Most gin sits at 40–47% ABV; a higher strength carries botanical oils better and stands up in cocktails.
It's why <a href="/articles/tanqueray-london-dry-gin-review">Tanqueray</a> at 47.3% holds its own against tonic where softer, lower-proof gins fade.
B
Botanical Basket
The perforated chamber inside a still that holds botanicals for vapor infusion, letting alcohol vapour draw out their aromatics without direct steeping.
Botanicals
The herbs, spices, roots, fruits, and seeds that flavour gin. Juniper is mandatory; the rest — coriander, angelica, citrus, orris, and dozens more — make up a distiller's signature recipe.
Botanical count isn't quality, but it shapes character. <a href="/articles/the-botanist-islay-dry-gin-review">The Botanist</a> layers 22 hand-foraged Islay botanicals for real complexity; <a href="/articles/tanqueray-london-dry-gin-review">Tanqueray</a> makes a benchmark with just four.
C
Cold Compounding / Post-Distillation Infusion
Adding flavour after distillation rather than distilling with botanicals. At the cheap end it's 'bathtub' compound gin; done well it's a deliberate technique for delicate flavours that distillation would destroy.
It isn't always a shortcut: <a href="/articles/hendricks-gin-review">Hendrick's</a> infuses cucumber and rose <em>after</em> distillation precisely because those delicate notes wouldn't survive the still.
Column Still
A continuous still used to make the neutral base spirit for gin, and sometimes the gin itself. Produces a lighter, cleaner, higher-throughput spirit than a pot still.
Compound Gin (Bathtub)
Gin made by simply mixing botanicals or flavourings into neutral spirit with no redistillation. The lowest-effort category — occasionally characterful, usually cheap.
Most quality gin is distilled, not compounded. If a bottle is suspiciously cheap and vague about its method, compounding is often why.
Copper Pot Still
The traditional batch still used for small-batch gin distillation. Prized for the rounded, characterful spirit it produces, versus lighter continuous-column distillation.
<a href="/articles/sipsmith-london-dry-gin-review">Sipsmith</a> famously revived copper-pot gin distilling in London — its still, 'Prudence', is the heart of a classic London Dry.
D
Distilled Gin
Gin made by redistilling neutral spirit with botanicals. Unlike London Dry, it may have flavouring or colour added <em>after</em> distillation — the category that allows post-distillation infusions.
F
Foraged / Terroir Botanicals
Botanicals gathered from a specific place, giving a gin a genuine sense of origin. A hallmark of the craft movement.
<a href="/articles/the-botanist-islay-dry-gin-review">The Botanist</a> hand-forages 22 botanicals on Islay — heather, chamomile, gorse — for a gin that genuinely tastes of where it's from.
G
Genever (Jenever)
/juh-NAY-ver/The Dutch and Belgian malt-wine spirit that gin evolved from. Richer, maltier, and more whisky-like than modern gin — the original 'Dutch courage'.
Genever is gin's ancestor. If you want to taste where the whole category came from, this malty, characterful spirit is the missing link.
J
Juniper
The berry-like cone of <em>Juniperus communis</em> and the defining, legally required botanical of gin. It gives that piney, resinous, fresh character. No juniper, no gin.
By law (EU and US), gin's predominant flavour must be juniper. A spirit that doesn't taste of juniper legally isn't gin, however many trendy botanicals it carries.
If you can barely taste juniper, you're drinking flavoured vodka in gin's clothing. Juniper leading the profile is the whole point of the category.
L
London Dry Gin
The classic, driest, most juniper-forward style. All botanicals must be added during distillation, nothing (except a little water) may be added afterward, and no colouring or sweetening is allowed.
London Dry is a legally defined production method, not a place — it can be made anywhere. It requires all-natural botanicals distilled together, no additives after distillation, and minimal added sweetness.
'London Dry' says nothing about geography. It's a method. Our benchmarks — <a href="/articles/tanqueray-london-dry-gin-review">Tanqueray</a> and <a href="/articles/sipsmith-london-dry-gin-review">Sipsmith</a> — are actually distilled in Scotland and London respectively.
M
Maceration (Steeping)
Soaking botanicals in the base spirit before (and sometimes during) distillation to extract their oils and flavours. The most traditional method of flavouring gin.
N
Neutral Grain Spirit
The clean, high-proof, flavourless base spirit (usually from grain) that gin is built on. Botanicals are distilled with it to create gin — the quality of the base matters more than marketing admits.
New Western / Contemporary Gin
Modern gins that dial juniper back and push other botanicals — citrus, floral, cucumber, tea — to the front. Softer and more approachable than London Dry.
This is the style that made gin cool again. <a href="/articles/hendricks-gin-review">Hendrick's</a>, with its cucumber and rose, is the poster child — delicious, but juniper takes a back seat.
Contemporary gins are lovely, but juniper-light and often premium-priced. Know when you're paying for a marketing-led style rather than classic gin backbone.
O
Old Tom Gin
A historic, slightly sweetened style of gin that sits between juniper-forward London Dry and the malty Dutch genever. The traditional base of a Tom Collins and a Martinez.
One-Shot vs Multi-Shot
Two ways to scale gin. One-shot uses the exact botanical ratio in every batch; multi-shot distills a concentrated botanical batch and dilutes it with more neutral spirit later. One-shot is often a craft badge of honour.
P
Plymouth Gin
A historic style made only in Plymouth, England — softer, earthier, and rounder than London Dry, with more root botanicals and a signature smooth texture.
The insider's classic, specified by name in countless old cocktail books. See our <a href="/articles/plymouth-gin-review">Plymouth review</a> for why it makes a silkier Martini.
S
Sloe Gin
Not a gin but a gin-based liqueur, made by steeping sloe berries (blackthorn fruit) and sugar in gin. Rich, red, and fruity — a winter classic.
Supporting Botanicals
The classic co-stars behind juniper: coriander seed (citrus-spice), angelica root (earthy, binds the botanicals), orris root (floral, a fixative), and citrus peel. The backbone of most London Dry recipes.
T
The Cut (Heads, Hearts, Tails)
The distiller's selection of which part of the run to keep. Heads (harsh, volatile) and tails (heavy, oily) are discarded or recycled; the clean 'hearts' become the gin. Where the cuts are made shapes the final character.
V
Vapor Infusion
A method where botanicals are suspended in a basket above the boiling spirit, so only the rising vapour passes through them. Gives a lighter, more delicate, aromatic gin than steeping.
