What Is Juniper?

Juniper is a small, aromatic conifer berry (technically a cone) that gives gin its defining piney, resinous character — and it's the one ingredient every gin must contain.

Juniper berries come from the juniper shrub (a type of conifer), and despite being called "berries," they're technically small, fleshy cones. They've been used to flavour spirits since at least the medieval period, when juniper-infused spirits were valued for their medicinal reputation.

What it tastes like

Juniper brings a piney, resinous, slightly peppery and faintly citrus character. It's the flavour most people instinctively recognise as "gin-like" — if you've ever tasted a gin and thought "that tastes like a Christmas tree, in a good way," that's the juniper.

Why it's essential to gin

By definition (in most spirits regulations worldwide), a spirit must have juniper as its predominant flavour to be legally labelled "gin." That's the single feature that separates gin from other botanical spirits — a spirit made with all the same botanicals minus juniper, or with juniper only as a minor note, wouldn't legally qualify as gin.

Style differences

How dominant the juniper is varies a lot by style — see "What is the difference between London Dry and contemporary gin?" London Dry gins traditionally lean into a very upfront, classic juniper-forward profile, while many contemporary and New Zealand-style gins dial juniper back slightly to let other botanicals (especially local, native ones) share more of the spotlight, while still keeping juniper as the defining character.
