How Botanicals Shape Gin

If juniper is the backbone of gin, then the supporting botanicals are the flesh, muscle, and skin that give it character. They provide the depth, balance, and individuality that distinguish one brand from another. While juniper must always lead, it is the interplay with coriander, angelica, citrus, spices, herbs, and increasingly exotic ingredients that defines the spectrum of gin styles.

The Classic Gin Trinity

Most gins are built on a triad of botanicals, sometimes called the “gin trinity”:

• Juniper: The defining piney, resinous core. Without it, gin ceases to be gin.

• Coriander Seed: A close second in importance. Coriander seed contributes linalool (citrus, floral) and decanal (warm, spicy, nutty). In many gins, coriander amplifies citrus while adding spice depth.

• Angelica Root: Earthy, musky, slightly bitter. Contains lactones and coumarins that “fix” and bind volatile compounds, stabilising aromas. Without angelica, gin flavours often feel disjointed.

Together, these three botanicals form the foundation of most gin recipes. Adjusting their ratios can radically shift balance: coriander-heavy gins lean citrus-spice, while angelica-heavy gins become more earthy and savoury.

Secondary Anchors

Beyond the trinity, several botanicals frequently anchor gin flavour profiles. These core botanicals ensure gins have structure, body, and recognisable “gin-ness.:

• Orris Root: Floral, powdery violet character; excellent fixative. Used sparingly, but powerful in smoothing flavour arcs.

• Citrus Peels: Lemon, orange, grapefruit peels provide limonene and citral for brightness. Tanqueray No. 10 famously distills fresh citrus for its crisp lift.

• Cassia Bark & Cinnamon: Add warmth and depth, leaning into sweet spice.

• Licorice Root: Earthy sweetness, increases perceived body and length.

Creative Modern Botanicals

Distillers are expanding the palette with terroir-driven and unusual additions, crafting gins that showcase a strong sense of place and creativity. Hendrick’s in Scotland highlights cucumber essence for a cool freshness and rose petals for a floral lift, while Ki No Bi from Japan layers bright yuzu peel, umami-rich gyokuro tea, and tingling sansho pepper. Four Pillars in Australia leans on native botanicals such as lemon myrtle for an intense citral burst and Tasmanian pepperberry for fruity spice. St. George Terroir in California evokes a pine forest with Douglas fir, bay laurel, and sage, and Germany’s Monkey 47 pushes complexity with a staggering 47 botanicals, including lingonberry, acacia, and spruce tips.

Science of Botanical Extraction

Each botanical contributes different volatile compounds with unique boiling points and solubilities. Scientific control matters: excessive heat volatilises delicate esters; poor cut points capture bitter or woody fractions. Distillers must decide how to extract them:

• Maceration: Harder botanicals (roots, seeds) steep in diluted spirit for hours before distillation. This extracts oils thoroughly but risks heavy flavours.

• Vapour Infusion: Delicate botanicals (flowers, peels) are placed in baskets above the still. Vapour gently carries aromatic oils, preserving bright, volatile notes.

• Split Charging: Roots and seeds are macerated, while flowers and citrus are vapour-infused in the same run. Tanqueray No. 10 is a benchmark example.

Distillers set cut points based on when juniper is strongest relative to citrus and spice. Analytical tools like GC-MS confirm where compounds concentrate, allowing benchmarking and recipe fine-tuning. Botanicals release flavours at different stages of the distillation run due to volatility:

• Early: Citrus terpenes (limonene, citral).

• Middle: Juniper terpenes (α-pinene, sabinene).

• Late: Earthy lactones (angelica), sweet glycyrrhizin (licorice).

Sensory Interplay: Building Balance

Distillers talk of building gin like composing music. Juniper provides the bassline, coriander the rhythm, and secondary botanicals the melody. Well-constructed gins achieve balance: no single note dominates, but juniper always remains the anchor. The art lies in harmony:

• Citrus vs. Spice: Bright limonene from lemon peel must be balanced against coriander’s warm linalool.

• Floral vs. Earthy: Orris and lavender can soar, but angelica and licorice ground them.

• Sweet vs. Dry: Cassia and licorice sweeten perception, while juniper and citrus drive dryness.

Brand Examples: Botanical Signatures

• Tanqueray London Dry: Classic trinity, juniper-heavy, minimal botanicals, crisp and clean.

• Beefeater: Juniper balanced with bright Seville orange peel and subtle licorice.

• Bombay Sapphire: Vapour-infused botanicals (almonds, grains of paradise, cubeb berries) for delicacy.

• Monkey 47: Maximalist approach, layering forest, spice, fruit, and herb into a complex profile.

• Nolet’s Silver: Radically floral, with Turkish rose, peach, and raspberry.

These contrasts show how distillers “tune” the botanical spectrum to craft unique house styles. I see gin as a balance of volatility management and sensory artistry. Botanicals are not simply ingredients; they are volatile chemical systems. A coriander-heavy gin can read as lemony at one cut point, but nutty at another. A poorly stored batch of angelica can flatten an otherwise bright recipe.

The best gins, whether the restrained juniper wallop of Tanqueray, the delicate infusion of Bombay Sapphire, or the botanical maximalism of Monkey 47, succeed not because of their ingredient lists, but because of how they control extraction and balance interplay.

Botanicals are gin’s soul. They allow distillers to innovate endlessly while respecting juniper’s dominance. The interplay of coriander, angelica, citrus, and spice creates diversity across the category, from classic London Dry to avant-garde terroir gins.
