Gin botanicals are where every last drop of gin's flavour comes from, which is a remarkable thing when you stop and think about it. Take away the juniper berries, the citrus peel and the quiet background spices, and gin is simply a neutral spirit with good marketing. That's not a criticism, it's the magic: one plain spirit becomes a thousand different drinks depending on what a maker chooses to steep in it. This guide looks at what actually counts as a botanical, why juniper is the one ingredient no gin can do without, what the supporting cast of citrus, spice and floral botanicals each bring to your glass, and how to balance a blend until it tastes recognisably, and rather proudly, yours.
What are gin botanicals?
A botanical is any part of a plant used to flavour a spirit. Berries, seeds, dried peels, roots, barks, herbs and whole flowers all qualify, and a gin's recipe, sometimes called its botanical bill, is simply the list of which ones the maker chose and in what proportions. Juniper always leads. Around it, most gins gather a handful of supporting botanicals, and some gather dozens.
Commercial distilleries usually redistil the spirit after adding their botanicals, which is how shop-bought gin ends up crystal clear. At home, the botanicals go straight into the spirit and infuse there, a method known as compound gin, and it's the easiest, safest and only legal way to make gin in a British kitchen without a distiller's licence. Nothing else is required: no sugar, no sweeteners, no flavourings. The blends in our kits contain none of those things, because the juniper and botanicals carry all the flavour a proper gin needs.
If you'd like to see how far a botanical bill can stretch, our Ultimate Gin Making Kit is a gin botanicals set built around juniper plus 13 botanicals, with measuring spoons and tasting pipettes included so you can blend like a distiller rather than guess like a gambler.
Why can't gin do without juniper?
Because without juniper, it isn't gin. The word itself descends from juniper, by way of the Dutch jenever, and the defining rule of gin everywhere is that juniper leads the flavour. Everything else is negotiable. Juniper is not.
So what do juniper berries actually taste of? Pine, first and foremost: a fresh, resinous, walk-in-a-forest sharpness, with a peppery warmth underneath and a faint citrus edge that helps every other botanical make sense around it. Juniper is the reason a G&T tastes bracing rather than merely boozy.
Every infusion in our kits is built the same way: juniper berries plus the botanical blend. If you're mixing a blend of your own, a good rule of thumb is 10g of juniper berries per 700ml batch, and whatever else you experiment with, don't leave it out. A gin with timid juniper isn't a subtle gin, it's flavoured vodka with ideas above its station.
What do citrus, spice and floral botanicals bring to your glass?
If juniper is the lead singer, the rest of the botanical bill is the band, and each section has a job to do.
Citrus botanicals: the brightness
Dried lemon and orange peel are the workhorses of citrus in gin. The flavour lives in the oils of the peel, and steeping releases them slowly into the spirit, along with a light amber tint that's the honest signature of a home-infused citrus peel gin. Lemongrass plays in the same section with a greener, more fragrant sort of brightness. The blend in our classic Gin Making Kit is built exactly this way: bright citrus from lemongrass, lemon and orange peel, lifted by fragrant coriander and allspice, and designed to echo a premium London-style gin. One tip worth stealing: fresh peel, cut into long strips with a vegetable peeler, gives an even brighter citrus note than dried.
Spice botanicals: the warmth
Coriander seed is gin's great quiet achiever, and after juniper it's probably the most used botanical in the world's gins. It doesn't taste of the leafy herb at all; the seed brings a warm, gently citrusy spice that bridges the gap between juniper's pine and the peel's brightness. Allspice adds a rounder, clove-and-nutmeg sort of warmth. Distillers reach for plenty of others, cardamom, cinnamon and black pepper among them, but the principle never changes: spice botanicals are the seasoning, not the dish, and a little carries a long way.
Floral botanicals: the flourish
Flowers bring perfume, softness and, occasionally, a party trick. Lavender, elderflower and chamomile are familiar floral notes in commercial gins. The most theatrical flower of all is the blue pea flower, the star of our Colour Changing Gin Kit, which contains a natural dye that responds to acidity: the gin infuses to a deep blue, then turns pink or purple the moment the tonic hits the glass. Nothing artificial anywhere, just botany showing off.
How do you balance gin botanicals in a blend?
Think of a blend as a pyramid. Juniper is the wide base, the backbone every other flavour stands on. Citrus forms the generous middle. Spice and floral botanicals sit at the narrow top in small, deliberate amounts, because they're the loudest voices in the room and the easiest to overdo.
A few practical rules keep home blends on the rails:
- Use whole botanicals, never powders. Ground spices are almost impossible to strain out and will cloud your gin.
- Go easy on dried ingredients. No more than about a teaspoon of any one addition, so nothing overwhelms the blend.
- Measure properly. Level measuring spoons make a blend repeatable, so when you hit on a good one you can make it again.
- Keep the juniper constant. Experiment around it, not instead of it.
If you want a proven starting point for your own botanicals for gin, try this per 700ml batch: the peel of a quarter of an orange, the peel of half a lemon, half a teaspoon of allspice and half a teaspoon of coriander seeds, plus your 10g of juniper berries.
And if a batch misses the mark? It's fixable. Too weak means it needed longer to steep, or a touch more botanicals next time. Too strong or harsh means it infused too long: strain earlier next time, or soften this batch by topping it up with a little more vodka.
How do you taste your way to your own signature gin?
With a pipette and a little patience. Infusion is a wonderfully transparent way to make gin: the flavour builds day by day, and you can taste as you go by drawing a small sample with the pipette. The longer the botanicals steep, the stronger the flavour, so you simply strain them out the moment it tastes right to you. You are in control of the whole thing.
Timings vary by blend. The colour-changing gin is ready in about 12 hours, the Ultimate kit in a couple of days and the standard kit in under a week. Days, not weeks, in every case, and the little bit of patience really pays off in the flavour.
This is where the Ultimate Gin Making Kit earns its name. With juniper plus 13 botanicals to mix and match, and enough to make up to ten 700ml bottles, every batch can be a different experiment: one leaning citrus, one leaning spice, one straight down the middle, until you land on a signature blend that's yours alone. The kit includes a metal sieve, measuring spoons, tasting pipettes, a silicone funnel, and bottle tags with string; you just add a bottle of inexpensive vodka per batch.
And once the kit's botanicals are used up, don't stop. Take what you've learned, raid the spice rack and the fruit bowl, and make the recipe entirely your own. That isn't us being generous, it's rather the point of the whole hobby.
Gin botanicals FAQs
How long should gin botanicals infuse?
Days, not weeks. Our colour-changing gin infuses in about 12 hours, the Ultimate kit in a couple of days and the standard kit in under a week. Taste as you go with the pipette and strain the botanicals out once the gin tastes right to you.
Is it legal to make botanical gin at home?
Yes, completely, and no licence is needed. Steeping juniper and botanicals in a spirit you already own is perfectly legal. Distilling your own spirit without a licence is illegal in the UK, which is exactly why our kits don't do it.
Do gin botanicals contain any sugar or sweeteners?
Ours contain none. Every bit of the flavour comes from the juniper and botanicals themselves, with nothing added.
Why has my botanical gin turned amber?
It's completely normal. Home-infused gin is a compound gin, and the dried orange and lemon peel lend a light amber colour along with their flavour. Clear commercial gins are redistilled after the botanicals go in, which leaves the colour behind and can't legally be done at home.
My gin looks cloudy. Is that the botanicals?
A slight haze from natural botanicals is normal. Strain the gin again through a sieve or filter bag without squeezing, then chill it. It won't affect the taste at all.
What can I do with leftover juniper berries?
Juniper ice cubes. Pop a couple of berries into each section of an ice cube tray, top up with water and freeze. They look fantastic in a G&T, and the berries float up as a garnish as the ice melts.
