Gin Construction
Gin is a designed spirit: a base, a botanical recipe, and a series of choices that decide what reaches your glass. Learn the process and you will read a bottle, menu, or tasting note with much more confidence.
1. Base spirit
Most gin starts with a neutral agricultural spirit made from grain, grape, molasses, potato, or another fermentable crop. The base is deliberately quiet so juniper and the supporting botanicals can lead, although a grain or grape base can still add a subtle texture.
2. Botanicals
Juniper must be the defining flavour for a spirit to be called gin. A distiller then builds around it with citrus peel, coriander, roots, seeds, flowers, tea, herbs, spice, fruit, or local ingredients. Think of juniper as the spine, the supporting botanicals as the body, and the aromatic accents as the finish.
3. Maceration
Maceration rests botanicals in the spirit so alcohol can draw out their oils and flavour. Dense ingredients such as roots, seeds, and berries often need more time than delicate flowers or fresh citrus. Time, temperature, and dosage all change the result.
4. Vapour infusion
In a vapour basket, the heated spirit carries vapour through delicate botanicals rather than soaking them directly. This can preserve lifted floral, citrus, and fresh-herb aromas. Many gins combine vapour infusion with maceration to balance depth and brightness.
5. Distillation
The still separates and concentrates volatile aromas. The distiller decides which part of the run becomes the final spirit: early heads can be sharp, the middle heart is usually cleanest, and late tails can bring heavier or rougher notes. Copper stills can also help soften certain sulphury compounds.
6. Proof and ABV
ABV means alcohol by volume. A distillate often leaves the still stronger than the bottle strength, so the distiller adds water to proof it down. A higher ABV can carry more aroma and texture, while a lower ABV may feel softer and easier in a long drink; neither automatically means better.
7. Blending and filtration
Separate batches or botanical distillates can be blended to make a consistent recipe or create layers of flavour. Filtration removes haze and particles, but aggressive filtering can also strip texture. A little natural cloudiness is not automatically a flaw, especially when essential oils are present.
8. Aging and finishing
Unlike whisky, gin does not need oak aging. Some producers rest gin in wood or use casks to add vanilla, spice, tannin, and colour. Others finish with tea, fruit, sugar, or a second botanical infusion. Look for the finishing choice when you want to understand why a gin feels rounder or more unusual.
Try this: When tasting a new gin, read the ABV and botanical list first, then guess whether it will feel bright, resinous, floral, spicy, or savoury before you take a sip.
