Cocktail Knowledge
WHAT'S IN THE GLASS?
The Cocktail Mixer answers what to drink. The Barsurfing Map answers where. This section answers the question underneath both: what that spirit actually is, why the bartender’s hands move the way they do, and which taste a flavour tag is really naming.
Spirits
Gin
A juniper-led spirit whose flavour comes entirely from botanicals and distillation, and the busiest base in the classic canon.
Vodka
A spirit distilled to suppress the character of its raw material, judged by texture rather than aroma, and the base of many modern classics.
Rum
A sugarcane spirit that runs from light to heavy like no other category, and the backbone of tropical and sour recipes alike.
Whisky
A grain spirit matured in oak, half of whose character comes from the mash and the still and half from wood and time.
Brandy
Fruit fermented and then distilled, from cask-aged cognac to colourless kirsch, and the default base of the nineteenth-century bar.
Tequila
Mexico's blue agave spirit, from unaged blanco to barrel-rested añejo — peppery, herbal, and the backbone of the Margarita and the Paloma.
Liqueurs and herbal spirits
A liqueur is a spirit sweetened and flavoured. Orange, cherry, nut, coffee, herbal and fruit families — plus unsweetened absinthe — give a drink its character.
Vermouth and aperitifs
Aromatised fortified wines — vermouth, Lillet, Campari, amaro and port. They add bitterness, acidity and weight, and they are the first ingredients to spoil.
Bitters
Bitters are concentrated bitter infusions measured in dashes — not a drink, but the seasoning that pulls a cocktail's aroma and outline together.
Techniques
Shaking
Chilling, dilution and aeration in one action — the technique for drinks built on citrus, dairy, egg or purée.
Stirring
A bar spoon turning slowly through ice: chilling and dilution with no aeration, the method for all-spirit drinks.
Building
No shaker — the ingredients go into the serving glass in order. The method that keeps a highball bubbling.
Muddling
Pressing fruit, herbs or sugar in the base of the glass to release juice and oil — and knowing when to stop.
Layering
Stacking liquids by density so they sit in bands rather than mixing — sugar content, a bar spoon and a slow hand.
Blending
A blender drives the ice into the drink itself, giving a frozen, opaque texture — at the cost of heavy dilution.
Dry shaking
One shake without ice to emulsify egg white or cream, then a second shake with ice to chill and dilute.
Flavour words
Long reads
A short history of the cocktail
From the shared punch bowl to an 1806 newspaper definition, Prohibition, tiki, the long decline into pre-mixes, and the craft revival.
Cocktail families
Most classics are variations on a few templates. The sour, the highball, the old fashioned, the stirred drink, the fizz, the flip and the sparkling cocktail.
Home bar basics
The few tools worth owning, how ice and dilution work, measuring, what glass shapes are for, the seven techniques, and a short list of drinks to start with.
