The Highball
A spirit, a much larger volume of something cold and fizzy, and ice. The simplest shape in the book, and the one with the least room to hide a mistake.
The formula
40 ml : 120 ml : 230 g
- Spirit
- One part, and a smaller pour than any stirred drink takes. It is not being diluted so much as flavoured outwards: the spirit has to survive three times its own volume of something else, which is why highballs favour bottles with a loud, single idea rather than subtle ones.
- Mixer
- Three parts, and the slot that names the drink. It supplies the bubbles, most of the sugar and all of the length. Its carbonation is an ingredient in its own right, which is why the mixer goes in last and is never stirred hard.
- Ice
- Not a garnish and not optional. A full glass of ice melts more slowly than a half-full one, so the drink that looks over-iced is the one that stays undiluted; skimping here is the single most common way to make a watery highball.
One to three is the shape, and the absolute figures are what a standard tall glass will actually take. That is the constraint nobody writing a highball recipe mentions: a glass packed with cubes has only about two fifths of its capacity left for liquid, so a 400 ml Collins holds a 160 ml drink and not the 200 ml the same ratio would suggest. A longer pour is not a bigger recipe, it is a bigger glass, which is exactly why the Spanish gin and tonic is built in a 650 ml balloon. Members run from about one to two at the strong end to one to four at the long end, and the ones built from two bitter aperitifs rather than a base spirit depart from the shape entirely. Each member's own page carries its real figures.
Pour a spirit into a tall glass, fill it with ice, top it with something cold and carbonated, and stir once. There is no technique here worth the name, which is exactly why the family is worth a page: everything that can go wrong goes wrong in the handling rather than in the recipe.
The spirit is a single part and a modest pour. A highball is not a weakened version of a stronger drink; it is a different intention, in which a spirit is stretched to something you can drink for an hour. That stretching is unforgiving of subtlety. A bottle whose interest lies in a slow finish loses that finish under carbonation and cold, so the family belongs to spirits with an immediate, declarative character: a botanical gin, a smoky Scotch, a bitter amaro, a rum with molasses still audible in it.
The mixer is three parts and does most of the work. It is where the sugar is, where the acid is when there is any, and where the bubbles are. Carbonation is not decoration: it carries aroma up out of the glass, and it makes a sweet mixer taste less sweet than the same liquid flat. This is why a highball made with a mixer that has gone soft is not a slightly duller drink but a noticeably sweeter one.
The ice is the third slot and the one people cut. Ice does two jobs at once and they pull against each other: it chills, which costs dilution, and it insulates what is already chilled, which prevents it. A glass packed to the rim has less liquid surface exposed and a lower net melt rate than a glass with three cubes rattling in it, so the correct answer to "how much ice" is always "more". Cold mixer helps for the same reason: every degree the mixer is above freezing is paid for in melted ice.
The order matters more than in any other family. Spirit first, ice next, mixer last, and one gentle lift with a bar spoon rather than a stir: carbonation knocked out of the drink during building does not come back, and a highball stirred like an Old Fashioned arrives flat.
The family's members diverge on what the mixer is rather than on what the ratio is. Soda water adds nothing but length and bubbles, and leaves the spirit to carry the drink alone. Tonic adds quinine's bitterness and a real quantity of sugar, which is why it flatters gin's botanicals and overwhelms quieter spirits. Ginger beer brings its own heat. Cola brings sweetness, acid and caramel at once, and is doing more of the work than its reputation suggests. A handful of members replace the base spirit with two bitter aperitifs in equal measure and top that instead, which is where this family and the Old Fashioned's bitter-slot branch meet.
