Two ingredients, a tall glass packed with ice and a twist of lemon. Done well, the soda lifts the whisky's malt, honey and hint of smoke instead of drowning it, and the drink stays bone dry and lively.

Fill a highball glass to the top with ice cubes and stir briefly to chill the glass; pour off any meltwater.
Pour in the Scotch.
Top with well-chilled soda water, pouring gently down a barspoon or the side of the glass.
Give one gentle lift with the barspoon, no more, to keep the bubbles.
Express a lemon peel over the drink and drop it in if you like.

Scotch and Soda
Taste
Crisp, dry and lightly effervescent, with malt, honey and a faint smoky note. Light enough to sip through a meal.
History and origin
Scotch and soda became fashionable in Britain in the late nineteenth century, when blended Scotch whisky spread beyond Scotland and bottled soda water was widely available. It quickly turned into a standard club and hotel drink across the British Empire.
The drink is the ancestor of the highball family, the long drinks made from a spirit and a carbonated mixer over ice. Who first called such a drink a "highball" is disputed; one often repeated claim credits the New York bartender Patrick Duffy in the 1890s, but that account rests largely on his own word.
In recent decades Japan has made the whisky highball a cult drink, with bars obsessing over ice, glass temperature and the exact way the soda is poured. The lesson applies to the humble Scotch and soda too: cold ingredients and good carbonation are everything.
Bartender tips
Ratios from 1 to 2 up to 1 to 4 all work; start around 1 to 2.5 and adjust to your whisky.
Keep the soda in the fridge and open a fresh bottle; flat soda ruins this drink.
A lightly peated blend adds depth, while a very smoky Islay malt can dominate.
Variations
Japanese-style highball
Chill glass and whisky beforehand, use large clear ice, pour highly carbonated soda very slowly and stir just once.
Scotch and ginger
Replace the soda water with ginger ale for a sweeter, spicier long drink.
Frequently asked questions
What is the best ratio for Scotch and soda?
About one part whisky to two or three parts soda. Less soda brings out the whisky, more makes it lighter and more refreshing.
Which Scotch works best?
A good blended Scotch or a light, unpeated single malt. Expensive, heavily aged malts are better enjoyed neat.
Is Scotch and soda the same as a highball?
It is one of the original highballs. Today highball describes any spirit topped with a carbonated mixer in a tall glass.
