Mizuwari
A Mizuwari is 45ml Japanese whisky and 90ml cold still water in a glass packed with ice: whisky first, stirred to chill it, then the water, stirred again. The name means cut with water, and at one part whisky to two of water it holds about 1.8 UK units, long and cool. It is the still partner of the Japanese highball, and in Japan it is drunk at the table, alongside food. Our method stirs the whisky on its own before the water goes in, then a few turns more. The ice and the water do different jobs. A full glass of ice chills the whisky; the measured water dilutes it, to a strength you choose rather than one the melting ice decides.
Glassware: Highball Glass
Garnish: None
Ingredients
45ml
A Japanese blended whisky, bottled at 40% ABV or stronger. Any good, gentle malt or blend works; heavy peat takes over once the water opens it up.
90ml
Cold, still and soft, ideally filtered or a soft bottled water. At 90ml it makes up two parts in three of the drink, so chlorinated tap water shows.
Instructions
Fill a highball glass to the brim with clear cubed ice.
Pour in the whisky and stir slowly, about 13 turns, until the glass is cold.
Top up the ice if it has sunk.
Add the cold still water and stir a few turns more.
Serve at once, with food if there is any.
Expert Tip
Pack the glass to the brim with ice before anything else. A packed glass chills fast and melts slowly; three cubes melt into the drink and leave it warm and thin. Stir the whisky on its own first, slowly, until the glass frosts. The count matters less than the order: chill first, then dilute. Use cold water you would happily drink on its own, soft and still. At two parts in three, the water is most of the glass.
Behind the Mizuwari
Flavour Profile
The Origin
Mizuwari means cut with water, and the serve is as plain as the name: whisky, ice and still water. In Japan it grew up beside the highball as a way to drink whisky long and cold, with food.
That is a different habit from the small, strong measure sipped after dinner. A long glass holding about 1.8 UK units suits a meal, and Difford’s Guide says diners in Japan drink mizuwari in place of wine with their meals, at a ratio of whisky to water that varies between 1:2.5 and 1:4.
The Dilution Argument
A drop of water opens a whisky in a tasting glass. The mizuwari takes that idea much further, to two parts water for every part of whisky.
At that strength the cereal, fruit and floral notes come forward and the heat of the alcohol drops away. Gentle Japanese blends suit it for that reason.

Ice and Water Do Different Jobs
The usual mistake is to treat the ice and the water as one thing. A packed glass of ice chills the whisky quickly and then melts slowly; the water dilutes it, to a measure you choose.
Rely on ice alone and you wait for the drink to cool while its strength keeps changing. Chill first, dilute second, and the drink holds steady.
Against the Highball
Soda lifts the aroma towards the nose and adds a prickle, which makes the highball brisk. Still water takes that away and leaves the whisky softer and closer.
For the sparkling version, the Whiskey Highball tops the whisky with soda over the same packed ice.
How to Serve It
With food, in a tall glass packed with ice. It suits a long meal and refills well.
Choose the water as carefully as the whisky. With two ingredients, and one of them water, there is nowhere else for the flavour to come from.

The Spirit
Whisky (Japanese)Japanese whisky is whisky made in Japan, usually from malted barley and other grains, and, under the Japan Spirits and Liqueurs Makers Association standard, bottled at a 40% ABV minimum, the strength our recipe assumes. Since April 2024 members of the Japan Spirits and Liqueurs Makers Association give the name only to whisky distilled, aged three years and bottled in Japan, under a voluntary trade standard rather than a law. Our recipe for it is the Mizuwari, whisky lengthened with still water.

Whiskey Highball
A Whiskey Highball is 50ml Scotch whisky and 100 to 125ml cold soda water in a highball glass packed with ice, stirred once, with a strip of lemon peel twisted over it. About 2.0 UK units. With two ingredients, everything rests on the whisky, the soda and how cold both are. The Oxford Companion says whisky and soda crossed to America, where by 1895 it was rapidly edging into the mainstream under the name Scotch Highball. Where the word comes from is disputed: a tall glass, or one of the senses it had in baseball, poker and railroads. In Japan, where the highball means whisky and soda water, Suntory’s master blender Shinji Fukuyo told The Spirits Business that the highball campaign succeeded in the late 2000s, maybe 2008. The method exists to keep the bubbles: cold glass, cold soda, a gentle pour and one stir.
Presbyterian
A Presbyterian is 50ml of rye whiskey over ice in a highball glass, topped with 60ml each of ginger ale and soda water poured in together, stirred once and finished with a lemon twist. About 2.0 UK units. The split top is the recipe. Ginger ale on its own makes a sweet whisky and ginger; soda on its own makes a plain highball. Half and half keeps the ginger as a seasoning and the drink dry. Its history is thin. Difford’s Guide calls it a traditional British highball of blended Scotch and says the name may come from the Greek presbýteros, “elder”, noting that the Presbyterian Church originated primarily in Scotland. Other writers suggest a joke at the expense of abstemious Presbyterians. We have found no source that documents either guess or names a first recipe or creator. Difford’s Guide says it should be made with Scotch rather than rye; ours uses rye, because in our view its pepper suits the ginger.
Hot Toddy
A Hot Toddy is 60ml Scotch, 15ml honey syrup, 15ml fresh lemon juice and 120ml water just off the boil. Stir the honey syrup, lemon and water in a warmed mug, add the whisky last, and finish with a clove-studded lemon wheel and a cinnamon stick. About 2.4 UK units. The Oxford Companion says the toddy’s origin is murky and does not appear to be linked to the South Asian palm wine of the same name, that it first appears in print in England in 1741, and that Scotland made the drink an institution, particularly the hot version. In our view, made with Scotch it is the version most tied to Scotland. Restraint is the method. Water just off the boil keeps the whisky’s aroma in the mug, and honey syrup mixes where neat honey sinks.
