Ingredients & Techniques
The Japanese highball, made with intent
A trade show full of espresso, matcha, and ultra-refined serves keeps circling a drink Japan settled decades ago: whisky, soda, and the temperature you pour them at.
The takeaways from Bar Convent Brooklyn this month read like a list of additions. Caffeine-forward flavors were everywhere, with espresso and matcha running across full-proof, low-ABV, and no-ABV serves. Bartenders leaned into savory, ultra-refined cocktails, house ferments, and unexpected botanicals. Underneath the new flavors sat a plainer reality the show kept naming: running a bar in a tight economy means watching every pour, every ounce of waste, and every minute behind the stick.
It is worth pointing out that the drink which answers most of those pressures at once is not new at all. The Japanese highball is whisky and soda. It is fast to build, cheap on labor, light enough to sit beside food for an evening, and refined precisely because nothing hides a careless one. The trade show floor was chasing restraint. Japan has been serving it for the better part of a century.
Why two ingredients earn this much attention
A highball is whisky lengthened with soda water, usually one part spirit to three or four parts soda. With so little in the glass, every variable that a busier cocktail would mask becomes the drink itself: the temperature of the whisky, the size and clarity of the ice, the freshness of the carbonation, and how much you disturb it on the way out. Get those right and the result is clean, dry, and aromatic. Get them wrong and you have warm, flat, watered whisky.
This is the same logic that governs a good dashi or a bowl of rice. When the components are few, technique stops being decoration and becomes the entire margin between flat and excellent.
The method, step by step
The version below follows the approach Japanese bartenders are known for: everything cold before it meets the glass, and the fewest movements that will mix it.
For one highball
- Japanese whisky45 ml
- Chilled soda water135–180 ml
- Clear icetall glass, filled
- Lemon peel (optional)1 strip
- Chill everything first. Keep the glass in the freezer and the whisky and soda cold. The colder the start, the less the ice melts, and the longer the drink holds its line.
- Fill the glass with ice. Large, clear cubes melt slowly and keep the soda from going flat. Pack the glass full rather than half, which seems backward until you taste the difference.
- Add the whisky and stir once. Pour the spirit over the ice and give it a single, gentle turn with a bar spoon to chill it through before the soda goes in.
- Pour the soda down the side. Tilt the glass and pour against the ice so the carbonation stays in the liquid, not in the air. Aim for three to four parts soda to one of whisky.
- One vertical lift, then stop. Slide the bar spoon to the bottom, lift straight up once, and remove it. That single move folds the whisky through without beating the bubbles out. Express the lemon peel over the top if you like.
Where it belongs: the izakaya table
The highball is a food drink, which is the other reason it travels so well. In an izakaya, pitchers of it move alongside plates meant for sharing, and its dryness does real work at the table. The clean fizz cuts the fat of karaage, resets the palate between bites of tempura, and stands up to the smoke of grilled skewers and eel without competing with them. It asks nothing of the kitchen and flatters almost everything that comes out of it.
That is the quiet argument the trade show kept making without quite saying it. As bars look for serves that are refined, low in alcohol when the guest wants it, and honest about cost, the highball was already there.

Make it once with cold glass and good ice and the appeal is obvious. The newest idea on the bar this year turns out to be one of the oldest, poured carefully. More on how we work is on our about page, or browse the rest from the home page.
