Whisky & Tonic Highball
Few whisky serves generate more surprise than whisky and tonic. For many drinkers, tonic belongs exclusively with gin, yet its combination of bitterness, citrus and carbonation can work beautifully with the right whisky. The Whisky & Tonic Highball is crisp, refreshing and quietly complex, making it one of the most overlooked serves in the whisky world.
The secret lies in balance. The tonic should complement the whisky rather than dominate it, allowing fruit, vanilla and spice notes to emerge whilst adding a refreshing bittersweet edge. The result is a Highball that feels familiar enough to be approachable, yet different enough to spark conversation.
Whilst gin and tonic may dominate modern drinking culture, tonic water has been paired with a wide variety of spirits for generations. Whisky and tonic has remained something of a hidden gem, often discovered by accident rather than design. Yet many lighter whiskies possess exactly the characteristics needed to work with tonic’s distinctive bitterness.
The rise of premium tonic waters has only improved matters further, offering drinkers a wide range of styles that can be tailored to different whiskies.
For those looking to challenge their assumptions about whisky, this might be the perfect place to start.

Flavour Profile & Experience
The Whisky & Tonic Highball is bright, crisp and surprisingly sophisticated.
The tonic water introduces a gentle bitterness that highlights citrus and fruit notes within the whisky, whilst the carbonation creates a light, refreshing texture. Depending on the whisky selected, expect flavours of orange peel, vanilla, honey, orchard fruit and soft spice.
The finish is long, clean and remarkably refreshing.
Variations & Modern Twists
Mediterranean tonic water can introduce subtle herbal notes that pair beautifully with lighter whiskies.
For a brighter citrus profile, add a thin slice of pink grapefruit alongside the orange twist.
Those looking for a slightly sweeter serve can experiment with elderflower tonic water.
A sprig of rosemary can also work well with whiskies showing more pronounced oak and spice.
The Whisky & Tonic Highball works best with lighter, fruit-forward whiskies that offer citrus, vanilla and orchard fruit character. Heavy sherry influence or intense smoke can sometimes clash with tonic's bitterness, so a lighter style is generally the better choice.
🥃 Summerton Recommends
Fettercairn 16 Years Old – 3rd Release
Matured in a combination of Oloroso Sherry, Pedro Ximénez Sherry and ex-Bourbon casks, this 16-year-old Fettercairn delivers layers of honeyed orchard fruit, dried apricot, toasted oak and warming spice. The balance of rich fruit and gentle sweetness makes it a superb Highball whisky, retaining its distinctive Highland character while allowing fresh citrus or sparkling mixers to lift the whisky rather than overpower it.
Not all tonic waters are created equal. A high-quality tonic such as Fever-Tree Indian Tonic Water, Double Dutch Indian Tonic or Franklin & Sons Natural Indian Tonic will generally produce a cleaner, more balanced result than standard supermarket alternatives.
The Whisky & Tonic Highball pairs beautifully with seafood, grilled chicken, charcuterie, light pasta dishes and summer salads. The bittersweet finish also makes it an excellent aperitif before a meal.
With Thanks
The #SummertonHighballRevival was created to showcase just how versatile whisky can be, and we’d like to extend our sincere thanks to two companies who helped bring this project to life.
Double Dutch Drinks
A great Highball deserves a great mixer. Double Dutch kindly supplied a selection of their premium tonics, sodas and mixers for our photoshoot, allowing us to explore flavour pairings that complement, rather than overpower, the whisky. Their range demonstrates just how much difference a thoughtfully crafted mixer can make to a Highball.
Glencairn Crystal
Beautiful drinks deserve beautiful glassware. Glencairn generously supplied a selection of their stunning Highball glasses for the campaign, including the Edinburgh and Jura collections. Their expertly crafted crystal allowed every serve to be presented exactly as it should be—elegant, timeless and made to be enjoyed.
