Tasting Notes

Clean, refreshing cucumber aroma with soft bitterness and restrained sweetness. Crisp, dry finish with a cooling, vegetal note that lingers lightly on the palate.

Only ever made as a light tonic

There is no regular version to compare: Fever-Tree’s UK site lists the cucumber tonic in its Refreshingly Light form alone, at 18 kcal per 100ml. Fever-Tree's British range still carried it on 17 October 2026. The low sugar shows as a thin, dry body, which suits a crisp gin and disappoints anyone expecting a classic tonic's roundness.

Cucumber and lemon are both on the label

The ingredients name natural cucumber and lemon flavourings together. On its own cucumber is a faint, watery note that struggles to hold a drink; the lemon gives it an edge. Because both are flavourings rather than juice, fresh cucumber in the glass is what brings the smell of the vegetable itself.

Three ways to get cucumber into a gin and tonic

Refreshingly Light Cucumber Tonic

Sugar from the mixer per 100ml: 4.4g (Fever-Tree’s UK label)
Cucumber comes from: Flavouring in the bottle
Result: Cucumber through the whole drink

Indian tonic with cucumber ribbons

Sugar from the mixer per 100ml: Fever-Tree’s UK label gives its full-sugar Indian 7.4g
Cucumber comes from: Fresh ribbons only
Result: Fainter cucumber, rounder body

Cucumber tonic with ribbons

Sugar from the mixer per 100ml: 4.4g
Cucumber comes from: Bottle and glass
Result: The strongest cucumber smell

Method	Sugar from the mixer per 100ml	Cucumber comes from	Result
Refreshingly Light Cucumber Tonic	4.4g (Fever-Tree’s UK label)	Flavouring in the bottle	Cucumber through the whole drink
Indian tonic with cucumber ribbons	Fever-Tree’s UK label gives its full-sugar Indian 7.4g	Fresh ribbons only	Fainter cucumber, rounder body
Cucumber tonic with ribbons	4.4g	Bottle and glass	The strongest cucumber smell

In our Cucumber and Mint Gin and Tonic

The Cucumber and Mint Gin and Tonic folds two ribbons of cucumber into a copa, packs it with cubed ice, adds 50ml of gin and tops it with 150ml of the tonic, then finishes with a clapped sprig of fresh mint. That is the one part gin to three of tonic that Fever-Tree's own serve uses. Swap in an Indian tonic with one slice of cucumber and the green note almost vanishes.

Using it

Using Fever-Tree Refreshingly Light Cucumber Tonic Water

Usage

One part gin to three of tonic, 50ml to 150ml, over cubes, with cucumber ribbons pressed against the glass and mint clapped on top, as in our Cucumber and Mint Gin and Tonic. It lengthens vodka just as well.

Pro Tip

Fold the cucumber ribbons into the glass before the ice goes in. Trapped against the side, they stay in place and scent each sip, where ribbons dropped on top float and tangle.

Top Tips

Expect a dry, thin drink. There is no full-sugar version, and fructose at 4.4g per 100ml gives less body than a classic tonic.
Use fresh cucumber in the glass if you want its smell. The tonic carries flavouring, not juice, so ribbons add the green note on top.
Choose a crisp gin: citrus-led or floral. A heavy, oily gin covers the cucumber completely.
Serve it very cold. Warmth dulls cucumber quickly, and a lukewarm glass tastes of little but quinine.

Possible Substitutions

Tonic Water: light Indian tonic plus fresh cucumber ribbons: the same idea, a little sharper
Soda Water: with cucumber: no quinine and no sugar, a much drier drink

Production Method

Carbonated spring water, fructose, citric acid, natural cucumber and lemon flavourings with other natural flavourings, and natural flavourings including quinine, per Fever-Tree’s UK label, read 17 October 2026. There is no full-sugar version.

Common Questions

What is Fever-Tree cucumber tonic?

A light tonic water flavoured with cucumber and lemon. Its ingredients are spring water with added gas, fructose, citric acid, natural cucumber and lemon flavourings, and natural flavourings that bring the quinine. There is no alcohol in it, and three bottle sizes are sold.

Is there a full-sugar cucumber tonic?

No. Fever-Tree’s UK site lists it only as Refreshingly Light, and the British tonics list we read on 17 October 2026 has nothing else. It is sweetened with fructose at 4.4g of sugar and 18 kcal per 100ml; Fever-Tree puts it at 32% fewer calories than its Indian tonic.

Is there real cucumber in it?

The label lists natural cucumber and lemon flavourings rather than cucumber juice, and Fever-Tree describes it as cucumber essence. So it tastes of cucumber without carrying the vegetable itself. Fresh ribbons in the glass add the green smell that a flavouring alone gives only faintly.

Which gin goes with cucumber tonic?

A crisp, citrus-led or floral gin, which gains a cool, green note. A gin that already carries cucumber works too, because the tonic's cucumber is light enough to extend it. A heavy, barrel-rested or very juniper-led gin covers the cucumber, and the tonic then tastes thin.

What garnish suits a cucumber gin and tonic?

Cucumber ribbons folded against the inside of the glass and a sprig of mint clapped between the palms, which is how our recipe and Fever-Tree's own serve both finish it. Lemon peel also works, since there is lemon flavouring in the bottle. Avoid adding sweet fruit.

Is cucumber tonic still sold in the UK?

Yes. Fever-Tree’s UK site listed Refreshingly Light Cucumber Tonic Water on 17 October 2026, in 150ml, 200ml and 500ml bottles. A separate limited Summer Garden tonic also uses cucumber, with green apple, but it is a different bottle.
