Fever-Tree Refreshingly Light Cucumber Tonic Water
A light tonic flavoured with cucumber and, less obviously, with lemon. It exists only in the Refreshingly Light form, sweetened with fructose at 18 kcal per 100ml, and it is the tonic built for gins that already lean towards cucumber.
Quick Facts
Flavour Profile
Primary Flavours
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.
Storage & Handling
Store unopened bottles in a cool, dry place. Refrigerate before use. Once opened, use immediately to retain carbonation and freshness.
Shelf Life
Unopened: 6–12 months. Opened: Use immediately
Usage
Poured at 150ml to 200ml over 50ml of a cucumber-led or crisply floral gin. It also works over vodka as a long, low-sugar summer drink, and it will disappear underneath anything heavily juniper-driven or barrel-aged.
Cucumber and Lemon
The ingredients name natural cucumber and lemon flavourings together, which is worth knowing because the lemon does more than the label’s billing suggests. Cucumber on its own is a faint, watery note that struggles to carry a drink, and the lemon gives it an edge and stops it reading as flat. There is no cucumber juice or extract here, only flavouring, so this is a tonic that tastes of cucumber rather than one made from it. That is an ordinary way to build a soft drink and not a criticism, but it is not the same claim.
Light Only
Unlike the Indian and Mediterranean tonics, there is no full-sugar version of this to compare it against. It is made in the Refreshingly Light form alone, sweetened with fructose, at 18 kcal and 4.4 grams of sugar per 100ml. That places it below the standard Indian tonic on both counts and roughly level with the other light bottles in the range. The consequence is a thin, dry drink by design, and anyone expecting the roundness of a full-sugar tonic will find this sharper than they wanted it to be.
Which Gin
The obvious pairing is a gin that already carries cucumber, and the obvious objection applies, since doubling a botanical usually flattens it rather than doubling it. In practice it works here, because the tonic’s cucumber is faint enough to extend the gin’s rather than compete with it. A crisp, floral or citrus-led gin is the safer choice and gains a cooling note it did not previously have. A heavy London Dry or a barrel-aged gin simply walks over the top of it.
Serving It
Cold and over a full glass of ice, poured down the side. Garnish is where this goes wrong most often. A ribbon of cucumber looks right and adds almost nothing, since cucumber gives up very little in cold liquid, and the drink already carries the note. A strip of lemon peel does more, and it echoes what is genuinely in the bottle. It comes in 150ml, 200ml and 500ml, and the small ones are the ones to buy.
Pro Tip
If a drink tastes thin, increase ice quality before increasing tonic volume.
Top Tips
- Read the label properly. There is lemon flavouring in here as well as cucumber, and it is doing real work.
- Do not expect a full-sugar version. This is made only as Refreshingly Light, so it runs dry and thin by design.
- Garnish with lemon peel rather than cucumber. The peel adds something the bottle has not already given you.
Possible Substitutions
- Soda water with fresh cucumber (drier, less aromatic)
Production Method
Produced by carbonating spring water and blending with natural cucumber extracts, quinine, citrus notes, and fruit sugars before bottling under pressure.
History & Context
Cucumber has long been associated with cooling gin serves. The refreshingly light format modernises the pairing by reducing sweetness while maintaining freshness and balance.
Common Questions
What does cucumber tonic pair with?
A crisp, floral or citrus-led gin, which gains a cooling note it did not have, and a cucumber-led gin, where the tonic extends the botanical rather than competing with it. Vodka works for a long, low-sugar drink. A heavy London Dry walks straight over it.
Is it sweet?
Less than most tonics. It is made only in the Refreshingly Light form, sweetened with fructose at 4.4 grams of sugar per 100ml against 7.4 in the standard Indian tonic, so it reads dry and thin. That is the design rather than a shortfall.
What garnish suits it?
A strip of lemon peel, which echoes the lemon flavouring genuinely in the bottle. A ribbon of cucumber looks correct and contributes almost nothing, because cucumber gives up very little in cold liquid. Nothing at all is also a reasonable answer here.
Is there real cucumber in it?
No. The ingredients list natural cucumber and lemon flavourings rather than a juice or an extract, so it tastes of cucumber rather than being made from it. That is a normal way to build a soft drink, and it is worth knowing before paying for the impression of freshness.
