The canned gin and tonic has gone from petrol-station curiosity to a proper category. UK off-trade sales (shops and supermarkets, not pubs) of ready-to-drink products reached £704 million in 2025, up 17% in value on the year before. That's the Wine and Spirit Trade Association's Sip 2 report, via The Spirits Business (May 2026). The quality ranges from genuinely good to barely gin-flavoured fizz. Since we make one ourselves, we're not neutral. What we can do is show you what to look at on the label, because the difference between a good canned G&T and a poor one is printed right there.
The short version
- A G&T mixed the way a decent bar mixes it lands between 8% and 10% ABV. A can at 4% or 5% is a different, lighter drink.
- Look for a named gin that exists as a bottle. Drinks over 1.2% ABV don't legally need an ingredients list in the UK, so a brand that prints one is already telling you something.
- Tonic is at least three-quarters of the drink. Sugar and natural quinine on the label beat sweeteners and "flavouring".
- Check the can size against the ABV. A 330ml can at 5% holds less alcohol than a 250ml can at 8%.
- Whatever you buy, pour it over ice in a glass.
1. Check the ABV: it tells you the recipe
A G&T poured at a decent bar is a 50ml double of 40% gin topped with 150ml to 200ml of tonic. That lands between 8% and 10% ABV (alcohol by volume). Now look at the cans on the shelf. If one says 4% or 5%, that's not a gin and tonic recipe; it's a single measure in a lot of tonic. Nothing wrong with a light drink if that's what you want. If you're expecting the drink you'd order at a bar, the ABV on the front of the can is the fastest tell.
We built our Biggar Strength Gin & Tonic (250ml, 8%, £4.50) at that strength for exactly this reason. At 8%, a 250ml can holds 20ml of pure alcohol, the same as a 50ml double of standard-strength gin. It gets there with less liquid gin than that, because the gin inside is navy strength at 57%, which is also why the juniper still shows through all that tonic.
2. A named gin, or "gin flavour"?
Here's something most people don't know. In the UK, drinks over 1.2% ABV are exempt from the ingredients list that every other packaged food has to carry. The strength and any allergens still have to be printed; the full ingredients list doesn't (GOV.UK food labelling guidance). So a can with no ingredients list isn't breaking any rules. But a brand that prints one anyway is telling you it has nothing to hide. A brand that names the actual gin, a spirit you could buy as a bottle in its own right, is telling you more still. The weaker cans say "gin" and leave it there, or build the drink from neutral spirit and flavourings.
Ours is the same Biggar Strength Gin that comes in the bottle, distilled at The Stillhouse, our distillery at the foot of Tinto Hill. The botanicals are juniper, coriander seed and cardamom, with hawthorn berry, cassia bark, rosehip, nettle, pink peppercorn and a little lavender. It scored 98 out of 100 at the IWSC in 2022, which is the number we'd rather you judged us on than anything we write here. A canned cocktail can only ever be as good as the spirit going into it.
3. The tonic is most of the drink
At a bar ratio of one part gin to three or four parts tonic, the tonic is 75% to 80% of what you're drinking. In our can, it's closer to 86%, because navy-strength gin needs less volume to do the same job. So tonic is where corners get cut invisibly: cheap sweeteners, harsh quinine, flabby carbonation. Look for two things on the label. Sugar rather than aspartame or acesulfame K, and "quinine" or "natural quinine" rather than "flavouring". Then the pour test: it should still fizz properly in the glass. If the drink tastes flat or synthetic, the gin usually isn't the culprit.
4. Check the can size against the ABV
A bigger can is not more gin. The alcohol in a can is the volume times the ABV, and the NHS counts one unit as 10ml of pure alcohol (NHS). Run the numbers and the shelf sorts itself out.
| Can | Pure alcohol | UK units | Equivalent gin measure at 40% |
|---|---|---|---|
| 250ml at 8% (ours) | 20ml | 2.0 | 50ml double |
| 330ml at 5% | 16.5ml | 1.65 | About 41ml |
| 250ml at 5% | 12.5ml | 1.25 | About 31ml |
| 250ml at 4% | 10ml | 1.0 | 25ml single |
So a 330ml can at 5% is about four-fifths of a double, in a lot more tonic. That can be exactly what you want on a hot afternoon. Just don't pay double-measure money for it. We settled on 250ml because it's one full drink that stays cold and fizzy to the last sip. At 8% it's also honestly two units, which is worth knowing before you open a second.
The pour
Whatever can you buy, do it justice. Pour it over plenty of ice in a proper glass and garnish it; for ours, a strip of orange peel. Drinking a G&T from the can is like drinking wine from the bottle. It works, but you're leaving half the drink behind, because most of what you taste is smell, and a glass gives the aroma somewhere to go. Cold matters too. A warm can poured over ice melts the ice fast, and you end up with a watery drink, so chill the can first.
Four things, and how to hold us to them
A canned G&T should be a bar-quality drink that happens to come in a can, not a compromise you accept for convenience. The label tells you whether it is. An ABV that matches a bar recipe. A named gin. A tonic you'd buy on its own. A can size that makes sense against the strength. If a can clears those four, buy it with confidence. We'd naturally suggest starting with ours, and now you know exactly how to hold us to account.
If you'd rather have a cocktail than a long drink, we make those too, bottled at 20% rather than canned at 8%. Our bottled cocktails are made differently, and we explain the difference and how to serve them.
Enjoy responsibly. Our spirits are for adults aged 18 and over. One 250ml can of ours contains 2 UK units.
