The Mixer Learned to Grow Without the Gin

The premium mixer was the best trade in drinks for a decade. It sold a branded, carbonated, duty-free product into an occasion that a spirits brand had spent a fortune creating, and it captured margin that the gin could not because the gin was carrying GBP 8.04 of duty a bottle. Then the gin stopped being drunk the way the mixer needed it to be drunk, and the mixer’s own accounts now show it.

Fever-Tree’s full-year results to 31 December 2025 are the only audited window into the premium-mixer trade, and they are more interesting than the headline. Brand revenue reached GBP 372.7 million, up 2 per cent reported and 4 per cent at constant currency, accelerating to +5 per cent in the second half. Adjusted EBITDA fell 16 per cent to GBP 42.4 million and the margin went from 13.7 per cent to 11.3 per cent — a 240 basis point compression on a 2 per cent revenue increase. Diluted earnings per share fell 11 per cent.

Read the geography against the gin category’s own geography and the attachment problem becomes visible. The UK — the most gin-and-tonic-shaped market on earth, and the one where the modern premium mixer was built — fell 2 per cent. The growth came from the rest of the world at 22 per cent constant currency, and from the United States at 6 per cent through a distribution transition to Molson Coors.

The gin grew where the serve doesn’t exist

Gin moved 109.0 million nine-litre cases — 981.0 million litres — and USD 14.0 billion at retail in 2025, up 1 per cent in volume and 2 per cent in value with pricing at 3. That is USD 14.27 a litre. The category’s volume is 26 per cent above 2019 while the United Kingdom is 40 per cent below its peak.

Those two facts, taken together, are the mixer’s problem. The growth is not in the G&T occasion. It is in markets where gin is sold at USD 2.53 a litre — a fifth of the world average — and drunk in ways that do not involve a branded tonic, a highball glass or an on-trade setting that can charge for both. The Philippines is the largest single volume block in the category. Africa, Russia and India are the growth markets.

A mixer’s revenue is a function of occasions, not of litres. The category can add volume for a decade in markets where the occasion never appears, and the attachment ratio falls while the gin line rises. That is what “gin is growing” and “the mixer’s UK revenue is falling” mean at the same time.

The tax asymmetry that made mixers structurally better — and smaller

There is a reason the mixer business looked so attractive, and it is fiscal. Tonic pays no spirit duty. In a gin and tonic, the entire GBP 8.04 of duty on a 70cl bottle at 37.5 per cent sits in the gin; the mixer contributes nothing to the excise line while capturing a share of the price. A branded mixer grows with the occasion and does not carry the tax that makes the occasion expensive.

That is a genuinely advantaged position, and it explains why the premium mixer could charge a premium at all. But the advantage is bounded by the size of the occasion, and the accounts show the bound being reached: 13.7 per cent EBITDA margin became 11.3 per cent in a year when revenue grew. The premium-mixer thesis was that premiumisation would migrate from the spirit to the mixer. What actually happened is that it migrated to mixer branding, not to mixer profitability.

The company’s own strategic answer confirms the diagnosis. 45 per cent of group revenue now comes from products beyond tonic — ginger beer delivering double-digit growth in Europe, ginger ale, soda, cocktail mixers. A business built on one attachment is now majority-adjacent to it. That is a rational response to a structural fact: the gin and tonic is no longer where the world’s gin is.

What the two categories are actually selling

Gin sells a differentiated drink at a low price in a duty-dominated chain. Its producer’s revenue per litre in the United States — USD 112.02 a case, USD 12.45 a litre on 8.034 million cases — is below the world’s retail price per litre. The mixer sells a branded, low-cost, duty-free input to that occasion.

Both are therefore exposed to the same thing: the occasion’s price. When a full-strength G&T carries GBP 8.04 of duty in the gin alone, the pair has a structural incentive to migrate to a lower band. And it has. A 5 per cent ready-to-drink serve pays GBP 1.33 per litre in duty against GBP 11.48 for the gin — 8.63 times less per litre — and pre-mixed formats absorb the mixer inside the taxed product rather than beside it. The most successful recent innovation in the gin occasion removes the standalone mixer from the transaction.

That is the real threat to the attachment, and it is not a branding problem. It is a packaging-and-tax problem. The mixer’s best customer was a drink that had to be assembled in front of the drinker. Every format that assembles it in a factory, or serves it at 5 per cent, or sells it in a market where tonic is not part of the serve, takes a mixer revenue line out of the chain without taking a gin litre out of the category.

Three tests to run next year

One — whether UK revenue stabilises. The UK is the purest read on the attachment: it is the market with the deepest G&T culture and the steepest gin decline. If UK revenue keeps falling while rest-of-world grows at 22 per cent, the mixer is diversifying away from the occasion, not defending it.

Two — whether margin recovers before revenue does. An 11.3 per cent EBITDA margin on a premium brand is thin. A buyback — GBP 100 million completed, GBP 30 million more in progress, funded from operating cash flow — is a sensible use of that cash, but it is also what a company does when it does not have a growth investment to make.

Three — whether the mixer follows the gin into the low band. The tell would be a branded 5 per cent serve carrying a mixer’s name rather than a spirit’s. That is the only route by which the mixer keeps the occasion after the occasion has left full strength.

What this does not show

Fever-Tree is one company, and it is not the mixer market. It is, however, the only listed pure-play with audited accounts in it, so it is the only place where a claim about mixers can be checked against a filing rather than a press release. The category-level statement that can be defended is narrower than the company-level one: the premium mixer’s growth was tied to a specific occasion in specific markets, that occasion is not where the world’s gin volume is growing, and the mixer’s own disclosed numbers now show it repositioning around that fact.

Gin’s forecast is USD 18.01 billion by 2033 at 3.20 per cent on volume growing 1.10 per cent — a price-and-mix forecast built on a category total. Nothing in it depends on the tonic attachment holding. The mixer’s revenue does, and that is the difference between the two businesses.
