Gin's Real Competitor Is the 5 Per Cent Band

Ask a drinks executive which category gin competes with and the answer will be vodka, or occasionally rum. The tax code gives a different answer, and the tax code is the one the launches follow.

UK spirit duty is charged per litre of pure alcohol, in bands that step at alcohol strength. In the band a full-strength gin occupies — 8.5 to 22 per cent — the rate from 1 February 2026 is GBP 30.62 per litre of pure alcohol. On a 37.5 per cent gin that is GBP 11.48 of duty per litre of finished drink. In the 3.5 to 8.4 per cent band the rate is GBP 26.61, which on a 5 per cent ready-to-drink serve is GBP 1.33 per litre.

Same alcohol, 8.63 times less duty per litre of product, and 13.1 per cent less per unit of alcohol. That is not a rounding difference. It is a design instruction, and the industry has spent three years following it.

The launches moved to where the tax is

Diageo launched a Gordon’s Spritz Edition in 2025 — Strawberry & Passionfruit and Lime & Elderberry — explicitly designed to be drunk with Prosecco, off the back of the world’s largest gin brand losing 0.5 million nine-litre cases in a year. Pernod Ricard answered a 1.2 per cent fall on Beefeater with grapefruit and alcohol-free variants. Portfolios filled with spritz editions, hard seltzer formats and 5 per cent serves.

None of that is a coincidence of taste. A 5 per cent serve pays GBP 1.33 of duty per litre against GBP 11.48 for the same brand at 37.5 per cent. Draught product in the 3.5 to under 8.5 per cent range attracts GBP 19.45 per litre of pure alcohol, the cheapest route to a drinker in the entire schedule. Reformulating into a lower band is worth more per litre than any botanical innovation available to the same company, and it needs no new plant. The tax code, not the palate, has been directing product development.

The one place the code points the other way is strength within the spirits band: a 43 per cent navy-strength gin pays GBP 9.22 per 70cl bottle against GBP 8.04 at 37.5 per cent — 14.7 per cent more duty for the same bottle. Higher strength is now a marketing claim a producer pays for annually. That is the only part of the category where the price of a positioning is fully visible on the label.

Flavoured gin is the cautionary case, not the success case

Flavoured gin drove the last leg of the UK boom at near-zero marginal cost — a new flavour is a recipe, not a plant — and then fell from a third of UK gin consumption to a fifth, with non-flavoured gin returning to its pre-2019 trend line.

That is the cleanest evidence in the beverage sector that product innovation without process innovation produces no durable margin. The flavour can be copied within a quarter, the drinker who came for it moves on within two years, and the trade’s answer in 2025 was more of the same: grapefruit, spritz, alcohol-free line extensions. Portfolio breadth substituting for a technical advantage nobody has.

Flavoured vodka’s contraction, where it happened, is the same story one band down. The boundary between the categories was never sensory — gin is a flavoured spirit by definition, and the EU standard permits cold compounding with no still at all. The boundary is the price you can charge for a flavoured 37.5 per cent liquid versus a flavoured 5 per cent one, and the duty difference is 8.63 times per litre.

And the RTD is the only thing that grew

The market evidence runs in exactly the direction the tax code points. In 2025 total beverage alcohol volumes fell 2 per cent — 500 million nine-litre cases — the third consecutive annual decline, with beer, wine and spirits all contracting. The IWSR puts ready-to-drink as the only major category to grow, at 3 per cent, with premium-and-above RTD volumes up more than 15 per cent. Wine volumes fell below spirits for the first time.

Two details matter more than the headline. The US — about 40 per cent of global RTD volume — had its first annual decline since 2015, so the growth is now coming from outside the market that invented the format. And the premium tier of RTDs is growing five times faster than the category, which tells you that the format has stopped being a discount vehicle.

Set that against gin’s own numbers. Gin moved 109.0 million nine-litre cases in 2025, up 1 per cent in volume, and USD 14.0 billion, up 2 per cent in value, with pricing adding 3 per cent. Those three numbers do not reconcile: if price added 3 points and value added 2, then mix subtracted roughly 2. The category is selling more litres of cheaper liquid, which is the same mechanism as a spritz edition, one step further down.

Gin’s forecast of USD 18.01 billion by 2033 at 3.20 per cent on volume growing 1.10 per cent is therefore a price-and-mix forecast rather than a demand forecast. That is a defensible position, but it carries a specific risk: the leakage does not happen inside the gin series. It happens in the 3.5 to 8.4 per cent band, where the same brand, the same botanicals and the same drinker are taxed at 8.63 times less per litre of product.

The other edge of the same boundary

There is a second frontier where the boundary is chemical rather than fiscal, and it is the one product problem in the category genuinely worth solving: a credible 0.0 per cent gin.

The difficulty is specific to the product. The terpenes that carry juniper and citrus are the most volatile fraction of the distillate and the first lost in vacuum distillation, membrane filtration or any other de-alcoholisation route. That is why alcohol-free “gin” tends to taste of the absence of the botanical rather than of the botanical, and why the category’s own attempts have been line extensions — Pernod Ricard’s alcohol-free Beefeater variants, Diageo’s alcohol-free Gordon’s — rather than new products.

No verified volume series exists for alcohol-free spirits anywhere, so this report forecasts none of it. But it sits in the fastest-growing part of the sector, and it is the one place where a producer who solves a process problem, rather than a recipe problem, would own a category instead of a SKU. That is what flavoured gin could not do.

What to watch

The substitution shows up in one place before it shows up in the gin numbers: the strength mix of a brand’s own launches. A portfolio that adds 5 per cent serves while its 37.5 per cent core declines is not diversifying — it is migrating to the cheaper tax band with the same trademark.

Watch three things. Whether the premium-and-above RTD tier keeps growing at 15 per cent while total beverage alcohol falls; whether the UK’s strength bands are rebalanced in a Budget, which would move the boundary overnight; and whether any large brand launches a full-strength flavoured gin and holds it, because that would mean the parameter had shifted back.

Until then, the honest statement is that gin’s real competitor is not vodka. It is the same drink at 5 per cent, and the difference between them is a tax schedule.
