The Cost of Drinkflation: Beer Alcohol Levels Lowered to Cut Taxes

By the Editorial Team · Thursday, July 30, 2026

Several major UK beer brands, including Carling and Foster’s, are lowering their alcohol content to benefit from reduced taxes under the 2023 alcohol duty system. This strategy helps brewers cut costs without lowering retail prices, while tapping into growing consumer demand for lower-alcohol beverages amid rising “drinkflation.”

Several popular beer brands are reducing their alcohol content in response to changes in the United Kingdom’s alcohol duty system introduced in 2023, a move that allows them to lower tax liabilities while maintaining retail prices. Carling Original, for example, will see its alcohol by volume (ABV) drop from 4.0% to 3.4% starting in October 2026. This policy shift is part of a broader trend, with other well-known beers having already reduced their strengths in recent years.

Under the revised tax framework, beers with an ABV between 3.5% and 8.4% face a duty rate of £22.58 per litre of pure alcohol, while those below 3.5% are taxed at £9.96 per litre. Reducing a beer’s ABV to just below the 3.5% threshold can significantly cut the amount of duty payable. For example, a 4.0% beer incurs about 41p of duty per pint, but a 3.4% beer pays approximately 19p per pint. This creates a strong incentive for brewers to weaken their products to reduce tax costs.

Several other brands have followed a similar path. Foster’s, once at 4.0% ABV, lowered its alcohol content to 3.4% earlier this year. Sol was reduced from 4.2% to 3.4% in 2025. Carlsberg, Grolsch, John Smith’s, Coors, and Amstel have also lowered their ABVs over recent years, typically settling around 3.4%.

Brewers emphasize that the adjustments are supported by consumer testing aimed at maintaining taste quality. Molson Coors, the owner of Carling and Coors Light, said that consumer feedback indicated a preference for the lower-strength versions while assuring customers that the signature taste remains balanced and refreshing. Heineken, which owns Foster’s and Sol, similarly stressed its commitment to quality, citing extensive recipe development to preserve the flavor experience despite strength reductions.

Industry representatives also point to the growing market for lower and no-alcohol beers, attributed in part to the tax structure and broader health-conscious trends. The British Beer and Pub Association noted a significant rise in sales of low-alcohol products, which now comprise 12% of the market, and a historic increase in no- and low-alcohol beer sales since 2013.

Despite alcohol content reductions, beer prices have not decreased, contributing to what has been described as “drinkflation.” The average cost of a pint of premium lager is reported to be £5.92, with some specialty brands selling for notably more. Prices vary by region, with London typically seeing the highest costs for popular craft and premium beers.

A spokesperson for HM Treasury defended the revised alcohol duty regime, highlighting its intention to support pubs by offering tax relief on pints served in establishments while incentivizing the consumption of lower-alcohol products as part of public health objectives.

Overall, the industry adjustment reflects an effort to adapt to tax policies that place a heavier financial burden on higher-strength beers. While some consumers may notice weaker beers, producers argue that taste and quality remain key priorities amid these changes.
