British beer strength dropping as brewers dilute drinks to beat taxes

British beer is getting weaker, according to a new study. Researchers report that since 2022, the average strength of both canned beer and bottled wine has slipped by roughly one per cent. This subtle shift comes with a stark reality: there has been a sharp surge in sales for beers containing less than 3.5 per cent alcohol.

To put this drop in perspective, it equates to an additional 14.2 million pints of alcohol being consumed across the UK by the end of last year. While five times more low-strength beer is now being drunk, experts warn that this trend isn't solely driven by Brits choosing to drink less.

The University of Sheffield team behind the research points a finger at new duty laws. These regulations effectively encourage brewers to dilute their products to qualify for lower tax rates. By analyzing six million purchase records from 30,000 families, the study sought to understand how these legislative shifts altered consumer behavior.

Before the tax and duty overhaul, the average alcohol content across all drinks hovered between 17.2 and 17.7 per cent. Following the changes, that figure fell to 16.6 per cent by last year's end. Specific breakdowns show beer strength dipping from 4.5 per cent in 2022 to 4.4 per cent recently, while wine dropped from 12.6 to 12.3 per cent and spirits slipped slightly from 36.5 to 36.2 per cent over the same period.

The market for weaker beer has exploded. Previously, only three per cent of Britain's beer consumption was below 3.5 per cent; now, that figure has climbed to 18.1 per cent—nearly one-fifth of the entire market. The researchers highlight that these shifts carry 'clear implications for public health.' Alcohol remains a leading cause of illness and premature death, with over 10,000 deaths linked to alcohol in 2023 alone—the highest recorded figure.

Professor Colin Angus, who led the study, noted the findings reveal a 'clear appetite' for lower-strength options. He explained that experimental evidence suggests people tend to consume less total alcohol when drinking weaker beverages. Under optimistic assumptions, the drop in product strength could have reduced average consumption by 2.7 per cent since 2022.

However, caution is warranted. Even with this significant change in drink formulation, alcohol-specific deaths remain approximately 25 per cent higher than they were in 2019. Professor Angus warned that reformulation alone cannot solve the high rates of harm currently plaguing communities. The study, published in Drug and Alcohol Review, admitted certainty about a direct causal link between the 2022 duty changes and weaker drinks is elusive. Still, they found that one in every twenty alcoholic beverages has been reformed recently to contain less alcohol.

The timing speaks volumes: the strong association between the reforms and the spike in reformulation activity strongly suggests the policy changes played at least a partial role in driving this trend. As duty structures continue to evolve, the composition of our nation's favorite drinks will likely follow suit, leaving communities with more diluted options but not necessarily better health outcomes.
