Beer duty
Excise tax on beer, charged in most jurisdictions by reference to alcoholic strength and volume, with reduced rates for small producers.
Also called excise duty, small brewers relief, small producer relief.
Legal. Fixed in law, and only in the places named. It may differ elsewhere and change over time. Defined by National tax authorities. As recorded here it applies in United Kingdom.
Duty shapes what gets brewed far more than most drinkers realise. Where rates step at particular strengths, products cluster just beneath the step — which is much of why British session beers sit at the strengths they do, and why so many low-alcohol products land just under 1.2%.
Small producer reliefs, and the rate at which they taper as a brewery grows, have been a live policy argument in Britain for two decades because of the incentives they create around expansion.
Rates and structures change with each budget. BeerHQ records that duty is strength-banded rather than quoting figures that would be stale within a year.

Evidence
What BeerHQ knows about this, and how. Every statement carries the state of the evidence behind it rather than being presented flatly as fact.
United Kingdom beer duty is charged per litre of pure alcohol within strength bands rather than on the finished volume, with a reduced rate for small producers — and because the band boundaries fall at 1.2%, 3.4% and 8.4% ABV, they visibly shape the strengths at which British beer is formulated.

Small Brewers’ Relief, introduced in the United Kingdom in 2002, reduced duty for low-volume producers and is widely credited with the subsequent expansion in the number of British breweries. It was replaced by Small Producer Relief under the 2023 alcohol duty reform.

Small Brewers’ Relief was widened two years after it began: from 1 June 2004 the production ceiling for the reduced rate rose from 30,000 to 60,000 hectolitres a year, with a tapered rate between the two.
