What the festival is
Britain's largest beer festival is organised by CAMRA – the Campaign for Real Ale – and held in summer each year. It is the national showcase for cask ale: beer that arrives in its living state and is served by gravity, straight from the cask. No fonts, no gas lines, no kegs behind the bar. Volunteer staff draw each pint by tilting the cask or turning a tap, and the beer that reaches your glass has been conditioned naturally inside the vessel that holds it.
Beyond the main cask bar – covering hundreds of British ales, stouts, porters, bitters and more – there are usually separate areas for cider and perry, plus international bars pouring lagers and ales from overseas. Think of it less as a pub and more as a temporary city of beer, mapped out across a large indoor venue and staffed almost entirely by volunteers.
How to navigate it as a first-timer
Third-pint measures are the standard unit. You are expected to taste widely rather than settle on one beer and stay there. A third of a pint lets you work through styles – a pale golden bitter, a dark mild, a smoked porter – without committing to a full glass each time. Half-pints and full pints are also available.
Every festival produces a printed programme listing each beer by name, brewery, style and alcohol strength. Experienced visitors mark it up before queuing. Read the strength column carefully: the range typically runs from light session ales well under four per cent to strong barley wines at twice that, and they can look identical in the glass. The programme is the map; without it, the choice is overwhelming.
Queues at popular bars move steadily because the pouring is straightforward – gravity and a steady hand. Prices are paid in tokens bought at a central point, keeping transactions fast at the bar.
Why cask presentation shapes the whole event
Cask ale is a living product. Secondary fermentation continues inside the cask after it leaves the brewery, and once a cask is tapped and opened to the air, it begins a slow, irreversible change. As covered in our cask ale article, the beer on the first day of the festival will differ from the beer on the last – not worse, necessarily, but different. A cask that was slightly cloudy on opening day may be bright and settled by day three; one at its peak mid-week may be fading by the final session.
This is not a flaw to be engineered away – it is the nature of the product, and the festival format makes it visible. Some drinkers arrive early in the week for younger, livelier pints; others wait for certain styles to condition properly. The volunteer staff, who taste throughout, will generally tell you honestly which casks are drinking well at any given moment. These are people who are there because they care about the beer, and that shows.
Champion Beer of Britain
Running alongside the public festival is the Champion Beer of Britain competition, judged by CAMRA members across a range of style categories before the overall winner is announced. The categories reflect the breadth of British brewing – bitters, milds, stouts, porters, golden ales, strong ales and more – and winning even a category medal carries real weight in the trade. The champion is usually announced during the festival week, and the winning beer often sells out within hours of the result.
For visitors, the competition adds a layer of interest to the programme: you can seek out previous category shortlists and form your own opinion before the judges deliver theirs.
Regional festivals
CAMRA runs regional beer festivals throughout the year, from small local events in pub car parks to larger city-centre gatherings that run for several days. The format is consistent – cask ale served by gravity from stillage, a printed programme, third-pint measures – even when the scale is a fraction of the national event. Many regional festivals also run their own local champion competitions.
