A pub trip around Britain for cask ale lovers

What cask ale is

Cask ale, often called real ale, is beer that leaves the brewery unfiltered and unpasteurised with some live yeast. It finishes conditioning in the cask in the pub cellar, building gentle natural carbonation. It is then served without added gas, usually drawn up by a hand pump called a beer engine.

The result is softer and less fizzy than keg beer, served at cellar temperature, around 11 to 13 °C. That is cool, not cold. It lets malt and hop flavours show. Our guide to real ale and how it differs from keg beer goes into the detail.

Why the pub matters as much as the brewery

Cask ale is fragile. Once a cask is tapped, air comes in as beer goes out. Most cellar managers aim to sell a cask within about three days before it starts to go flat and stale. Temperature, cleaning of the lines and how long the cask rested before tapping all change what reaches your glass.

So the same beer can taste excellent in one pub and tired in the next. A good cask pub is one with a cellar manager who knows their job and enough trade to turn casks over quickly.

Reading the pump clip and the glass

The pump clip on the hand pump is your menu. It shows the beer name, brewery and ABV. Many add a short description. A clip turned around or covered usually means the cask has run out or is settling in the cellar.

Look at the beer before you drink. Most cask ale should be bright and clear, since the yeast drops out in the cask. A hazy pint in a style that should be clear can mean the cask was tapped too early or disturbed. Some modern cask beers are hazy on purpose, so ask if you are unsure. A good pub will happily change a pint that tastes wrong.

Finding pubs that keep it well

Two resources help. CAMRA, the Campaign for Real Ale, was founded in 1971 to protect cask beer. It publishes the annual Good Beer Guide, which lists pubs chosen by local volunteers. Many pubs also display Cask Marque plaques, a scheme that checks the temperature and quality of cask beer.

Beyond that, trust your eyes. A busy pub with several hand pumps, clean glasses and staff who can tell you about each beer is usually a safe bet. A quiet pub with eight hand pumps may be struggling to sell them fresh.

How to order at the bar

In most British pubs you order and pay at the bar, then take your drink to a table. There is no table service in a traditional pub and no tipping is expected for a drink at the bar.

• A pint is 568 ml. A half pint is the polite way to try more beers.
• Ask for a taste if you are unsure. Many bars will offer a small sample.
• Read the pump clip on the hand pump for the beer name, brewery and ABV.

Many cask ales sit between 3.5 and 4.5% ABV, lower than most craft beer in India. That makes them good for a long session, but halves still add up.

Styles worth tasting

A first trip should cover the classic British cask styles:

• Bitter and best bitter: amber, malty, with earthy English hops.
• Mild: dark, low strength, soft and malty.
• Golden ale: pale, light and hop-forward.
• Porter and stout: roasty and dark.

Regional differences are real. Northern pubs often serve beer through a sparkler on the nozzle, which gives a tight creamy head. Southern pubs often do not. Try both and notice how the head changes the bitterness.

Trains, rounds and pacing yourself

Britain's trains connect most cities and many market towns, which suits a pub trip. A few days in London, then a city in the north and a historic brewing town makes a good first circuit. Burton upon Trent was the centre of English pale ale brewing in the nineteenth century and is easy to reach by train.

Indian travellers need a UK visa, so apply early. Book trains ahead for cheaper fares and check the last train back before settling into a long evening.

Pubs are social places and rounds are a custom: one person buys a drink for everyone, then the next person takes a turn. Rounds make pacing hard. It is fine to buy your own drinks or switch to halves or soft drinks. Nobody minds.

Eat. Many pubs serve food at lunch and in the evening. Drink water between pints. Do not drive. British drink-driving limits are strict and enforced.

Taste the condition

Cask ale teaches you to taste condition: the level of carbonation, the temperature and the freshness of the beer. A cask at its best tastes lively and clean. One past its best tastes flat, sour or of vinegar. Learning to tell them apart is a sensory skill worth having, whatever beer you drink.

Your first step: get a copy of the Good Beer Guide or its app and pick three highly rated pubs in the first city you plan to visit.

Common questions

What temperature is cask ale served at?

Usually at cellar temperature, around 11 to 13 °C. That is cool rather than cold, so malt and hop flavours come through.

Do you tip in British pubs?

Tipping is not expected for drinks bought at the bar. For table service meals, a tip is common if no service charge has been added.

What is a beer engine?

A beer engine is a hand pump that draws cask ale up from the cellar without added gas. It is the classic way to serve real ale.
