Fancy a cold one? How London Pride, Brewdog Punk IPA and Heineken beers stay chilled the longest after being taken out of the fridge but Guinness gets warmer faster
- London Pride warmed by 2.9C in an hour, followed by Doom Bar at 3.1C
- Brewdog’s Punk IPA also warmed by 3.1C, but a Jaipur increased by 5.2C
- Guinness increased in temperature by 5.1C, and Carling by 4.9C
- Research done by physicist Helen Czerski, University College London researcher
Many of us regularly look forward to an ice cold beer in the garden or at the pub.
But your choice of beer is crucial because some brands warm up faster than others, according to new research.
London Pride, Punk IPA and Heineken warmed up the most slowly out of the range tested by physicist Helen Czerski – while Guinness and Carling warmed the quickest.

Ms Czerski cooled the range of beers – from Ale through to lager – to 14C and then used a thermal imaging camera to analyse the rise in temperature over an hour, the Daily Star reported.
The beers were cooled before being poured into a standard pint glass.
For those who prefer a pale ale, Brewdog’s Punk IPA is the best bet, which only increased 3.1C, but a Jaipur rose by 5.2C.

For stout and ale, London Pride came out on top at 2.9C, followed by Doom Bar at 3.1C.
However, Guinness fans will need to drink quickly because the drink warmed up by 5.1C over the course of an hour.
And Heineken lager warmed by just 3.3C, while Carling warmed by 4.9C.
Ms Czerski, who is a physicist at University College London, explained that while the bubbles, foam and colour of a beer might just feel like small differences, they have a ‘direct influence’ on how quickly they warm up.
She said: ‘As bubbles rise through any beer, they’ll drag the surrounding liquid up with them.
‘Then when the bubbles get to the top, the liquid has to go back downwards in another part of the glass.
‘These flows act to mix the drink, and it could affect the speed of warming.’

That is the reason why Guinness, with its large, frothy head, warms up more quickly – because the the flows of bubbles are mixing the drink constantly.
Ms Czerski, who used a FLIR T1K HD thermal imaging camera for the research, said the more that beer is brought to the side of the glass, the more of an ‘opportunity’ there is for it to warm’.
But she did add that the effect of peoples’ warm hands was not measured in the test, which she said could be the ‘biggest factor’.
