Top 10 gassiest beers revealed

3rd October, 2017 by Rupert Millar

A study of 31 popular and readily available beer brands in the UK has revealed which are most likely to leave you feeling particularly gassy.

The research was sponsored by discount voucher website, vouchercloud, and the tests undertaken by food scientist Dr Stuart Farrimond.

Farrimond took 31 “popular” beers – including Budweiser, Stella Artois, Peroni, Pilsner Urquell, BrewDog and Corona – that could all be purchased at a “leading” UK supermarket and tested each of them at a temperature of 21° centigrade – far from an ideal drinking temperature of course but better to measure the carbon dioxide present in each.

To do so, a gauge fitted with a lid-piercing adaptor was used, the needle being able to slide into the container and take a reading while a rubber ferrule formed a tight seal to ensure no gas escaped.

As CO2 molecules are smaller than water molecules, an average single pint of liquid (or beer in this case) can hold as much as 2.1 pints of CO2 within it.

In the event it was found, perhaps unsurprisingly, that the ‘King of Beers’, Budweiser, was the gassiest beer of those tested with 2.7 pints of CO2 per pint of beer.

Stella Artois and Coors Light shared second place with 2.5 pints of gas per pint of beer while, also unsurprisingly, the ales and stouts scored much lower with Hobgoblin in fact being the least gaseous of the 31 brands tested – just 1.7 pints of CO2 per pint of beer.

Somewhat more interestingly, three non-alcoholic beers that were tested, Beck’s Blue, San Miguel 0,0% and Heineken’s 0.0, were found to be very low down on the scale with under two pints of CO2 each.

This is despite many customers apparently thinking that non-alcoholic beers are gassier than their ‘full-fat’ counterparts.

Farrimond wondered if the occasional side effects of beer drinking – a bloated feeling and belching – were simply more noticeable and less agreeable to people when sober.

An additional ‘taste test’ also found that actual carbonation levels did not necessarily equate to how drinkers perceived effervescence in their beer.

When rated in this instance the top three beers were felt to be: Kronenbourg 1664, Bud Light and Estrella Damm, even though the Kronenbourg and Estrella had rather average CO2 readings of under 2.2 pints of gas per liquid pint.

As Farrimond pointed out, lower temperatures and stronger flavour can go a long way to mask a beer’s true fizziness.
