which beer is the best in the world?

Anyone?

Serving drinks at arctic temperatures is a comparatively recent phenomenon introduced by a drinks industry whose promotion policy is gimmick-based. Cask ales should be served at around 55 degrees F (not exactly warm), whereas keg beers and lagers are typically served some 10 degrees F lower and “extra cold” beers even less. There can be no taste reason why this should be, since chilling tends to mask subtle flavours but since keg beers don’t have any, it can only be that those who choose them aren’t much bothered about taste anyway.

Temperature[edit]
One common misconception of beer served in the United Kingdom concerns the serving temperature: it is believed that British beer is served warm. In reality, beer in the UK is usually served at cellar temperature (between 10–14 °C (50–57 °F),[citation needed] which is often carefully controlled in a modern-day pub, although the temperature can naturally fluctuate with the seasons. Proponents of British beer say that it relies on subtler flavours than that of other nations, and these are brought out by serving it at a temperature that would make other beers seem harsh. Where harsher flavours do exist in beer (most notably in those brewed in Yorkshire), these are traditionally mitigated by serving the beer through a hand pump fitted with a sparkler, a device that mixes air with the beer, oxidising it slightly and softening the flavour.[citation needed]
