Real ales, stouts, and lagers are living beers. They are either conditioned in a bottle or a cask (barrel). Cask beers have a short shelf-life. Bottled beers can live for a long time.
Dead beers are sold in kegs and bottles. "Dead" means that fermentation is stopped by the addition of SO2 (Sulphur {US= Sulfur} Dioxide). The beer is then kept under pressure of CO2 (Carbon Dioxide) and is chilled. Guinness for long distance storage is pressurised by Nitrogen so it does not get over fizzy.
Now call me old fashioned but I prefer a living beer. I hate chemical beer like "Eurofizz" or US Budweiser. Real Budweiser from the Czech Republic is a living beer. UK beers are either living or dead. I prefer real ale. Guinness has achieved a good half-way compromise when it is shipped a long way. It is dead but held in a zombie state. Guinness in Ireland is outstanding. Guinness in the US is better than anything but Bass.
Ah, Bass ... there is another tale. Bass comes from Burton-upon-Trent which has the best water in the world for making beer. Why do I say that? Because every other brewery uses a process called Burtonisation where they change their water to be like the river Trent in Burton.
Even Guinness with the Liffey as its source Burtonises the water.
Who cares ... time for a pint.
