But back to topic. It all depends on alcohol percentage and live bacteria in the beer. Normal beer (in the 4 to 6% alc. range) lasts about 8 months, depending on the brand. Higher alcoholic beers (like the 12.8 % Cannon from Grolsch) stay clean for about a year.
But the 'spoiling'of the product that the producers base the final consume-date on is that the bacteria in it alter the alcohol percentage upwards. It can still be consumed even if the conservation-date has expired, without ill effects. As alcohol is a preserving substance, beer has a natural defence against bugs.
Beer only really spoils and becomes bad many months after it was bottled; talking 1 and a half year later, even 2 years in case of the heavy beers.
Yes. What matters is the yeast-bacteria. These produce alcohol out of sugars in both beer and wine. When making beer, the product is bottled when it reaches the desired percentage, including the live bacteria.
But when yeast causes a alcohol percentage of over 13%, they die because of their own product, as they can't stand it in those quantities.
And that is what happens when making wine, the yeast does not survive to see the bottle.
So in beer they are still alive and can influence the drink by living (processing and crapping) in it, while they are not present alive in wine, causing no trouble.
