On the beer issue: lager is quite big over here but we still drink ale as well.
There are some 'real ale' snobs who won't countenance lager as an alternative. I am not among them and very much enjoy a pint of lager on a hot day (and, as the Australians say, I've never been cold in my life ...). We have even started to brew our own lager. In fact quite a lot of the 'foreign' lager served here is already brewed here under licence, but I am referring to small-scale,usually organic breweries producing specialised lagers with a more distinctive flavour.
Having said that, I do prefer a good pint of real ale. However, the idea that it should be served warm is
wrong, wrong, wrong. It was very unfortunate that this myth was reinforced by a speech given by our last Prime Minister (John Major).
What is correct is that ale is
fermented at a higher temperature than lager using a yeast that forms a thick head on top of the beer (as opposed to lager, which uses a bottom-fermenting yeast i.e. one which sinks to the bottom of the beer).
Real ale (as opposed to keg beer - another thing entirely) then undergoes a secondary fermentation in the cask, which should ideally be stored in a cold dark cellar. The beer should then be served at
cellar (not room) temperature, i.e. cool, but not cold).
Another key point is that no additional gas should be introduced, either to 'preserve' the beer in the cask or in serving it.
