The can affects flavour (slight metal taste)
Some beers are "bottle conditioned" so are still fermenting in the bottle to get the right taste.
Even how a pint is pulled affects the flavour, to do with bubbles etc, and also how it's looked after from brewery to pump.

No it fucking doesn't
You pull the pump, the beer comes out, you drink it. If the pub doesn't clean the lines then you can get a load of manky rnacid beer in with your nice beer which ruins it, but the action of pouring has no fucking effect at all. And none of if tastes "peaty"

No, it's becasue the only beers that are electric pumped are shit ones like "John Smiths" and "Tetleys"

This is true, however they are also available hand pumped
which makes them passable in the absence of anything better.
Food and drink companies devote a lot of money and research into how bubbles and foams affect taste and texture. Particularly in the case of cakes!

This is boring me.
And I spent 3 hours at the weekend reading about the temperatures different hops break down.
