It's a bit controversial on here I think and Some people would call me a beer snob.
It's been mentioned in other threads but here's my thoughts.
A beer served from a hand pull has no C02 added either for carbonation or serving. It is naturally carbonated "real ale" It needs care to look after, has been brewed in traditional methods. Needs to be consumed in a short period of time.
This for me is real cask ale. A cask can be plastic, metal and very rarely wood.
Beer served from taps uses CO2 to force the beer through the tap, it is usually force CO2 carbonated. It can be anything. I guess there are good beers from these and I would drink them on recommendation.
I'm not saying all cask beer served from pumps is better than beer from taps but if the Pump is available then that's what I'll drink.......
You can get crap fillet steak and good burgers, but if you go for the fillet steak your more likely to no get crap.
I've never experienced a bar that serves 100's of styles of beer and they must be better than the ones that only offer a few but I would question whether they have the same quality has the place with 6 hand pumps where the cask has gone within a day or so so there is always fresh stuff on.
As for the Fullers then that would be seen as the Top end of bitters from a Pull. I loove the fullers range and drink it at the bar and from the bottle.
Bitters that you get on Tap would Be Like Tetley's, Boddingtons, all sorts.
They are like the Bud of the pilsner world.
Mass produced, thin pasteurised dead beer that Is then regassed at the place of dispensing. Lots of people like them and drink them. They are not bad just not the "real thing"
