And there's the centre of it.
Cloudy beer is almost always due to yeast, in my experience. Rarely have I tasted a cloudy beer with a clean refreshing flavour where the cloudiness was due to hops.
Yeast, to my palate, gives the beer a rough, tart and unpleasant bitter taste. From a brewer's point of view, though, it makes life easy. Don't bother cooling at the end of fermentation, don't add any finings, don't give the publican any training in serving the beer.
A micropub local to me has the decency to write on the blackboard which beers are fined and which aren't. They tell me the unfined beers always clear towards the end of the barrel. Has to be yeast, therefore. I want to drink beer, not yeast soup!
