I have noticed that the Golden Ale has been terrible for a long time, over a year. - watery, no hop aroma and that awful taste of carlton and piss.
As for the Amber ale I think it is slowly following down a similar path... its becoming more and more like a slightly darker megaswill with very little hop presence and becoming sweeter, more watery and pissy.
It seems the way good commercial brews go.... Sad but true.
I think what these breweries do is create a nice beer that appeal to both mainstream as well as those who like a good micro beer then slowly take short cuts to cut costs once they have a bit of a customer following.
