My local (in Yorkshire) looks after it meticulously, and it still isn't the same beer it was 3 years or so ago. It doesn't taste the same, and it doesn't behave the same way in the cellar. My guess is that it's undergone a fundamental change in the brewing process (which may or may not be connected with the increase in production recently).
It's still a good pint, just not the same beer. Shame.
