well, king of portman rd, i think we can agree that both counties produce great ales, as i like adnams but would prefer broadside, the standard bitter and lighthouse to the ones you mention. also Ghost ship, which is new, is very good
although suffolk has two major brewers in greene king and adnams, there are many small breweries in norfolk that produce good ale, which means it's not distributed nationally. Wolf springs to mind. also woodfordes. Both norfolk and suffolk ales are better than the ones round my way.
My other point is not all of Greene King is Suffolk beer now, as they have bought up many smaller breweries in recent years. Moorlands of oxfordshire is a good example, so old speckled hen is brewed in Bury now. I'm not saying it's a bad thing, just that the origins are not suffolk.
Cheers everyone
