At the recent Somerset CAMRA Real Ale Festival there were a selection of un-fined beers brewed by the Moor Beer Company.
Out of interest I tasted both a fined and un-fined version of their Southern Star. They were two completely different beers, with the un-fined version being far superior (in my opinion) in taste, albeit slightly hazy.
Nicholson's pubs are stocking some un-fined brews by Moor Beer Co. If you come across them, let me know if you agree.
