I had all four yesterday as a trial run. Couldn't detect any real difference between Murphy's and Guinness, despite drinking them in direct comparison (mouthful from one, mouthful from the other). Beamish seemed to have an entirely different hop character to it, and O'Hara's tasted of real beer <!-- s:) --><img src="{SMILIES_PATH}/icon_smile.gif" alt="

No way I'm going to be able to ID them, but it should be fun anyway <!-- s:D --><img src="{SMILIES_PATH}/icon_biggrin.gif" alt="
