A Pint of Plain Is Yer Only Man
"A pint of plain is yer only man" - Flann O'Brien, Ireland's greatest writer.
2009 is the 250th anniversary of Guinness. Like wines, if you want to sample the authentic flavour then you must visit Ireland, especially parts west.
A creamy head of Guinness (at about room temperature) served in a quiet pub on the Atlantic coast while having a dozen oysters is something to be experienced.
