Cheers to Beer

 I've only just realised, with a start, that today is National Beer Day.
 The date was chosen because it's the anniversary of the signing of Magna Carta, which has something to say about standard measures of beer and other drinks – and also, one would like to think, represents our traditional liberties, of which the drinking of beer, preferably in a pub, is a pretty good embodiment. Johnson was a great advocate of what we now call the pub: 'There is nothing which has yet been contrived by man, by which so much happiness is produced as by a good tavern or inn.' I think he would have loved Wetherspoon's, that most convivial of national institutions – and famed for its cheap, well kept beer. 
  National Beer Day enjoins us to raise a glass at 7pm in a national Cheers to Beer toast. I'll drink to that.
