From the latest edition of Clare News, the magazine for alumni of my Cambridge college:

When the Archbishop of York met Pope Benedict XVI in Rome recently, he gave him an unusual gift …: a special, one-off beer called ‘Holy Grail’ …

For a fuller version of this story see this page on the brewery’s website, which also has a picture of the beer bottle, and its full name:

MONTY PYTHON’S HOLY GRAIL Tempered with burning witches

– with the “GR” crossed out.

Clare College has a strong theological tradition, numbering among its past members Prof Charlie Moule and Archbishop Rowan Williams. But in this case the link with the college is not the Archbishop, nor the Pope, but the head brewer.
