Yes, Pope Benedict drinks Reverend James bitter! The above picture shows him when he was Cardinal Ratzinger (but a mole in the Vatican informs me that a draycart (beer delivery truck) makes a weekly call to the Vatican and drops off a keg of the ambrosial brew). So, now the Pope drinks Rev James bitter!
Now I can honestly* claim that the Holy Father and I share the same taste in good ale** - Amazing.
