On holiday I watched Monty Python’s Holy Grail for the first time in years. Unlike most of their stuff, it’s actually still very funny. Whilst watching the taunting Frenchman bit below, I had a bit of an epiphany. Elderberries were traditionally used to bolster the colour in wine. If your vintage was a little week, a load of elderberries would quickly make the wine appear much richer. Port was often bought on colour alone so eldeberries were a good way of tricking (usually British) merchants. In 1757 the Portuguese Prime Minister, The Marquis of Pombal, passed legislation that made it illegal to plant elderberry bushes within the demarcated port region. It wasn’t just in Portugal, however, these berries were commonly used by merchants in Bordeaux and London to make weedy claret look better. So perhaps the Frenchman in the Holy Grail was actually accusing King Arthur’s father, Uther Pendragon, of selling dodgy wine, a grave insult in France. No idea about the hamster thing though.
