I remember arriving in Berlin after a long overland journey (in 1971, so travel wasn't particularly easy)and my host, a lovely lady, saying that she knew I would be ready for a nice cup of tea. I sank into a chair, thanking all the Gods for smiling upon me, while she poured. Horror of horror, it was green, and cold. I'd never heard of mint tea. I nearly cried. I reckon tea should be the colour of a nice Scotch whiskey, although whiskey the colour of tea is even better.
