I'll do this phonetically: Portugal, Oporto, Port. Get it? Port comes from Portugal! We had a fantastic guide, George, who led us through Graham's portery, er, winery. I learned all about port, but have now forgotten most of it. Is the sweetest port the middle aged port? I think so.
True story: I bought a bottle of Port to bring home to my son and his wife. On my way home, going through customs in Amsterdam, I was asked if I had any alcohol. I replied that I had a bottle of Port. I was only 1 of 2 people on the entire flight who had to have a baggage search, even of my checked luggage, as they looked for the Pork in
my luggage. Someone finally realized that I had Port not Pork.
