Wine/American portwine


Hello Paul Wagner!

Just saw your answer about Prager Port and I wondered how they can call it "Port"? I thought it was restricted to wine made in the Duoro Valley in Portugal (Oporto)?

Or do they call it - like Spanish Cava: Made by the Champagne method - "Made by the port method"?

all the best


Hi Rene

It's a long story.  The original treaty to protect such names was signed right after World War I, and the US was in the middle of Prohibition.  Since commercial alcohol production was illegal in the USA, we didn't both to sign treaty.

Over the years, such names have become commonly accepted here in the US, and actually defended in court with some very misguided regulations.  

We are now moving in the right direction, but some producers are still handing on to the old terms, and seemingly don't care about either international law or their own ethics.
