Where to Watch Champagne Charlie (1989)

This is the story of the Charles Heidsieck who opened the market for Champagne sales in America just prior to the American Civil War. He is a reluctant French spy and is captured and spends time in a Union prison. There are two parallel love stories (he is French) and some battles with his uncle for control of the family vineyard (because his father married his mother who the uncle also loved).
