Portugal is home to one of the greatest international wine success stories of modern times. That is the production and marketing of medium sweet, lightly sparking rosés. In the late 1980s, Mateus accounted for over 40% of the country's total table wine exports and was especially popular in Europe. Lancers is better known in the United States, where it continues to be successful.
