Since 1840 when Fonseca's first released a vintage Port, to the superb declared vintages of the last decade, this house has produced a succession of highly acclaimed wines even in the most adverse moments of history. Their consistency derives not only from continuity of family involvement, and the knowledge and skill passed down from one generation to the next, but also a close link with the vineyard. The firm's three estates of Cruzeiro, Panascal and Santo António are the heart of the distinctive character of Fonseca's Vintage Ports. Fonseca's respect for the vineyard and the unique environment of the Douro Valley expresses itself in the firm's leadership in the field of sustainable and organic viticulture. It was the first house to offer a Port made entirely from organically produced grapes. However, for many wine enthusiasts around the world Fonseca is best known as the producer of Bin No.27. This fine reserve Ruby Port, launched four decades ago, is one of the most popular and successful Port blends. Sharing the heritage of the great Fonseca Vintage ports, it displays the opulent fruity character which defines the Fonseca house style.
