D’Oliveira is one of the greatest of the classic Madeira shippers, and one of the few to survive from the pre-phylloxera era. Founded in 1850, and an amalgamation of firms dating back to 1820, it is today housed in cellars that date from 1619. This small jewel of a company has always be owned by the D’Oliviera family, who were once highly important growers in the parish of São Martinho. Its stocks of old wines have grown over time, either through marriage with other wine-producing families, or by the purchase of other old firms. But the foundation for its unparalleled library of ancient vintages was laid by wines made by the family itself, from its legendary vineyards in São Martinho.
