Madeira Terrantez wines are traditional fortified Madeira wines from the eponymous Portuguese island made, in theory at least, using mostly Terrantez grapes. The category has all but disappeared today, as the island's plantings of the variety have declined significantly in the last century, and there are hardly any left. However, Madeira Terrantez is so long-lived that there are still a number of wines on the market that were made in the 18th and 19th centuries.
