the great quantities of Madeira he consumed while a Massachusetts delegate to the Continental Congress. A bottle of Madeira was used by visiting Captain James Sever to christen in 1797. Chief Justice John Marshall was also known to appreciate Madeira, as were his cohorts on the early U.S. Supreme Court. Madeira and walnuts were often served together as a last course at dinner parties in Washington in the early decades of the 1800s. Modern era (19th century – present) The mid-19th century ushered an end to the industry's prosperity. First came the 1851 discovery of powdery mildew, which severely reduced production over the next three years. Just as the industry was recovering through the use of the copper-based Bordeaux mixture fungicide, the phylloxera epidemic that had plagued France and other European wine regions reached the island. By the end of the 19th century, most of the island's vineyards had been uprooted, and many were converted to sugar cane production. The majority of the vineyards that did replant chose to use American vine varieties, such as Vitis labrusca, Vitis riparia and Vitis rupestris or hybrid grape varieties rather than replant with the Vitis vinifera varieties that were previously grown. By the turn of the 20th century, sales started to slowly return to normal, until the industry was rocked again by the Russian Civil War and American Prohibition, which closed off two of Madeira's biggest markets. After the repeal of Prohibition, improved shipping technology meant that ships no longer needed to stop off in Madeira, the island which was directly in the trade winds between Europe and America. The wine became known as The Forgotten Island Wine. The rest of the 20th century saw a downturn for Madeira, both in sales and reputation, as low-quality "cooking wine" became primarily associated with the island—much as it had for Marsala. In 1988, the Symington family of Portugal invested in the Madeira Wine Company which owned many of the Madeira brand names. They asked Bartholomew Broadbent to re-launch Madeira and create a market for it again in America, which he did in 1989, establishing a firm rebirth of Madeira. Towards the end of the 20th century, some producers started a renewed focus on quality—ripping out the hybrid and American vines and replanting with the "noble grape" varieties of Sercial, Verdelho, Bual and Malvasia. The "workhorse" varieties of Tinta Negra Mole now known officially as just
