Madeira, a remote volcanic island located in the Atlantic Ocean, gained prominence for its wines during the Age of Exploration, serving as a vital stopover on voyages to the Americas. Madeira wine stands out for its unconventional aging methods, deliberately incorporating practices typically avoided in winemaking. Unlike traditional wines, Madeira undergoes deliberate heating (estufa), cooling, oxygen exposure, and evaporation during aging.
Among the many grape varieties grown on the island, a few stand out: Tinta Negra Mole, Sercial, Verdelho, Bual (Boal), and Malvasia (Malmsey). with the four noble varieties—Sercial, Verdelho, Bual, and Malvasia—along with Terrantez and Tinta Negra dominating. These noble grapes, known for their traits, form the backbone of Madeira wine production.
