Madeira

Madeira was discovered in 1419 by the Portuguese captain João Gonçalves Zarco, and the island was settled and its forests cleared after 1420. Winemaking dates to the Age of Exploration, when Madeira became a standard port of call for ships heading to the New World and the East Indies. With commercial treaties with England, notably the Marriage Treaty of 1662, important English merchants settled on the island and came to control the increasingly important wine trade. The eighteenth century was the golden age of Madeira, when American colonies consumed as much as 95% of all wine produced on the island each year. The mid-19th century brought twin crises: powdery mildew arrived in 1851 and devastated vineyards for several years, and then phylloxera struck in the 1870s, reducing the island's vine acreage dramatically by the 1880s.

• Cossart Gordon, founded on September 12, 1745 by Francis Newton, is the oldest company in the Madeira wine trade; William Cossart, an Irishman of Huguenot descent, joined the firm in 1808
• Blandy's was founded in 1811 when John Blandy established himself as a wine shipper; seven generations of the family have been directly involved in Madeira production
• Madeira played a significant role in American history, reportedly used to toast the signing of the Declaration of Independence in 1776
• Post-phylloxera, many growers replanted with American hybrid varieties, which were officially banned from Madeira wine production in 1979

Madeira is a volcanic archipelago in the North Atlantic Ocean, situated 520 km (320 mi) west of Morocco. The main island, covering 741 square kilometers, is steeply mountainous, with a central ridge rising to over 1,800 meters and creating several distinct microclimates that strongly influence where vineyards can be planted. The climate is subtropical and temperate overall, with mild temperatures and high humidity, though conditions vary sharply from the wet northwest to the drier south coast. Most vineyards are found on the south-facing slopes around Funchal, while the north side of the island has dense laurisilva forest, a UNESCO World Heritage Site. Vines are trained on low pergolas on steep terraces, meaning virtually all vineyard work is done by hand.

• The island's volcanic soils are rich in minerals; grapes grown at lower coastal altitudes can develop distinctive saline and iodine notes
• A mountain range running the length of the island peaks at 1,862 meters (Pico Ruivo) and creates seven distinct microclimates
• An ancient network of irrigation channels called levadas, built between the 15th and 19th centuries, carries water from the wet northwest to the dry southeast
• The archipelago includes two inhabited islands, Madeira and Porto Santo, plus the uninhabited Desertas and Selvagens; Porto Santo grapes may also be used for Madeira production

The four major white noble grape varieties used for Madeira production are, from driest to sweetest: Sercial, Verdelho, Bual (also spelled Boal), and Malvasia (Malmsey). Each variety corresponds to a recognized style of Madeira, from bone dry and piercingly acidic to rich, luscious, and sweet. Tinta Negra is by far the dominant workhorse variety, representing approximately 85% of total production by volume, and since 2015 can be listed on the label in its own right. The rare Terrantez variety is considered a fifth noble grape and produces off-dry wines of great complexity; it nearly went extinct after phylloxera but is the subject of ongoing revival efforts. Bastardo, an ancient red variety, survives in only tiny quantities.

• Sercial: driest style (RS up to 27 g/L), high acidity, almond and citrus character, best served chilled as an aperitif
• Verdelho: medium-dry (18–45 g/L RS), spiced fruit and smoky notes, vibrant acidity, versatile as aperitif or with food
• Bual (Boal): medium-sweet (45–64 g/L RS), rich dried fruit, spice, and caramel; excellent aging potential
• Malvasia (Malmsey): sweetest noble style (over 64 g/L RS), opulent, coffee and dried-fruit richness balanced by signature Madeira acidity

What makes Madeira unique is its deliberate use of heat and oxidation during aging. Younger commercial wines undergo the estufagem process, in which fortified wine is placed in large coated vats and gradually heated to 45–50°C for approximately three months, then rested in wood for a minimum of two additional years. Premium wines are aged by the canteiro method, stored in seasoned oak casks in the warm attics of wine lodges, heated only by the natural warmth of the Madeiran sun. The word canteiro refers to the wooden beams on which the casks sit. Blandy's, part of the Madeira Wine Company, is the dominant force on the island and also represents Cossart Gordon, Leacock, and Miles. Pereira D'Oliveira, founded in 1850 and housed in cellars dating to 1619, holds the largest library of old vintage Madeiras on the island. Justino's, founded in 1870, is the island's largest volume producer.

• In 2011 the Blandy family signed an agreement with Symington Family Estates, regaining majority control of the Madeira Wine Company; Symingtons continue as a minority shareholder
• Cossart Gordon, established in 1745 by Francis Newton, is the oldest company in the Madeira wine trade; by 1850 it was reportedly shipping half the island's entire production
• Pereira D'Oliveira, founded in 1850, holds approximately 1.5 million liters of mature Madeira in its cellars; all vintages are kept in cask and bottled only to meet demand
• Justino's, established in 1870, produces around 1.5 million liters per year and also bottles wine under the Broadbent label for the North American market

IVBAM (Instituto do Vinho, do Bordado e do Artesanato da Madeira) oversees all production and commercialization of Madeira wine. The EU regulations of 1986 require that any wine naming a grape variety on its label must contain at least 85% of that variety. In 2015, Tinta Negra was officially elevated to a Recommended varietal, allowing it to appear on labels alongside style descriptors. Madeira's classification by sweetness spans six categories from Extra-seco (up to 9 g/L RS) through Doce/Malvasia (over 64 g/L RS). By age, approved categories include 5, 10, 15, 20, 30, 40, 50 and over 50 Years Old. Colheita designates a single-harvest wine aged in cask for a minimum of five years, while Frasqueira (or Garrafeira) denotes the highest tier: a single-vintage wine aged in cask for a minimum of 20 years before bottling.

• Six sweetness categories: Extra-seco (up to 9 g/L), Seco/Sercial (up to 27 g/L), Meio-seco/Verdelho (18–45 g/L), Rainwater (18–45 g/L), Meio-doce/Bual (45–64 g/L), Doce/Malvasia (over 64 g/L)
• Estufagem: vat heating at 45–50°C for minimum 3 months, controlled by IVBAM; wine must rest at least 2 years in wood before release
• Canteiro: natural attic heat in oak casks, minimum 2 years; Colheita requires minimum 5 years; Frasqueira requires minimum 20 years
• Madeira DO requires a minimum total alcohol of 17.5% ABV and acquired alcohol of at least 17% ABV; all wines must carry IVBAM's registration seal

Funchal, the capital, is home to the major wine lodges and is the gateway to Madeira wine tourism. Blandy's Wine Lodge, housed in a 17th-century building in the center of Funchal, is one of the island's most visited attractions, featuring hundreds of aging barrels, a family museum, and guided tours in multiple languages. Pereira D'Oliveira's lodge on the Rua dos Ferreiros in Funchal occupies cellars dating to 1619 and offers tastings of wines stretching back to the mid-19th century. Henriques and Henriques, based in Camara de Lobos outside Funchal, is another key producer offering tastings. The island's dramatic landscape, with its terraced vineyards, levada walking paths, and laurisilva forest, draws visitors from across the world beyond wine tourism alone.

• Blandy's Wine Lodge is located in the center of Funchal in a historic building; the Blandy family is unique in being the only founding family of the Madeira wine trade still owning and managing their original company
• Pereira D'Oliveira's cellars in Funchal date to 1619, making them among the oldest winemaking facilities on the island
• The levada irrigation network, built between the 15th and 19th centuries, now provides over 2,150 km of walking paths across the island
• Justino's, the island's largest producer, is based in Canico between Funchal and the airport and holds vintage stocks dating back to the 1930s
