The land

Madeira is a volcanic Portuguese island in the Atlantic, 500 miles southwest of Lisbon and roughly the same latitude as Casablanca. The vineyards are perched on dramatically terraced slopes carved from the island’s volcanic terrain, often at significant elevation. The climate is subtropical, with high humidity, abundant rainfall, and consistent temperatures year-round. The wines are unlike anything else made — partly because of the unique terroir and partly because of the heating process (estufagem or canteiro) that is applied to all serious Madeira.

How Madeira is made

Madeira’s unique character comes from deliberate oxidation and heating. After fermentation and fortification, the wines are deliberately heated — either in stainless-steel vats heated by coiled pipes (estufagem) for cheaper styles or in casks stored in warm attics for years (canteiro) for the better wines. The heating concentrates flavors, develops caramelized notes, and stabilizes the wine such that an opened bottle stays fresh for months and a closed bottle stays drinkable for centuries. Madeira from the 1700s and 1800s, properly stored, is still drinking — some of the longest-lived wines ever made.

The styles

Four grape-based styles (in order from driest to sweetest): Sercial (driest, lemon-and-walnut character), Verdelho (off-dry, smoky-honey character), Bual/Boal (sweet, caramel-and-figs character), Malmsey/Malvasia (sweetest, deep caramel-and-toffee character). Two ungraded styles: Tinta Negra (the workhorse grape that fills the rest of production) and Terrantez (the rare grape that produces some of the most coveted bottlings). Age statements include 3-Year, 5-Year, 10-Year, 15-Year, 20-Year, 30-Year, 40-Year, and Frasqueira (vintage Madeira, minimum 20 years cask-aged before bottling).

Vintages to know

Madeira vintages from the great historical years — 1900, 1908, 1920, 1933, 1934, 1954, 1960, 1980 — are still drinking remarkably. The wine is essentially indestructible.

Producers we know

Blandy’s, Henriques & Henriques, Cossart Gordon, Barbeito, D’Oliveira, Justino’s. The historical Madeira market has been consolidated to a handful of major houses, but the depth of their library stocks means rare bottlings from 100+ years ago still appear at auction.
