Madeira is the world's most indestructible wine — a volcanic Atlantic island 600km off the Moroccan coast producing wines of extraordinary longevity through a deliberate oxidation and heating process (estufagem or canteiro) that was originally accidental. The four noble varieties map to sweetness level: Sercial (driest, high acidity, 18–25 g/L RS), Verdelho (medium-dry, 25–65 g/L), Bual (medium-rich, 65–100 g/L), Malmsey/Malvasia (richest, 100–150 g/L). Vintage Madeira from pre-phylloxera vintages (1862, 1875, 1880) is still commercially available and drinkable — no wine in the world demonstrates longevity more conclusively. The Madeira Wine Institute (IVBAM) governs production. Blandy's, founded 1811, is the reference shipper.
| Year | Rating | Notes |
|---|---|---|
| 2010 | 93 | One of the finest Madeira harvests of the 21st century — canteiro-aged expressions now 13+ years old and in excellent early development. |
| 2000 | 92 | Millennium harvest — a useful benchmark for understanding younger vintage Madeira development. These wines are now 23 years old and showing early complexity. |
| 1990 | 94 | Excellent Madeira harvest — the wines are now entering prime complexity at 33+ years. Particularly successful for Bual and Malmsey. |
| 1976 | 96 | The benchmark year for modern vintage Madeira — producing wines of extraordinary complexity now 47+ years old. Blandy's and D'Oliveiras 1976 Sercial and Bual are reference examples of mid-century quality. |
