The 1811 vintage was exceptional in many European wine-growing regions and is considered the best of the past three centuries before. Among others, the red wines of Château Lafite-Rothschild (then Château Lafite) and Château d'Yquem, a Riesling from the Bassermann-Jordan winery and Tokay in general are mentioned. Wines from this vintage are also called "Napoleon wine" because the Emperor Napoleon (1769-1821) was at the peak of his fame at the time. His son Napoleon II was also born in this year. A Château d'Yquem of this vintage sold for € 85,000 in 2011 and is one of the most expensive wines in the world. The wines from that year were also dubbed the wines of the century. The name Comet Wine was popularly coined because of the appearance of a comet discovered by Honoré Flaugergues (1755-1830), which was one of the three largest ever sighted; its tail length was well over 100 million kilometres. The comet was said to have an influence on the outstanding quality of wine.
