The 1811 vintage was exceptional in many European wine-growing regions and is called 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 of this vintage are also called "Napoleon wine" because the Emperor Napoleon (1769-1821) was at the peak of his fame at that time. This was also the year in which his son Napoleon II was born. A Château d'Yquem from this vintage sold for €85,000 in 2011 and is one of the most expensive wines in the world. Wines from that year were also dubbed wines of the century. Popularly, the name Comet Wine was 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 wine quality.
