Louis Roederer is one of the largest remaining independent Champagne Houses, owned by the Rouzaud family since it was founded in 1776. It is most famous for producing the premium champagne Cristal. It is based just south of Reims, France. Tsar Nicholas II nominated Louis Roederer as the official wine supplier to the Imperial Court of Russia. Thus it became known as the 'Champagne of the Tsars'. The Russian Revolution and Prohibition in the United States caused the company to lose major ground during the early 20th century, though it quickly re-established itself during the Great Depression as an eminent wine-producer.Wikipedia
