The English professor Charles Cocks (+1854) published a book in 1846 under the title "Bordeaux, its Wines and the Claret Country" Châteaux in the French wine region Bordeaux by describing and qualitatively evaluating these and their wines. In this regard, he said that the price (for a bottle) seemed to be the best touchstone of the quality assumed in every wine. The book was published nine years before the famous Bordeaux Classification of 1855. The most important evaluation criterion for the wineries was also the price that the wines of the Châteaux had achieved in the past hundred years. And there were also great similarities in the ranking of Cocks and that of the brokers from Bordeaux, who there according to the imperial order of Napoleon III. (1808-1873) carried out the classification.
The book was translated into French in 1850 in collaboration with the French bookseller Michel-Édouard Féret under the title "Bordeaux et ses vins" (Bordeaux and its wines). After Cock's death, Féret published a second edition, revised by himself, in 1868, which gives a historical overview of the development of quality in various wineries and areas. This is what is famous today Château Petrus just as a simple one Cru bourgeois classified. The work has become profanely famous under the name "Bordeaux Bible", but is officially known as "Féret" (also "Édition Féret", "Cocks-Féret" or "Cocks et Féret"). It has been published in an updated form since 1850; the 19th edition took place in 2014. In the French edition with around 2,300 pages, 14,000 châteaux or wines from 400 municipalities and 15,000 people are described. See also under literature and Viticulture personalities,
