Saint-Émilion wines were first classified in 1878 and have been continuously revised with the most recent revision occurring in 2006. Chateaux are divided into two First Growth classifications – "Premiers Grands Crus Classés A", which currently includes Château Ausone and Château Cheval Blanc, and "Premiers Grands Crus Classés B", which currently includes 13 chateaux such as Château Angélus and Château Figeac. Below the Premiers crus are the "Grands Crus Classés" which currently includes 55 chateaux. Estates can apply for classification by passing two tasting panels.
