Ch Teyssier is located in the tiny wine appellation of Montagne Saint Emilion. The vineyard dates to 15th century and it surrounds a charming 18th-century chartreuse. The estate has been run since 1993 by Antoine Darquey; he and his cousin Thomas Durand Teyssier represent the fourth generation of their family here. Early on, Antoine worked with the consultant Michel Rolland to renovate the property. Stéphane Derenoncourt is now the consultant here. The 51-hectare vineyard is split roughly evenly between Montagne and Puisseguin; it includes 10 hectares of rented vines.
