Vieux Château Mazerat is made by Château Teyssier in St.-Emilion. Vieux Château Mazerat is in fact a “micro-cuvée” made from an 8-acre plot. It is typically 80% Merlot and 20% Cabernet Franc. Though Château Teyssier has a history in wine production that dates to the 18th century, since 1994 it has been owned and operated by wine entrepreneur Jonathon Maltus and his wife Lyn Maltus. Jonathon Maltus is an Englishman who took up the wine business in mid-life as a second career. Since the early 1990s he has been shaking up Bordeaux’s right bank making garagiste wines that earn raves from reviewers. His 2010 Le Dome won a perfect 100-pt score from Robert M. Parker Jr. Teyssier has 130 acres of vineyards in St.-Emilion. Robert M. Parker Jr. says the estate consistently “over achieves” by making excellent wines that fly under the radar of many wine buyers.
