Vieux Chateau Mazerat is a property about which David Peppercorn, in his eighties book BORDEAUX, stated that if the then proprietor was to buy some oak barrels there would be no reason why Vieux Chateau Mazerat shouldn’t be a Cru Classe like all of its neighbors. Jonathan Maltus bought the oak barrels as well as the property which is surrounded by Chateau Canon on three sides and by Chateau L'Angelus on the west. The Vineyard is stuck in the middle of ‘Cru Classé’ territory. The vineyard is a mixture of 35% very old Cabernet Franc vines and 65% Merlot on clay over limestone. The vineyard yield is held down to around four bunches to the vine. The vineyard receives two to three runs of green harvesting – at fruit set and veraison – ensuring that only the most perfect handpicked berries get into the vats. On arrival at the winery the grapes are sorted – firstly by bunch and then, after destemming, grape by grape. Only conveyors are used to transport the grapes and the wine is fermented in wooden vats after extreme cold maceration. The wines undergo malolactic fermentation in new French oak, and are barrel-aged in an air-conditioned cellar. This 2012 scored 95 points and was designated a "Cellar Selection by Wine Enthusiast Magazine who said "This is a grandiose wine with impressive dark tannins and swathes of black plum fruits. A hint of licorice and dark chocolate lies over the brooding, firm texture. Expect such a concentrated, solid and serious wine to age well. Drink from 2019."
