Chateau Maine Blanc is a red Bordeaux wine from the Blaye Cotes de Bordeaux (or Cotes de Bordeaux Blaye depending on where you look) appellation which is located on the right bank of the River Gironde. It surrounds the slightly better known Cotes de Bourg. It was previously known as Premieres Cotes de Blaye.
Chateau Maine Blanc is located near the village of Cars which is located approximately 4 or 5 kilometres to the east of the town of Blaye. The vineyards are located on clayey-calcareous soils and cover some 5 hectares. They are planted with 85% Merlot, 10% Malbec and 5% Cabernet Sauvignon with an average vine age of 30 years old.
The vineyard is currently converting to organic viticulture with the use of green, cereal-based fertilisers, and organic and phytotherapy treatments for the vines. In the vineyard they do some deleafing in June and a green harvest in mid-July. The harvest is done at dawn, with a manual sorting, to ensure that the grapes arrive at the winery cool and in the best condition.
After harvest the grapes undergo a period of cold maceration followed by traditional vinification in concrete vats with regular pumping over. The wine is aged in a combination of vats and second and third fill barrels.
