Bordeaux wine almost universally used. Chaptalization is permitted, and is fairly common-place. Fermentation then takes place, usually in temperature controlled stainless steel vats. Next the must is pressed and transferred to barriques (in most cases) for a period of ageing (commonly a year). The traditional Bordeaux barrique is a 225 litre oak barrel. At some point between pressing and bottling the wine is blended. This is an integral part of the Bordeaux wine making process, as scarcely any Bordeaux wines are varietals; wine from different grape varieties is mixed together, depending on the vintage conditions, so as to produce a wine in
Bordeaux wine regions greater than the amount of white wine produced (around 170,000 litres from 60 hectares). Rosé wine produced under the Bordeaux Rosé AOC is made from Cabernet Sauvignon, Merlot and Cabernet Franc. As is usual for Rosé, the grape skins are briefly left in contact with the must, but are removed prior to fermentation. This appellation covers around 4725 hectares of vines and 17 million litres of wine. Bordeaux Clairet AOC is intermediate between red and rosé wine, and is made from the same grapes as Bordeaux Rosé but undergoes a longer maceration (between 24 and 48 hours). Production is around
