major investment in all areas of wine making and maturing.
CARE IN HARVESTING AND CROP RECEPTION
The "Ban des Vendanges", the official starting date of grape picking decreed by the Prefect of the Gironde department, is a clarion call for the entire Bordeaux wine region. The grapes are generally picked from September onwards, by hand or mechanically, plot by plot according to the grape variety and the age of the vines, starting with the earliest, the Merlot, which is usually ready a week before the Cabernets).
So that only the grapes with the best winemaking potential are put into the vats, they are sorted increasingly on the vine or at the winery, so as to get rid of any damaged or unripe grapes and plant debris.
All the efforts made in the vineyard are further enhanced in the winery, where the latest destemmers, presses and pumps ensure that the grapes are handled as delicately as possible, thus avoiding oxidation.
VATTING AND FERMENTATION CONTROL
On most estates, the wines made from different grape varieties from vines of different ages are put into separate vats.
On the way into the vat, a small amount of sulphite is added to prevent oxidation and halt the development of harmful yeasts and bacteria. In some cases, the grape must is enriched with fermentation yeast. Controlling alcoholic fermentation and keeping the temperature between 28° and 32° are key features of successful winemaking. That is why many vatrooms in Saint-Emilion are equipped with temperature control systems.
During alcoholic fermentation, the wines are pumped over (racked) to extract as many compounds as possible from the skins by letting them sink down through the wine. The frequency of the operation depends on the ripeness of the grapes, the vintage and the terroir.
The maceration period which follows alcoholic fermentation is another important factor for quality. Maceration time is calculated exclusively by tasting, when the winemaker brings his experience and intuition to bear. Because the grapes are destemmed, the maceration phase can be extended up to four weeks, which means that the phenolic compounds can be completely extracted from the skins and pips. These compounds give Saint-Emilion wines their structure, colour and aromatic complexity.
TRADITIONAL MATURING: A PAINSTAKING BUSINESS
Once malolactic fermentation has taken place in the free-run wines and the press wines, and the various batches have been blended after long, painstaking tasting sessions, the wines have to mature. This takes place either in vats or in barrels, and the long, complex transformations help bring out the potential that the future great wines will develop later on in the bottle. Traditionally in Saint-Emilion, wines for laying down – vins de garde – are matured in 225-litre oak barrels and lasts an average of 16 to 18 months.
Many winemakers mature their wines in barrels, as this greatly enhances their character, allowing them to develop harmoniously by controlled oxidation, as well as imparting a lovely woody aroma.
