THE LIFE CYCLE OF A GRAPEVINE Each year, the grapevine develops in rhythm with the seasons, following a plant cycle divided into several stages. During winter, the grapevine enters a period of hibernation, known as winter rest. The sap no longer circulates through the plant. Winegrowers prune their vines in order to remove vine shoots and selects the buds that will grow and produce the next year’s fruit. Spring it the time for the débourrement: when the buds begin to develop. This is the period when the vine branches and leaves grow. The grapevine comes back to life and sap once again circulates through the plant. May  and June see the plant flowering, with small flowers appearing.    In the summer, foliage continues to develop and the flowers transform into  grape seeds. August is the time of véraison: the  unripe grapes grow bigger and ripen. They turn either red or white, become less acidic and increase their sugar content and flavour. Finally, autumn is the time for the grape harvest.    The grapes are harvested either by hand or by a grape harvester. The vineyard at Espondeilhan: a touch of Tuscany in Languedoc. THE MAJOR PRINCIPLES OF VINIFICATION The 18th century winery at Château de Raissac THE AOC AND IGP APPELLATIONS Identified and certified wines linked to a geographical area enjoy international protection. As a result, they have an appellation and a logo, signifying their origin and recognised quality in Europe. In this way, AOCs - appellation d’origine contrôlée - guarantee a level of quality of the vineyards that meet established specifications. Specific geographical areas called ‘denominations’ are determined within the appellation system to allow them to distinguish themselves. Thus, we can talk about the Languedoc AOC and the Fonseranes denomination, currently being certified by INAO (institut national des appellations d’origine). Protected Geographical Indication, or IGP in French, replaces the former term of ‘vin de pays’. As a result, the consumer can taste the products offered in total confidence. These are often blended varieties, produced in 3 colours, with a large proportion of rosés, even if reds dominate. They are created by independent, inventive winegrowers, cooperatives and  privately- owned wineries, subject to strict specifications and rooted in a territory which identifies them.  Thus, you will find Coteaux de Béziers, Coteaux d’Enserune, Côtes de Thongue and Pays d’Oc IGPs. The operation which enables the grapes to be transformed into wine is called vinification. It takes approximately 1.3 to 1.5 kg of grapes  to obtain a litre of wine. The key stages of vinification are destemming, pressing, maceration and fermentation. The order of the stages differs depending on the type of wine to be created. The grape variety also affects the type of wine obtained.  Alcoholic fermentation, the main stage of vinification, is a natural phenomenon during which the sugar from grapes turns into alcohol through the effect of yeast. This transformation is accompanied by the release of carbon dioxide gas. This is the same gas contained in champagne (its production occurs naturally in the bottle) that makes corks pop and bubbles form.  Vinification is a delicate operation that depends on the skill of the winemaker and the oenologist for its success. After pressing, the wine is clarified, stabilised and then matured (in oak barrels if it is to be matured “sous bois”). Depending on the type of wine required, the period of fermentation “sous bois” will be longer or shorter. It allows the wine to open up through a slow evolution, at the end of which the wine is filtered and bottled.  7
