Winemaking Production Of Wine From Choosing Grapes To Packing

Winemaking also called as vinification refers to the process involved in the production of wine. It initiates from the choice of grapes to the final packing of the wine into the bottles. The making of wine is divided into two broad categories namely still wine production, which is carried out without carbonation and sparkling wine production with carbonation.

The science of winemaking is called as oenology. Little quantities of wine are fermented by the winemakers through carboys. Once the harvest is completed the crushing of grapes is done and is left to ferment. The preparation of red wine is carried out from the must or pulp of red or black grapes, which is led through the fermentation process along with the grape skins. On the other hand the white wine is ususally made by fermenting the juice that is taken out from white grapes.

However white winemaking can also be done from the must that belongs to the red grapes but it should be least exposed to the grapes skins. In the preparation of Rose wines the red grapes are put to use and in it, the juice is kept with the dark skins so that a pinkish color appears with the least of tannings of the skins. The primary fermentation is completed in a span of one and two weeks and during this period the yeast changes the sugars contained in the grape juice to ethanol (alcohol).

The next stage is secondary fermentation for the purpose of which the liquid is poured into the vessels and the rest of the sugars gets transformed to alcohol making the wine clear. After this is done with the wine is left to age in oak barrels that provides appealing aromas to them. The quality of wine is mostly influenced by the quality of grapes that are used in winemaking, which is further dependent on the weather that prevailed at the time they were growing, the soil, the harvesting season as well as the process involved in pruning.

The popular species of wine grapes is Vitis vinifera and it is comprised of all the different kinds belonging to the European origin. In order to minimise the amount of tartrate crystals in wine the process of Cold stabilization is used. In the process of winemaking, the fining agents are applied for the purpose of eliminating tantins, astringency, as well as microscopic particles that might cloud the wines. The method that has been traditonally carried out for wine fining is the use of gelatin and the other agents are lysosyme, isinglass, egg whites to name a few. Wine making
