Vinification is the process that transforms the grapes into wine. The process of vinification differ from region to region, financial state of the winery and the grape types. The harvesting time and the type of oak used for aging are based on the region in which the wine grapes are grown.

Wine making process involves the following stages:

  • The first step in wine making process is Harvesting or Picking. Grapes should be harvested at the right time in order to make good wine. Harvesting can be done either mechanically or by hand.
  • The process of separating the grapes from the stems and cluster parts is called Destemming. Some of the wine makers keep some fragments of the stem to increase the wine tannin.
  • After destemming the grapes are crushed to extract the juice from the skin. This is done before the fermentation process begins. In the olden days bare feet is used to extract the grape juice, now a day machines like crushers are used.
  • Separation of grape juice and the skin is named as pressing. After crushing the grape juice will flow freely, selected wineries use pressers to make sure maximum juice is released.
  • Once the grapes are pressed they are introduced into the process of fermentation. During this process the grape juice are converted into alcoholic beverage. The yeast interacts with the sugar in the grape juice and converts them into ethanol and carbon dioxide.
  • Once the wine is purified and refined, they are preserved with sulfur dioxide or potassium sorbate. During the natural process of fermentation a minimum amount of sulfites are produced, but more is added for the use of commercial preservation.
  • Wines are aged for a particular amount of time to get more welcoming wine. Once after purification, the wines are moved to wooden barrels for aging. Metal vats, concrete vats and glass carboys are also used in some cases to increase the flavor.
  • After aging, the wines are bottled. During the process of bottling a final dose of sulfite is added to the wine to prevent it from uninvited fermentation in the bottle. The bottles are then sealed with cork and screw caps.

An Italian entrepreneur plans to launch a leather made from wine extracts in Milan later this year.

Think luxury goods. Think leather. Think wine. Think wine leather – a simulated leather made from grape skin and seed fibres, currently provided by organic Italian winemakers.

The new material, in the form of prototype garments, bags and other fashion accessories, will have its official launch this October in Milan.

It could potentially reduce pressure on a range of animals and reptiles, including cows, donkeys, ostriches, dogs, alligators and crocodiles, to provide their own pelts.

Creator, Milan-based architect Gianpiero Tessitore, says the product is aimed at consumers who prefer to spend money on green and cruelty-free alternatives to animal and oil-based synthetic leathers.

After the official launch, Tessitore will begin sorting through the various business proposals he has already received, from both wineries and fashion brands, to find a collaborator for the next stages.

Businesses outside the wine and fashion industry may also be interested. According to the advocacy group, People for the Ethical Treatment of Animals (PETA) BMW already produces a car with vegan interiors, as do Buick, Chevrolet, Honda, Hyundai, Volkswagen and others.

Work on the wine leather project began in 2014, in cooperation with several Italian research centres and the University of Florence. By June 2016 Tessitore had patented the wine leather production process and launched his company, Vegea.

Asked about costs, Tessitore said the grape marc (as the vegetal wine by-product is known) is free, while the necessary machinery already exists, helping to make large scale wine-leather production a competitive alternative to skin.

Along with its green and cruelty free creds, Tessitore says Vegea is also highly sustainable, with the 26 billion litres of wine produced annually, providing an estimated seven billion kilos of grape marc, from which he could potentially produce three billion square metres of wine leather.
