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.

Winemakers across France and also parts of Germany, Italy and Switzerland are counting the cost of frost damage in their vineyards after several nights that felt more like January than late April.

  • Winemakers lament ‘black Thursday’

  • Patchy but serious damage across France, from Loire to Languedoc, and in Germany, Italy, Switzerland

  • Vine shoots were left looking like ‘dried tobacco’ – French winemaker

Champagne vineyard managers were among the first to raise the alarm over frost last week, but it has emerged that many regions suffered damage.

The Aude region around Narbonne in Languedoc has been dramatically affected, according to Frédéric Rouanet, president of Vignerons de l’Aude. He told Decanter.com that a ‘large part of the vineyard area was damaged in the Aude. Some vines are totally destroyed’.

In Jura, Hervé Ligier, president of AOC Arbois, estimated that between 30% and 90% of vines suffered damage in the appellation, even in the AOC Château-Chalon.

‘With -2°C, buds have not resisted,’ he said.

In Pouilly-sur-Loire, temperatures fell to -5 ° C for six hours. After being hit by frost in 2016, the region is now, once again, affected. The first estimates suggested it would mean a 30% decrease in the size of the 2017 vintage.

In Montlouis, in Loire Valley, winemakers clubbed together faced with plunging temperatures.

‘The winemakers have lost three out of five crops in previous years and they have decided to mobilise themselves,’ said Guillaume Lapaque, director of the Federation des Associations Viticoles d’Indre-et-Loire et de la Sarthe.

They launched seven helicopters into the skies to ‘dry out the air and raise temperatures’, to stop the vineyard from freezing.

In AOC Chinon in the Loire Valley, early estimates suggested 20% of vines had been affected.

However, official damage estimates everywhere were still being refined and calculated.

In Alsace, Gérard Schaffar said that he had never seen frost of such magnitude. The vineyard of Turckheim-Wintzenheim is among the worst affected within the sector of Sigolsheim, Bennwihr and the Harth in Colmar.

‘The most advanced Gewurztraminer with promising shoots is completely grilled. It’s unfortunate to say, but it looks like dried tobacco,’ said Schaffar.

Olivier Humbrecht posted on his Facebook account, ‘Black Thursday!’. He posted a picture of Herrenweg de Turckheim.

The cold has not only affected France. The Valais region of Switzerland also saw temperatures drop well below freezing. Five-hundred-and-fifty hectares were affected, more than in 2012, with ‘significant damage’, said Pierre-André Roduit, of the Valais wine office.
