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.

France’s 2019 wine harvest was expected to shrink by between six and 13% versus 2018, said the agriculture ministry’s statistics unit, Agreste, this week.

It predicted a harvest of between 42.8 and 46.4 million hectolitres (hl)  – one hl is 100 litres. It did not assess potential quality.

Some winemakers disagree with forecasting the harvest when there is so much still to play for in the vineyards, but officials said rain and cold weather after the flowering period had reduced the potential crop in several regions.

‘Blowtorched’ grapes

Some areas had other specific problems.

Scorching temperatures at the end of June burnt grapes in parts of Languedoc-Roussillon, prompting a supportive visit from agriculture minister Didier Guillaume.

‘Some vines looked like they had been blowtorched,’ Jérôme Despey, president of the agriculture chamber in the Hérault area, was quoted as saying.

Local authorities issued an alert to winemakers this week ahead of another spike in temperatures, advising them to protect grapes from direct sunlight.

Frost

Further east, frost may have cut Jura wine production by 40% versus a ‘normal year’ and it also hit vineyards in Burgundy’s Mâconnais area.

Water stress

Water could become an issue if hot, dry weather continues.

Most areas were below the 30-year average for water content in the soil as of 1 July, said Agreste.

But, things looked brighter in Bordeaux – although temperatures this week in the city have hit the highest ever since records began.

Its overall harvest was still expected to shrink in 2019, yet the report said water stress was less severe and hot weather has reduced diseases pressure.

Some producers there might be see production increase after unprecedented mildew attacks in 2018; as ever, it is difficult to generalise.
