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.

Fierce flames from the Alamo fire in California’s Central Coast area damaged vines at the North Canyon vineyard owned by Treasury Wine Estates (TWE) earlier this month.

‘Fire outbreaks reached TWE’s North Canyon Vineyard with damage to approximately 10% of the vineyard,’ TWE vice president Rachel Ashley told Decanter.com this week.

Firefighters struggled to control the huge fire, first reported on 14 July, as it burned across the Santa Maria’s dry grasslands. It was not 100% contained until six days later.

TWE spokesperson James Caudill told Decanter.com, ‘We’re focused on about 90 acres (36 hectares) or so that were impacted.’

‘Grapevines are resilient,’ he said. ‘This is the point in the growing season when the crews are monitoring and working the vineyards hard to assure quality, so we will know more soon.’

Smoke taint will also be a concern. Ashley added that, because the grapes had not yet reached veraison – when grapes change colour at the start of ripening – ‘the risk of impact on fruit [from smoke damage] is lower’.

Lucky escape for Bien Nacido

Bien Nacido Vineyards, owned by the Miller family since 1968, was in the path of the wildfire, which consumed a total of 29,000 acres before local and statewide fire teams got it under control.

Vice president of Bien Nacido Marshall Miller told how his vineyard fought the blaze, after the fire jumped two fire breaks and came within 15 feet of their Pinot Noir and Syrah vines.

‘It was a two day battle, they couldn’t hold the fire on the other side of the hill. The fire moved against the wind as it worked down the hillside, it becomes its own force when it gets to that scale.’

 When another fire broke out at Whittier summer camp 10 miles away, firefighter crews had to redirect their resources to the fire that threatened more homes and lives.

Bien Nacido’s team were left to protect the vineyard from the oncoming fire, but after an outbreak a few years ago they weren’t taking any chances:

‘We invested in our own tanker trucks, bulldozers and hoses,’ said Miller. ‘We cut a firebreak and hosed the bare earth — it was our last chance hold the line.’

Bien Nacido’s crew of 30 people fought the blaze though Friday and Saturday night, finally Cali Fire and Santa Babara firefighters arrived to maintain the firebreaks and prevent hot-spotting.

‘We dodged a bullet. There’s not been a fire of this size in the past 50 years,’ Miller told Decanter.com.

Qupé and Au Bon Climat also have wineries in the Bien Nacido estate.

Their marketing director, Katie O’Hara, said, ‘The fire did get very close and we had to be evacuated. I think about five acres of vineyard were burnt, but due to smart thinking from vineyard managers and firemen, the damage was minimal.’
