Wine is an alcoholic beverage fermented from grape juice. Made from pure and naturally fermented grapes. Because grapes have two natural properties, sugar and yeast, grape juice is pressed, undergoing a processing process, and becomes wine.
However, the wine products that we enjoy today cannot be made by nature, but by human hands. It is people who have made the winemaking process more and more perfect. In this article, we will describe the production process of fine wine bottles, please take a look! Learn about the grape growing process here.

Wine grapes production process

Harvesting grape

Most vineyards are harvested starting with the white varieties, followed by the red grapes. The harvested grapes will be put in the barrel.
Grapes are placed in baskets during harvest. After the harvest is complete, the grapes will be moved to an area with a branch stripping machine and a grape press. Generally, there are 2 forms of grape harvesting. Harvest by hand and harvest by machine. Hand-harvesting allows farmers to select grapes of the right ripeness according to the producer’s wishes. Of course, it will take more time and the day’s harvest will not be able to keep up with harvesting with modern machines or equipment.
Grape harvest can take place during the day. Or it can also be at night for maximum effect. Not only will it help to avoid the heat, but harvesting at night will keep the sugar levels in the grapes stable.

Grape pressing stage

Regardless of when or how the grapes were picked, they are all pressed in this step. This is where the grapes are separated from the stem and gently pressed.
– For white wine: the white grapes are transferred to the press to extract juice. Grape skins will be discarded. The grape juice has just been taken, it is put into the storage tank for the sedimentation process to take place. After a while, when the sediment settles, the upper part of the grape juice is transferred to another container. The goal is to make sure the residue is gone before fermentation takes place.

– For red wine: the red grapes are usually gently pressed. The difference from the white grape pressing process is that both the skin and the grape juice are put in the same tank to start the fermentation process. How long it takes to soak grape skins and grape juice to achieve the desired color is up to the producer. Interestingly, red grapes can also make white wine.

Fermentation

Simply put, fermentation is the process by which yeast eats sugar and produces alcohol. There will be a variety of technologies and techniques used throughout this process. The yeast will be placed in a container for fermentation to take place. Particularly for red wines, carbon dioxide is released during fermentation. It causes the grape skins to be pushed to the surface. Winemakers must submerge the rind several times a day to increase the density of skin-to-grape contact.
Fermentation for Red Wine Since the first is gently pressed, after fermentation, the red grapes are pressed again. After that, the grape juice is filtered before being aged in wooden barrels for a few months.

Wine maturation stage

Winemakers have a lot to choose from during this period. It depends on what kind of wine they want to make. The aromas of wines are strongly influenced by the following winemakers’ choices:
+ Age of wine: many months or many years
+ Material of aging barrels: stainless steel or oak barrels
+ Newness of aging barrels: using 100% new, 70% new oak barrels. Or used oak barrels many times
+ Type of barrel: American oak barrels or French oak barrels

Bottling process

Once the winemaker feels that the wine has reached sufficient maturity, bottling and labeling takes place to begin consumption. Some white wines will be bottled after several months of aging. While red wines need 18-24 months of aging before entering the bottling process.
