How is white wine produced
Published on May 19, 2023
Wine has been an integral part of human culture for centuries. There are countless varieties and types of wine, depending on the grape variety from which it is made and how it is produced. This article is about the production of white wine, a wine made from white or slightly greenish grapes. We will take a closer look at the different steps of production and explain how they affect the taste and quality of the wine.
Step 1: The grape harvest
The grape harvest is the first step in the production of white wine. It usually takes place in late summer or early fall, when the grapes are fully ripe. The timing of the harvest is critical to the taste and quality of the wine, as the grapes have the highest sugar and acid content at this time.
The grapes are harvested by hand or by machine. Hand harvesting is more time consuming, but it allows for a more selective harvesting of the grapes, thus ensuring a higher quality wine. Machine-harvested wine, on the other hand, is harvested more quickly and is usually less expensive.
Step 2: The grape processing
After the grapes are harvested, they must be processed to make the wine. First, the grapes are de-stemmed, meaning the stems are removed, as they can have a bitter taste. Then the grapes are pressed to extract the juice. The juice is then stored in stainless steel tanks or barrels to ferment.
Step 3: The fermentation
Fermentation is a natural process that converts the sugars in the grapes into alcohol. Carbon dioxide and heat are also released in the process. Fermentation can take place in two ways: by natural fermentation or by added yeast.
In natural fermentation, the conversion of sugar into alcohol is done by the yeast present on the grape skin and in the cellar. This method is more difficult to control because different types of yeasts and bacteria can affect the fermentation process.
In added yeast fermentation, special yeast is added directly to the grape juice to accelerate and control fermentation. This allows the winemaker to better control the flavor and aroma of the wine.
Step 4: The maturation
After fermentation, the wine must age to develop its flavor and aroma. Aging can be done in stainless steel tanks or in oak barrels. The type of aging influences the taste of the wine. Stainless steel tanks usually produce fresher and fruitier white wines, while oak barrels give the wine a spicier and more complex aroma.
Aging can also take place in the bottle, where the wine is bottled after fermentation and then stored for several months or even years. Some white wines can be enjoyed after a short period of aging, while others take years to reach their full potential.
Step 5: The bottling
Once the wine has matured sufficiently, it is bottled and sold. Bottling is usually done in glass bottles, but bag-in-box or cans are also possible. The bottles are usually sealed to protect the wine from oxygen and light, which can affect its quality.
Conclusion
The production of white wine is a complex process that involves several steps, all of which affect the taste and quality of the wine. Harvesting is the first and most important step, followed by grape processing, fermentation, aging and bottling. Choosing the right method and technology can significantly affect the taste and aroma of the wine. With the right ingredients, the appropriate methods and a lot of patience, an excellent white wine can be created, which will beguile the senses of the connoisseur.
