Why grapes with low potential alcoholic volume are not suitable for winemaking

Wine production is a meticulous process that demands careful selection of ingredients and specific conditions to ensure a quality final product. A crucial factor in this process is the grape selection, as grapes are the fundamental raw material for wine production. In this context, it is important to note that grapes with a potential alcoholic volume below 9 cannot be used for winemaking.

Alcoholic volume is a measure of the amount of ethyl alcohol present in a liquid solution. In the case of grapes, this value is directly related to the amount of sugars present in the fruit, as these sugars transform into alcohol during the fermentation process.

Therefore, to obtain a quality wine, it is essential that the grapes have a sufficient amount of sugars, allowing an adequate alcoholic degree in the final product. This is one of the reasons why grapes with a potential alcoholic volume below 9 cannot be used for winemaking.

Additionally, it is important to consider that the alcoholic degree of wine is regulated by the competent authorities of each country or region. In many places, wine must have a minimum alcoholic degree to be considered as such. For example, in some countries, the legislation states that wine must have a minimum alcoholic degree of 8.5%. Therefore, using grapes with a potential alcoholic volume below 9 would not comply with this regulation.

Another factor to consider is that the alcoholic degree of wine influences its preservation. A wine with an adequate alcoholic degree has a higher resistance to the action of microorganisms and oxidation, allowing better preservation of the product over time.

Lastly, it is important to point out that the alcoholic degree of wine influences its taste and aroma. A wine with an adequate alcoholic degree will have a better balance between the different components that make it up, resulting in a more harmonious and pleasant product to the palate.

In conclusion, using grapes with a potential alcoholic volume below 9 for winemaking is not recommended, as it would negatively affect the quality of the final product, its preservation, and its ability to comply with current regulations. It is essential, therefore, to carefully select the grapes that will be used in the winemaking process, taking into account their potential alcoholic volume.

The selection of the right grape variety is vital to producing high-quality wine. There are several factors that winemakers consider when choosing the best grapes for their wine, including the grape's potential alcohol volume. The potential alcohol volume of a grape is determined by its sugar content, as the sugars in the grape are converted to alcohol during fermentation. It is crucial that the grapes have a sufficient sugar content to achieve the desired alcohol level in the final wine. Grapes with a potential alcohol volume below 9 are not suitable for winemaking as they would not produce a wine with the necessary alcohol content. This is important for several reasons.

Firstly, the alcohol content of wine is regulated by law in many countries. There are minimum alcohol levels that a wine must reach to be legally labeled as wine. For example, in some regions, wine must have a minimum alcohol content of 8.5%. Therefore, using grapes with a potential alcohol volume below 9 would result in a wine that does not meet the legal requirements.

Secondly, the alcohol content of a wine affects its preservation. Wine with an adequate alcohol content has a higher resistance to microbial activity and oxidation, which helps to preserve the wine over time. This is important for the quality and longevity of the wine.

Thirdly, the alcohol content of a wine affects its taste and aroma. A wine with the correct alcohol content will have a better balance of flavors and aromas, resulting in a more harmonious and pleasant wine.

Therefore, it is essential to carefully select the grapes used for winemaking, considering their potential alcohol volume. Using grapes with a potential alcohol volume below 9 is not recommended as it would result in a wine that does not meet the legal requirements, does not preserve well, and does not have the desired taste and aroma.
