how wine is made

As a drink with a long history, wine’s production process combines traditional craftsmanship with modern technology. This article will introduce the steps of making wine in detail and attach relevant data to help readers fully understand the process.

1. Grape planting and picking

The quality of wine depends first on the quality of grapes. The cultivation of grapes requires suitable climate, soil and light conditions. The following are the climate characteristics of major wine-producing regions around the world:

The timing of grape picking is crucial and is often determined based on the balance of sugar and acidity. Here are the ripening periods for different grape varieties:

2. Grape pressing and fermentation

After picking, the grapes need to be pressed to separate the juice from the skins. The pressing methods are divided into manual pressing and mechanical pressing, the latter is more efficient. The following is the composition of the juice after pressing:

Fermentation is the core part of wine making. Yeast converts sugar into alcohol and carbon dioxide. Fermentation temperatures and times vary depending on the type of wine:

Aging times vary depending on the type of wine, usually red wines take longer:

Bottling is the final step in wine making. Filtration and stabilization are often performed before bottling to ensure the wine is clear. The following are storage recommendations after bottling:

Conclusion

Wine making is a combination of science and art. From grape growing to final bottling, every step affects the quality and flavor of the wine. I hope that through the introduction of this article, readers can have a deeper understanding of the wine production process.
