How much wine to leave before pressing

Winemaking is a delicate and intricate process that requires careful attention to detail at every step. One important stage in the winemaking process is determining how much wine to leave before the grapes. This decision can greatly impact the final quality, flavor, and characteristics of the wine produced.

Before the pressing stage, grapes are typically harvested and destemmed, allowing winemakers to separate the grape berries from the stems and leaves. The grape berries still contain a significant amount of juice, and it is this juice that will eventually become the wine. However, it is essential to leave a certain amount of wine behind before pressing to maintain the desired quality and taste.

The amount of wine to leave before pressing varies depending on several factors, including the type of grape, the ripeness of the fruit, and the winemaker’s preference. Generally, winemakers aim to leave around 15-30% of the grape’s juice in the skins and seeds. This portion of the juice is known as the free-run juice.

The free-run juice is often considered superior to the juice obtained through pressing. It is lighter in color, less tannic, and more delicate in flavor. By leaving a portion of the juice behind, winemakers can retain the desired characteristics of the grape variety and create a wine with better balance and complexity.

Pressing the grapes extracts the remaining juice trapped in the skins and seeds. This juice is known as the press wine, and it contributes more tannins, color, and body to the final wine. Press wine is not necessarily of lower quality, but it usually has a slightly different flavor profile compared to the free-run juice. The winemaker needs to find the right balance between these two components to achieve the desired style and character of the wine.

The decision of how much wine to leave before pressing also depends on the winemaking philosophy and goals. Some winemakers may choose to include a higher percentage of press wine to add structure and complexity to their , while others may prefer to primarily utilize free-run juice for a more delicate and elegant expression.

The ripeness of the grapes is another important factor to consider when determining how much wine to leave before pressing. Riper grapes tend to have more extractable phenolic compounds, such as tannins and pigments, which can influence the amount of press wine needed. In general, riper grapes may require less press wine to achieve the desired flavor and color intensity.

Winemakers also consider the grape variety when making this decision. Some grape varieties have thicker skins and more abundant tannins, which can lead to a higher percentage of press wine. Other varieties may have more delicate flavors and aromas, necessitating a higher proportion of free-run juice to preserve their subtleties.

In conclusion, the decision of how much wine to leave before pressing is a crucial step in the winemaking process. This choice can significantly impact the final flavor, color, and structure of the wine. By carefully balancing the amount of free-run juice and press wine, winemakers can create wines that showcase the best qualities of the grape variety and reflect their desired style.
