Put the stages of grape formation and ripening in the correct order.

• A. Flowering, Fruit set, Véraison, Ripening, Extra ripening
• B. Fruit set, Véraison, Ripening, Extra ripening, Flowering
• C. Ripening, Extra ripening, Véraison, Flowering, Fruit set
• D. Flowering, Fruit set, Véraison, Ripening, Extra ripening

Answer: (D)

The stages of grape formation and ripening progress through a well-defined sequence that is crucial for vineyards to optimize their grape growing activities. The correct order begins with flowering, where the grapevine has blossoms that will eventually develop into grapes. Following flowering is fruit set, which is when the fertilized flowers develop into small berries as the ovary swells.

After the berries are set, the next important stage is véraison, marking the transition of the berries from being hard and green to softening and changing color, indicating that the fruit is beginning to ripen. This leads to the ripening stage, during which the grapes accumulate sugars, acids decrease, and flavors develop, making the fruit taste better.

Lastly, there is the stage known as extra ripening, where, if conditions allow, the grapes can continue to mature, enhancing their flavors and sugar levels further.

The sequence described in the correct answer effectively captures the natural chronological progression of these critical stages in grape development, supporting the process that leads to producing high-quality wine grapes. Each stage plays a vital role in the overall development of the grapevine and its fruit, which is essential for winemaking.
