The Moment of Harvest

Here we are, as every year our carts are filled with ripe and fragrant grapes. But not just ripe. Because to obtain a good wine, the grapes must reach a specific ripening balance, depending on the grape variety and the type of wine desired.

Grapes are not simply ripe or unripe, but undergo a very complex process, involving very different phases.

During ripening, the concentration of sugars increases, while that of acids gradually decreases (the so-called technological ripening): for grapes intended for sparkling wine bases, an acid-sugar ratio leaning towards acidity will be maintained; for our Moscato d'Asti, however, there will be balance.

Phenolic ripening involves phenolic substances, namely anthocyanins, responsible for the color of the grapes, and tannins which act as natural antioxidants. Aromatic ripening, fundamental for our Moscato and Brachetto, occurs when the peak of terpenes is reached, which give the unique aromas of Strev, Scrapona and Pineto wines.

A territory is defined as suitable for viticulture when technological, phenolic and aromatic ripening tend to coincide.

When experience tells us that the time has come, samples are collected for laboratory analysis. Based on the results, and the essential tasting of the berries, the actual harvest proceeds. Or we wait a few more days and repeat the analyses and tastings.

Heat waves, thunderstorms, temperature changes, unpredictable seasons: harvesting the precious grapes is a real challenge that is rooted in work, experience and science. Perfect ripeness is a fleeting moment that must be indulged and seized.
