In Bodegas Alejandro, Each stage of the winemaking process has a purpose. One of the most important during fermentation is the daily comeback, a key practice for extracting color, aroma and structure from wine.

When the must ferments, the skins, seeds, and solid remains of the grape float to the top and form what is known as the lees. hat. If not handled correctly, fermentation can become irregular and the wine will lose some of its character.

The importance of comebacks

He comeback It consists of extracting the must from the bottom of the tank and pouring it over the cap. This process is carried out daily for several reasons:

  • Extract color and structureThe grape skin contains the compounds that give wine its color and tannins. By wetting the cap with the must, a balanced extraction is achieved.
  • Ensure uniform fermentationIf the cap remains dry, fermentation becomes irregular and deviations may appear in the wine.
  • Control oxygenationDuring fermentation, a minimal amount of oxygen helps the yeasts to work optimally.
  • Avoid health problemsKeeping the cap moist prevents the appearance of bacteria or mold that could affect the quality of the wine.

Each wine requires a specific number of pump-overs per day, depending on the grape variety and the desired result. Bodegas Alejandro, This process is carried out with precision to ensure that each wine expresses the best of our land.
