The Stages of Winemaking: From the Vineyard to the Bottle

The production of wine is a fascinating process that combines tradition with modern science. From the moment the grapes are harvested from the vine until the wine reaches our glass, several specific, decisive stages take place.

Part 1: The General Process of Winemaking

Every wine, regardless of its style, follows a core path of five stages within the winery:

1. Harvesting

The process begins with harvesting the grapes from the vineyard at the exact moment they have reached their desired maturity, providing the raw material for winemaking.

2. Crushing and Pressing

The grapes are transported to the winery where they are broken open (crushing) to release their juice (must).

• For white wines: The grapes are pressed immediately so the juice is separated from the skins, preventing any color extraction.

• For red wines: The juice is left in contact with the skins for several days (maceration) to extract the deep red color and tannins.

3. Alcoholic Fermentation

This is the heart of winemaking. Under the influence of yeasts (either indigenous or selected), the sugars naturally present in the must are converted into alcohol and carbon dioxide. This process is temperature-controlled and can take place in open or closed vats, depending on the wine style.

4. Aging

After fermentation, the wine needs time to develop and balance. Aging can last from a few months to several years. Winemakers choose between:

• Wooden (oak) barrels: To add complexity, body, and aromas (such as vanilla and spices).

• Stainless steel tanks: To preserve the clean, fruity, and fresh character of the grape variety.

5. Filtration and Bottling

In the final stage, the wine is stabilized and, if necessary, carefully filtered to remove any sediments and particles, ensuring its clarity. It is then directed to the bottling line, sealed, and becomes ready for the market or for further aging in the bottle.

Part 2: Specialization in the Wine Zone of Dafnes

When this process takes place in the historic zone of Dafnes Heraklion (PDO Dafnes), it is fully tailored to the specific needs of the region’s two major indigenous grape varieties:

Winemaking of Vidiano in Dafnes

Vidiano requires extremely careful handling during the first stages of winemaking to protect its delicate character:

• Protection against oxidation: During crushing and immediate pressing, the must is protected from oxygen exposure (often using inert gases) so that the sensitive aromas of stone fruits and citruses are not lost.

• Fermentation control: Fermentation takes place at controlled, low temperatures in stainless steel tanks to emphasize its vibrant acidity. Some producers choose to age a portion of the wine in barrels, highlighting the rich and creamy structure that this variety can develop in the Dafnes region.

Winemaking of Liatiko in Dafnes

Liatiko, as the flagship red PDO variety of the zone, has its own unique winemaking requirements:

• • The challenge of color: Liatiko naturally has a low concentration of coloring pigments in its skins. For this reason, the maceration stage during crushing requires great mastery and precise time control to achieve its characteristic, elegant ruby color without extracting aggressive tannins.

  • Patient aging: Due to its delicate nature, Liatiko thrives when aged in older (used) oak barrels. This helps its tannins soften and allows the typical aromas of the variety—such as dried red fruits, sweet spices, and Cretan herbs—to fully develop.
