When it comes to winemaking techniques associated with indigenous grape varieties, there are several unique methods that have been developed over centuries. These techniques are specific to certain grape varieties and regions, and they play a crucial role in bringing out the best qualities of these grapes. Let’s explore some of the most prominent techniques:
Hand Harvesting
One of the key techniques associated with indigenous grape varieties is hand harvesting. This traditional method involves picking grapes by hand rather than by machine. Hand harvesting allows for greater control over which grapes are selected, ensuring that only the highest quality grapes are used in the winemaking process. This is especially important for indigenous grape varieties, as they often have thinner skins and are more delicate than other varieties.
Wild Fermentation
Another unique technique associated with indigenous grape varieties is wild fermentation. This process involves allowing natural yeast present on the grape skins to initiate fermentation, rather than adding commercial yeast. Wild fermentation can result in a more complex and unique flavor profile in the finished wine, as different strains of yeast can bring out different characteristics in the grapes.
Extended Maceration
Extended maceration is a technique that involves leaving the grape skins in contact with the fermenting juice for a longer period of time than usual. This technique is often used with indigenous grape varieties that have a high tannin content, as it helps to extract more color, flavor, and tannins from the skins. Extended maceration can result in wines that are more intense and structured, with greater aging potential.
Use of Amphorae
Amphorae, large clay vessels, have been used for winemaking for thousands of years and are still used today in some regions with indigenous grape varieties. The porous nature of clay allows for gentle oxygenation of the wine during aging, which can help to soften tannins and integrate flavors. Amphorae are particularly well-suited for wines made from indigenous grape varieties, as they can highlight the unique characteristics of these grapes.
Skin Contact
Skin contact is a technique that involves fermenting white grapes with their skins still attached, rather than pressing the juice immediately. This technique is often used with indigenous grape varieties that have aromatic compounds in their skins, as it can help to extract more flavor and aromatics into the finished wine. Skin contact can result in wines that are more complex and aromatic, with a richer mouthfeel.
