Yes, some raisins are dried directly on the vine. This method is known as "Dried on the Vine" (DOV) and is used for certain types of raisins.
While many raisins are dried after being harvested and placed on trays or paper, the DOV method allows the grapes to dry naturally while still attached to the vine. This process is typically achieved by cutting the canes (the arms of the vine that bear the grapes) but leaving the fruit clusters hanging. The grapes then dry in the vineyard's climate.
Challenges of Drying Raisins on the Vine
Although drying on the vine can produce high-quality raisins, the process is subject to environmental factors that require careful management. According to information presented in videos about how dried on the vine raisins are grown and harvested, potential issues during this drying process include:
- Exposure to dust and pests: As the grapes hang and dry, they can be exposed to airborne dust and various insects or pests in the field.
- Caramelization from direct sunlight: Intense, direct sunlight can cause the sugars in the grapes to caramelize, potentially affecting the texture and flavor of the finished raisins.
- Mold due to rain: If rain occurs during the drying period, the moisture can lead to the development of mold on the drying grapes.
Growers using the DOV method must monitor weather conditions and vineyard health closely to mitigate these risks and ensure a successful harvest of quality raisins.
