What vine training method is specifically used in Santorini for protection against wind?

Basket shape training, known as "kouloura," is a vine training method specifically utilized in Santorini to protect the vines from strong winds, which are common on the island. This technique involves pruning the vine into a low, basket-like shape that allows the foliage to be closer to the ground. By doing so, the leaves and grapes are sheltered from the wind, reducing the risk of damage and desiccation. The structure also helps retain moisture around the vine, which is crucial in the arid climate of Santorini.

In contrast, high trellising techniques would expose the vines to wind rather than protect them, making them unsuitable for this environment. Flat training on the ground might not provide adequate air circulation and could lead to difficulties during harvest or in terms of disease management. Vertical shooting positioning, while effective for certain climates and growing conditions, does not provide the necessary wind protection that the basket shape method does in the unique conditions of Santorini.
