What is a significant characteristic of the Clos de Tart vineyard?

The Clos de Tart vineyard is recognized as a monopole vineyard, meaning that it is solely owned and managed by a single entity. This characteristic is significant because it allows for consistent management practices and quality control over the entire vineyard's production, ensuring that the wines reflect the unique terroir and style associated with Clos de Tart. Monopole vineyards are relatively rare in Burgundy, which adds to their prestige and the desirability of the wines produced from them.

In the context of the other options, it’s important to note that Clos de Tart is renowned for producing red wine, primarily from Pinot Noir grapes, rather than white wine. The elevation aspect may vary, but it’s not a defining characteristic of this specific vineyard compared to its monopole status. Lastly, while vineyard age can influence wine quality, Clos de Tart's reputation does not hinge on being sourced entirely from young vines.
