Where is Jerez Superior primarily located?

Jerez Superior primarily refers to vineyards that are registered as part of the Denominación de Origen (DO) in various towns throughout the Jerez region. This designation encompasses a broader area than just the immediate vicinity of Jerez de la Frontera, allowing for a diverse range of vineyards located in specific, traditionally recognized towns around the region. This system was established to ensure the quality and authenticity of the wines produced, promoting a sense of place that is integral to Sherry production.

The other choices do not accurately capture the essence of Jerez Superior. For instance, while some vineyards might be located in specific geographic areas, they are not strictly limited to the northern parts of Jerez or any single coastal or mountainous area. Instead, the focus on various towns emphasizes the regional aspect of production under the DO regulations, highlighting the importance of diverse terroirs and viticultural practices found across the Jerez region.
