What are PGI wines known as in Spain?

PGI wines in Spain are known as "Vino de la Tierra." This classification indicates that the wine is produced in a specific geographic area and adheres to certain quality standards that go beyond basic table wines. Vino de la Tierra wines must meet regional production criteria and can encompass a wide variety of styles and grape varieties, allowing winemakers more flexibility compared to the stricter DO (Denominación de Origen) regulations.

In contrast, Vino de Calidad refers to a lesser designation that is sometimes used but is not as commonly recognized as Vino de la Tierra. Vinos de Pago represent wines made from specific single estates with higher quality standards, while Vino de Mesa denotes basic table wines that do not necessarily adhere to specific geographic designations or quality standards.
