The San José sub region is located withing the Metropolitan wine region of the Uruguay wine country, one of the smallest countries of South America, sharing this area with the Canelones and Montevideo wine regions. Its landscape is dominated by rolling hills, on which the vineyards extend. This allows the vines to absorb the amount of sun they need for the grapes to reach an ideal ripening point. The hills that define the unique topography of the region serve as natural barriers against the winds that can affect the region.

The San José sub region enjoys a humid subropical climate, with enough rainfall through the year. Cool breezes drift inland, providing relief from the summer heat and contributing to the slow and even ripening of the grapes.

Regarding the soils, fertile clay-loam soils predominate in San José. This provides winegrowers with an excellent background for vine growing, thanks to the great water retention capacity of these soils.

The gentle climate of this region, combined with the unique characteristics of the soil, allows to develop high-quality grapes that are the foundation of the region's esteemed wines.

The San José sub-region features a humid subtropical climate that defines its unique landscape. This type of climate, denoted as Cfa by the Köppen climate classification, brings moderate to warm temperatures year-round, which is ideal for grape growing. Throughout the year, the area receives enough rainfall, even during the drier months, ensuring that the vineyards remain hydrated.

The influence of three surrounding rivers and of the Atlantic Ocean moderates the climate, softening extreme temperatures that otherwise could harm the vines. This allows for a longer growing season, providing vine growers with the stability needed to plan for optimal harvests. Summers in San José are warm, promoting vigorous vine growth without decreasing the quality of the grapes, while the mild winters help to prevent frost damage.

The high nutrient content of these soils is beneficial for the grapes, allowing to produce wines with richer and robust flavors.
Schist Soils: Found on the slopes of Sierra de Mahoma, schist soils have a great drainage and less fertility than clay-loam. These soils force the vines to develop deep root systems, stressing them enough to obtain grapes with concentrated flavors.
