What defines the tejon sub variety of albariza soil?

The tejon sub-variety of albariza soil is characterized primarily by the presence of a hard rock of almost pure limestone found deep in the soil profile. This specific geological feature contributes to the soil's unique properties, which are crucial for viticulture, particularly for the production of high-quality sherry wines.

The presence of this limestone plays a vital role in regulating water drainage and maintaining moisture levels, which is essential for the health of the vines as it influences the development of the grapes. Additionally, the mineral content from the limestone can enhance the flavor profile of the wines produced in such soils.

While other types of soil, such as those with clay and sand mixtures, fertile topsoil, or easily workable soft soils, play roles in various agricultural settings, they do not distinctly define the tejon sub-variety of albariza soil. The unique feature of the deep limestone layer is what sets tejon apart and is significant for understanding its impact on grape growing in the Jerez region of Spain.
