What soil type is typical in Mendoza’s premium valleys and aids drainage?

Mendoza’s premium valleys rely on soils that drain quickly so vines don’t sit in moisture between irrigation cycles. The typical soil is well-drained alluvial material deposited by rivers, often with a rocky subsoil. This texture lets excess water escape, reduces root rot risk, and concentrates heat to help grape ripening in the hot, dry valley climate. The rocky components can also limit vigor, encouraging deeper rooting and more developed flavors. Heavy clay would hold too much water and risk poor aeration, so it’s not ideal for these sites. Limestone bedrock with only a shallow topsoil isn’t the defining feature of the premium valley soils, though calcareous soils can occur elsewhere. Peat-rich soils would imply waterlogging, which doesn’t match Mendoza’s arid vineyard conditions.
