We want our vines to put down a deep and extensive network of roots in order to absorb their character from the soil chosen for them. On these steep slopes the water run off is high and the soils are less weathered with abundant fragments of parent rock material in the subsoil. The soil material between the rock fragments is also more silty than clayish. These soils belong to the Glenrosa soil form. They are low in clay and with their high rock content will stay loose and pliable after ripping.
Vines hate to have their roots in water so soil forms with clay are to be avoided.
Glenrosa is one of the best soils for growing vines. Glenrosa soils were found to cover a vast part of the farm. That is one reason we chose the farm. These Glenrosas are further divided in 6 variations. The former group retain water less and are suitable for vigorous growing and early wine grape cultivars.
