Dominio de Valdepusa’s soil is made up of a 30 to 50 cm thick clay surface stratum resting over a two meter deep fragmented limestone subsoil formed during the cretaceous period. It is a basic soil type (pH>8), with excellent structure, porosity and drainage. In Burgundy and other prestigious wine districts it has been considered the ideal for great wine production for centuries.
Pagos de Familia Marqués de Griñón (PFMG) does everything possible to transmit the terroir characteristics to their grapes, including the soil’s physical, mineral and biological characteristics. This is achieved via the development of a deep root canopy which aids in the extraction of subsoil minerals.
The team formed by agronomist Claude Bourguignon and his wife Lydia responsible for such universally referenced vineyards as Domaine de la Romanée Conti or Domaine Leflaive in Burgunday – home of the terroir culture for over 16 centuries - advise PFMG on this matter. For example, for the new Rioja variety Graciano, planted in June 2007 at Dominio de Valdepusa, we avoided tillage replacing it with surface mulching achieved by previously sowing mown chopped barley a few weeks before the planting took place.
Other techniques which tend to make roots go deeper into the pure limestone subsoil include the use of ceptonic potting tubes which stop the roots from having contact with the first 25 cm of clay topsoil, high density plantation (5,000 vines/ha), localised drip-irrigation techniques and the elimination of surface roots. All these techniques are systematically used at Domaine de la Romanée Conti, according to Dr. Bourguignon.
