ROOTSTOCK AND MERCIER SOURCING POLICY
 Mercier has started in the 90’s planting its own foundation mother blocks in order to improve the sanitary quality and the traceability of its vines. Today we have under our direct control more than 270 hectares of certified category scion wood and rootstock vineyards.

 Mercier focuses with the greatest care on the sanitary quality of its mother blocks vineyards. Each year all these vineyards are visually checked and one third is virus controlled by our NOVATECH laboratory.
