Winter is the pruning season, but it’s also the time for replanting any vines which are unhealthy or have become too old. For the Nacional parcel, this stage requires a specific technique, known as “mass selection”, to be used.
Because the Nacional vines are not grafted, which makes them an extreme rarity, the replanted stocks must be from the same parcel. We therefore pick out a shoot from one of the finest looking stocks on the plot, and plant it directly into the ground. It will then take root and will itself become a vine stock, ungrafted and directly rooted in the earth, without any intermediate rootstock. Thus it is that, year in year out, we preserve the singularity of the vines from this terroir which is quite unique in the world.
