|”A great terroir wine dawns in a vineyard, outcome of a soil, a climate but most of all of daily respectful and sound practices.”
Plowing one in two vine row permits to push the ground against the vine stocks to protect them from cold temperatures and humidity during the winter. It also permits to control the vegetation without using chemicals.
The vine pruning is done during the coldest months of the year. The vine is resting, and the sap is stored into the roots. The winegrower selects two shoots that are going to hold the branches and the grapes for the next vintage. The cut wood is removed from the palissage and crushed; the ground’s microorganisms will then decompose it into assimilable minerals for the vine.
We shape on each vine stock two arches which correspond to the two sticks chosen during the pruning. The bend slows down the sap and permits to the branches to develop homogeneously. As a climbing plant, the vine would tend to favor bud grouth at the ends.
The spring’s plowing is done to withdraw the land accumulated around the vine stocks which don’t fear the cold températures anymore. The most superficial vine roots are also cut to encourage a deeper rooting and a better mineral expression for the wines.
The disbudding permits to remove unnecessary vegetation. Sometimes, a single bud can gives two branches, what favors vegetation overgrowth, humidity and diseases (powdery mildew, mildew and rot). Limiting the yield will also give better aromatic concentrations for the grape and therefore for the wine.
The trellising, manual or mechanic, permits to guide the branches’ growth by maintaining them on a plan. The vegetation, perfectly distributed, will catch a maximum of light and protect the grapes from sunburns.
Mechanic mowing helps to control the grass growing in the non-plowed rows. The plowed-rows are regularly scratched to remove unwanted vegetation.
Leaf-stripping allows a better aeration of the trellis system. A lack of ventilation would encourage the development grape rot. The leaf-stripping also permits bring light to the less exposed grapes (often on the north side of the rows).
