This may seem evident to some, but even so, many vignerons ignore the fact that “everything depends on the vine.”

It is wishful thinking to suppose that you can significantly improve the intrinsic quality of the juice or of the wines during the vinification, or later: one can only try to retain the potential of the grapes. To go further in the search for the expression of aromas, fruit and terroir, we have adopted, in addition to organic culture, the principles of biodynamic agriculture.

The special attention given to the soil and the vines.

“It is important to understand the nature of the different soils on which the vines grow, in order to tend them and to work properly.”

We never use synthetic fungicides, insecticides or weed-killers because chemical products destroy the secret life in the soil and alter the microbial activity, leading to compacting of the soil, to the detriment of the roots of the vines.
It is vital to improve the activity and the diversity of the microbial life by digging and ploughing, as well as spreading organic compost. The organic struggle is based on preventative action.
The use of tisanes (*horsetail, osier, *stinging nettle) increases the effectiveness of the treatments and is beneficial to the vine.
The spreading of *Marie Thun cow dung compost in autumn and spring improves and accelerates the humidification of the organic matter.
The use in spring of *product 500 or *product 500P (cow dung that has been buried in cow horns over winter) helps the soil to revive and to become restructured, thus improving its breathing and fermenting functions.
Lastly, before the flowering of the vine, the use of *product 501 (silica of cow’s horn) helps the development of photosynthesis and improves the structure of the vines.
Also, we help the young vines to cut the little roots near the surface, so that the vine forces its main roots deeper into the soil. The management of the weeds (wrongly called mauvaises herbes) is also done by hoeing, so that they are not in competition with the vines.

*Specific to biodynamic agriculture. For more information see the website BIODYVIN on the last page.

The control of vegetation and yield

For the best results, the vines must be in balance to and be able to spread and grow in their natural rhythm but not to excess, in soil that is full of life. Thus, the plant will perform at its best.
The best solution for controlling yield is sharp pruning in winter that naturally reduces the eventual number of bunches of grapes on the vine.
Vigour is closely linked to fertility and therefore yield.
When we plant new vines we use cuttings with low vigour, in general, mainly from sélections massales, which increase the biodiversity, in contrast with clones.
The density of planting must be high (between 5500 and 7800 vines per hectare). This makes each vine compete with its neighbours and encourages its roots to search much deeper for water and nutriment and to discover all the complexity of its terroir.

These methods contribute to the preservation of the environment and the perpetuity of the vignoble.
