Determine the qualitative potential of your grapes

Vivelys has developed a set of indicators for defining the potential of each vineyard parcel, based on factors such as grape ripening.

 

Harvest planning

Vivelys supports producers by helping to define their harvest strategy based on targeted wine profiles, which are translated into grape profiles.

Our solutions

Xilem

The decision-making tool Xilem tracks the vine’s hydric activity in order to :

  • Secure the target grape profile, the resulting wine quality and yield;
  • Manage suitable and controlled irrigation as an immediate response to hydric stress (in areas that can be irrigated);
  • Drive a medium-term vineyard management strategy – tillage, vine density, fertilisation, operations during the vine’s growth, etc. - (in areas that can or cannot be irrigated).

The tool provides a clear indicator of daily hydric activity based on the difference between the temperature of the leaves and that of the air.
This temperature difference depends on the vine’s level of transpiration.

Dyostem

Physiological monitoring of grape ripening and predictive determination of the grape profile.

Dyostem® enables growers to sort the grapes into different homogenous categories according to their potential, ripeness and ability to produce a specific wine profile. It offers an exclusive way to measure grape potential in each parcel, given the vintage conditions. It can also be used to define the optimum harvest date depending on the targeted wine profile.

Based on the grape-profile concept, Dyostem® relies on physiological markers of vine behaviour : sugar loading and changes in the colour of the fruit.

Sugar loading is an indicator of how the plant is faring during ripening. It is directly related to its photosynthetic activity, the balance and the physiological condition of the vine. In contrast, the changing colour of the fruit is used for white grape varieties. This is a marker of the microclimate of the fruit, which has a major impact on the aromatic typicality of the final wine.

This specific monitoring of the fruit ripening process provides information on how the vine behaves in its terroir and in response to vintage conditions. It is used to inform decisions on harvest.

Consulting

GRAPE PROFILE AUDIT
The grape profile audit meets two key objectives :

  • Quantify the proportions of grapes with varying levels of potential across the vineyard,
  • Qualify the positioning of the harvest in terms of grape profile and analyse its suitability to meet production targets

We use the Dyostem® decision-making tool to identify grape potential. Based on the grape- profile concept, it enables growers to *sort the grapes into different homogenous categories* according to their potential, ripeness and ability to produce a specific wine profile.

 

 

HARVEST MANAGEMENT SERVICE

This service involves planning harvests based on production targets, parcel potential and logistical constraints.
Organisational and logistical constraints affect the extent to which grape potential is realised in the resulting wine. Identifying grape profiles and predicting how they will change enable winemakers to take objective decisions and make compromises where necessary. The ability to generate harvest batches with recognised and consistent characteristics means that the technical choices associated with vinification procedures can be adapted.
