"The grapes are ripe again as they were in the past. The vine finishes its cycle quite normally, without heat strokes neither on the leaves, nor on the bunch "

"In the middle of a drought the impact of Ombrea is obvious. Underneath the solutions, you have a plant that is very green and resourceful. Outside, the plant would dry out even with watering."

This project is our first demonstrator on vines made from one of the most represented grape varieties, Grenache. This grape variety is strongly concerned by problems of decline on a national scale. The objective of climate protection is therefore to perpetuate this emblematic crop of Provence while maintaining the yield and quality of the wine produced

"The results obtained from this demonstrator on a wine grape variety that is emblematic of Provence confirm the assumptions we made about climate protection applied to vines.

The benefits of the Ombrea solution

Ensuring access to light during key phases of development

Reducing frost related risks

Guaranting an adequate time course of the maturation process

Protecting the vine from thermal, hydric and oxidative stress

Guaranting cold accumulation

Ensuring the good progress of the carbon and nitrogen reserve

WITNESS ZONE

Agronomic results

Yield

Higher yields under shade in number of clusters, cluster weight and weight per vine

Quality

At equivalent TAV: more acidity under shade (pronounced effect on malic acid)

Harvest

Staggering of the harvests under shade by 5 to 9 days and advancement of 1 year on the date of the first harvest for the controlled plot

Effects on weather conditions

Air temperature

51% reduction in hours above 35°C

Soil temperature

Systematically lower under controlled shading

Sunshine

66% reduction in the amount of sunlight that can damage crops

Water stress

A 32% reduction in atmospheric water stress periods
