To breed new grape varieties that are perfectly adapted to climate change and to different regions in europe, Valentin Blattner works with a lot of different partners in Spain, France, Germany and Switzerland. In the following videos, the international breeding project is presented and explained.
Valentin Blattner explains, how a resilient vineyard in an intact ecological system can provide a good crop with a reduced amount of working hours.
Valentin Blattner explains how you breed new grape varieties to get more resistant plants with better features.
Valentin Blattner explains the importance of multiple resistant genes in a new grape variety. More videos (with subtitles in various languages):
Valentin Blattner and Josep Maria Albet i Noya work together to breed new resistant varieties in Penedès, Catalonia.
In Neustadt, tests are being carried out to see how resistant the new varieties are to the powdery mildew fungus.
In a seedling field, Valentin Blattner plants thousands of seedlings every year to see how resistant they are.
To select the best plants, they are exposed to high disease pressure: Only those with the best resistance survive.
Some newly bred vines are immune to downy and powdery mildew and have great potential for a new grape variety.
To ensure long-lasting resistance of the new varieties, as many resistance mechanisms as possible are combined.
In Spain, new, resistant grape varieties are still officially banned. Josep Maria Albet i Noya wants to change this.
Resistant grape varieties are not only needed in northern countries: they also bring advantages in southern Europe.
In order to test newly bred varieties for their taste, Josep Maria Albet i Noya vinifies the grapes on a small scale.
In Priorat, new grape varieties are vinified and sensory evaluated in a professional setting.
