Süße and Säure | DiePresse.com

The climate heating warms the smell and aroma of the different types of wine. A way has been found to use the actual data and the strict Vorschrift for quality wines.

Whoever is from the Austrian Wine Industry Association this week will have a small amount of mixtures in the course of 2024, with a very powerful wine reform. With the help of the Monat früher as gewöhnlich begun – “with a harmonious Zucker-Säure-Verhältnis zu erhalten”, who is he. The best records are in the acidity of the trauben and the acidity sinks. It changes the taste and aroma of traditional wines.

Jede Rebsorte has a climbing star, which is optimal. The best results are those “Huglin-Zahl” (Wärmesumme): Grüner Veltliner z. B. gellingt is best with a Huglin-Zahl zwischen 1700 and 1800, Cabernet Sauvignon zwischen 1900 and 2000, Syrah zwischen 2100 and 2200 usw.

The extensive climate walking changes the conditions for different lifestyles. Während z. B. das Kamptal in the 1960s was now for a white war, he became a beautiful Rotweine keltert – for a softer white range it would take longer and longer. It is also possible to enjoy fresh wine in the regions that are grown – it is common to have fresh wine in the Norddeutschland or in the Waldviertel area (so who knows how to keep the climate optimal). In Burgenland the Rotweine would be reformed, as is typical for Spain or South America.

Das Klima is freilich nur a “Zutat”, which is very bad. B. der Boden, the art of culture, from the Ausbau im Keller usw. Dennoch would like to know that the traditional winemaking regions provide major changes. Gleichzeitig regarding the quality of wine that is certified as “geschützte Ursprungsbezeichnungen” (Protected Designation of Origin, PDO) during EU registration is very strict. Früher or später would be the faktische Entwicklung with die stars Vorschrifts kollidieren.

A research group with Simon Tscholl (Eurac Research Bozen, at the University of Innsbruck) has now systematically investigated this tension field in 1085 BOB winegrowing regions in all of Europe. It is possible that the climate development with the changed regions (insightful know-how, financing possibilities, water availability, mechanisms, etc.) combined and a large amount of vulnerability (vulnerabilities) has been identified. The winegrowing regions in central Spain, the Italian Adriatic coasts and Eastern Europe (Ungarnia, Romania and Bulgaria) are among the vulnerable. A small problem fell for France, Portugal and – surprisingly – South Africa in extremis (Nature Communication, 24.7.).

The situation is visible in Österreich: I am vulnerable in the Weinbaureregionen Neusiedlersee, Leithaberg and Carnuntum. Mittlere Verwundbarkeit weisen etwa das Weinviertel, Wien, das Traisental or die Südost- und Südsteiermark auf. It is good to know that in the inner alpines it is Weinbauregionen – in the Wachau. Cheers!
