Which grape variety is NOT considered a key white grape variety in Austria?

Chardonnay is not considered a key white grape variety in Austria. The country is primarily known for its indigenous grape varieties, notably Grüner Veltliner and Welschriesling, which are staples in the Austrian wine industry. Grüner Veltliner, in particular, is the most widely planted grape and is renowned for its versatility and the distinctively spicy, mineral qualities it can exhibit. Welschriesling is also significant and plays a vital role in the country’s wine production, particularly in the regions of Burgenland and Styria.

While Riesling is widely respected and cultivated in Austria, particularly in regions like the Wachau and Kamptal, it is not as predominant as the indigenous varieties mentioned. Chardonnay, although it is grown in Austria, does not hold the same level of importance historically or commercially when compared to the native grape varieties. Thus, Chardonnay does not fit into the category of key white grape varieties that define Austrian white wine production.
