Gruner Veltliner

 

Grüner Veltliner is an aromatically shy variety that is native to Austria and produces wines that are focused on its zippy acidity and delicate primary aromatics.

The wines may show botrytized notes (saffron, ginger, added texture) in the Wachau (Austria) for example when the grapes are harvested late, at smaragd ripeness level. Grüner Veltliner are rarely put in contact with new oak and the main winemaking contribution are from yeast extract and lees contact. A low level of dissolved carbon dioxide is likely especially at entry level.

Sparkling wines from Grüner Veltliner are possible. The wines are primarily made to be drunk young when they are fresh and vibrant but the high acidity and extract of the variety are good indicator of ageability.

Reference regions are in Austria: Wachau, Kamptal, Kremstal, Weinvertel. Laterals include Furmint, Assyrtiko, Pinot Gris, Riesling, and Chenin Blanc. Its recent trendiness, due to its ability to pair well with food, has helped seen this variety blossom in regions outside Austria.

Grape cluster: medium to very large; medium density; conical; shouldered, with large round to oval berries; greenish-yellow, to foxy-yellow on the sun-exposed side.

Ripening time: mid-season

Conditions:

It grows especially well in deep loam soils, not drought resistant, is sensitive during flowering, and is susceptible to peronospora, Roter Brenner (Pseudopezicula tracheiphila) and chlorosis

Clone available:

Pinot gris

Nicolas Quillé 

Pinot gris is a mildly aromatic variety that can be relatively neutral especially at high yields and in warmer regions. It makes a quaffable white wine that is weighty from its lack of acidity accentuated by the potential for residual sugars especially in Alsace. Because its skin is pink, it is often rich in phenolics providing a little color to the wine and a hint of astringency and/or bitterness which the residual sugar helps to balance. 

Pinot gris are not very ageable and are mostly made to be drunk young. The only exception to this rule are Alsatian Pinot Gris that have significant residual sugar and that develop exquisite nutty tertiary aromatics. Alsatian Pinot gris are vastly more complex and concentrated and are in a class apart from anyone else in the world. 

Classic regions for Pinot Gris include Alsace, Italy (Alto Adige, Friuli, Venezia Giulia), Oregon as well as Marlborough & Mornington. Laterals to Pinot Gris include many Italian white grapes such as Verdicchio, Vernaccia, Arneis, Cataratto, Trebbiano, Fiano, Greco, Falanghina and also Picpoul, Chenin Blanc and Chardonnay.
