Grüner Veltliner is an Austrian white wine grape variety known for its citrus aromas of lemon peel and grapefruit, complemented by stone fruit and vegetal notes, and a hint of white pepper. The variety is typically split into two styles: a lighter, fresher style from the Weinviertel region, and a spicier, weightier style from the warmer Wachau, Kremstal, and Kamptal regions. These wines are richly textured and well structured, and require several years in bottle before reaching maturity. The name Grüner Veltliner is often shortened to "Gru-Ve" or "Groovy" and refers to the grape's yellow-green berries and green-pepper character. The grape is grown extensively in Austria, Slovenia and the Czech Republic, and to a lesser extent in Northern Italy, New Zealand, Australia and the United States.
