Sommer is an Austrian winery in Burgenland, the easternmost wine region of Weinland. The estate focuses on Grüner Veltliner, Austria's signature white variety—a grape known for its bright acidity, mineral precision, and herbaceous character. The winery's core lineup includes a flagship Grüner Veltliner, the Ried Halser Grüner Veltliner, and Grüner Veltliner Klassik. Wine Enthusiast and Wine Advocate have both assessed the portfolio. Burgenland's continental climate and diverse soils produce whites of clarity and structure, and Sommer's expressions reflect that terroir-driven approach. The winery's commitment to the variety demonstrates the depth possible within a single grape across different vineyard sites and styles.
