Summerer produces wines from Kamptal, a valley in Austria's Niederösterreich region known for mineral-driven whites. The winery's focus centers on Grüner Veltliner and Riesling, varieties that thrive in this cool climate. The Reserve Grüner Veltliner Käferberg and Reserve Grüner Veltliner Schenken represent the winery's work with Grüner Veltliner across distinct vineyard sites, while the Steinmassl Langenlois Riesling draws from the region's limestone soils. These wines have been assessed by Wine Enthusiast, Falstaff, and Wine Spectator.
