Winemaker Notes
Austrian Riesling is often defined by elevated levels of dry extract thanks to a lengthy ripening period and freshness due to dramatic temperature swings between day and night. “Klaus is not a charming Riesling,” says Toni Bodenstein with a wink. Klaus is Prager’s most assertive and robust Riesling.
Riesling’s high acidity makes it one of the most versatile wines at the table. Riesling can be used to cut the fattiness of foods such as pork or sausages and can tame some saltiness. Conversely, it can highlight foods such as fish or vegetables in the same way a squeeze of lemon or a vinaigrette might.

James Suckling
Superbly cool, restrained and refined, this austere, beautiful dry riesling is a slow-burn masterpiece that's only just beginning to reveal its complex white-peach, white-tea, wild-herb and dark-berry character. Super-long and mineral finish. Drink or hold.

Robert Parker's Wine Advocate
The 2020 Ried Klaus Riesling Smaragd is deep, pure and coolish on the nose, very complex, refined and flinty. Silky, refined and elegant on the palate, this is a juicy-piquant as well as crystalline and salty, very complex and persistent Klaus of great class and style with fine tannins, stimulating bitters and firm structure. A great wine. Tasted in June 2021.

There is nice viscosity to this Riesling, with its texture caressing the palate. It might be a bit opulent, but with acidity cutting , the wine has lots of energy and intensity. It needs a bit more time to fully unravel, but glazed peach, salted caramel and blood orange flavors are giving it charm today. It can be delicious in the right setting now, but will get better in the cellar.
Riesling possesses a remarkable ability to reflect the character of wherever it is grown while still maintaining its identity. A regal variety of incredible purity and precision, this versatile grape can be just as enjoyable dry or sweet, young or old, still or sparkling and can age longer than nearly any other white variety. Somm Secret—Given how difficult it is to discern the level of sweetness in a Riesling from the label, here are some clues to find the dry ones. First, look for the world “trocken.” (“Halbtrocken” or “feinherb” mean off-dry.) Also a higher abv usually indicates a drier Riesling.
As Austria’s most prestigious wine growing region, the landscape of the Wachau is—not surprisingly—one of its most dramatic. Millions of years ago, the Danube River chiseled its way through the earth, creating steep terraces of decomposed volcanic and metamorphic rock. Harsh Ice Age winds brought deposits of ancient glacial dust and loess to the terrace’s eastern faces. Today these steep surfaces of nutrient-poor and fast draining soil are home to some of Austria’s very best sites for both Grüner Veltliner and Riesling.
Wachau is small, comprising a mere three percent of Austria’s vine surface and, considering relatively low yields, represents a miniscule proportion of total wine production. Diurnal temperature shifts in Wachau facilitate great balance of sugar and phenolic ripeness in its grapes. At night cold air from the Alps and forests in the northwest displace warm afternoon air, which gets sucked upstream along the Danube.
Its sites are actually so varied and distinct that more emphasis is going into vineyard-designated offerings even despite grape variety. Grüner Veltliner and Riesling are most prominent, but the region produces Chardonnay, Pinot Blanc (Weissburgunder), Pinot Gris, Sauvignon Blanc and Zweigelt among other local variants.
