Rainer Wess Wachauer Riesling 2015
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.
