The Wachau has 1,390 hectares of vines, planted in soils of weathered primary rock, sand and loess. In addition to Riesling and Grüner Veltliner, other typically Austrian varieties grown here include Neuburger and Gelber Muskateller. The "Vinea Wachau Nobilis Districtus" is the local association to which most local winemakers belong and which defines the classification of Wachau wines - Steinfeder, Federspiel and Smaragd.
The geology in the Wachau is based around soils derived from primary rock, known here as urgestein. This is composed largely of granite, gneiss or mica-schist, although the composition varies somewhat throughout the region. With slate in the west around Spitz, more loam in around Weissenkirchen in the central Wachau and then in the east around Krems, the gateway to the Kremstal, some limestone.
The climate in the Wachau varies quite significantly over short distances and is quite interesting. At the western end around Spitz, it is cooler, as here cold winds can blow down from the mountains, so the wines are more fragile and have more of a nervy steely character than in the east. In the east where the land is flatter, the climate is starting to become affected by the Pannonian climate of the great Hungarian Putsch near the Austrian/Hungarian border, around the Neusiedlersee this is much more pronounced with bitterly cold winters and hot arid summers.
Everywhere in the Wachau the climate is moderated by the proximity of the river, although it can be very dry in summer and limited irrigation is permitted. Because of the differences in the climate the harvest date also varies, being a bit earlier in the east than around Spitz.
The Loibenberg and Steinertal hill is the hottest/most sun exposed vineyard in the Wachau - you can tell!
The region blooms during the apricot season in the springtime (Apricot or Marillen brandy is another regional speciality) and this is a wonderful time to visit
