It’s Sauvignon Blanc—not Grüner Veltliner—that’s the star of the show in Austria’s Südsteiermark DAC, a historic winegrowing region in the country’s southern state of Styria that has evolved rapidly over the last thirty years. The variety is grown at high elevation in all five of Südsteiermark’s sub regions and on steep slopes that rival those of the Mosel.
Of them, Kitzeck-Sausal has the highest and steepest. With its elevation exceeding 2,100 feet and more than 100% slope, it is also the highest-steepest Sauvignon Blanc winegrowing region in the world. (The world’s steepest vineyard is the Bremmer Calmont located on the Mosel which has a 210% slope and sits at 950 feet.)
Südsteiermark’s transition from producing sweet, classically-styled wines to incredibly high-quality dry wines from Sauvignon Blanc began more than 30 years ago with winegrowers Erich Polz, Willi Sattler, and Manfred Tement. In 1993 the wineries Sattlerhof, Tement, Polz, Prünte, Winkler-Hermaden, Lackner-Tinnacher and Gross established the Steirische Klassik, a precursor of the producer group now known as Steirische Terroirs & Klassik Weinguter aka the STK.
Similar in many respects to Germany’s VDP, the STK in 2006 established guidelines for further classifying the region’s Rieden (registered single vineyards). In doing so they relied on historic vineyard names taken from the oldest maps of Styria many of which have been noted on labels since the 1980s. The work of the 12 producer members who now form the STK was instrumental in the recent elevation of Südsteiermark to a Controlled District of Austria (DAC) region in 2018.
STK producers Gross, Lackner-Tinnacher, Wolfgang Maitz, Polz, Erwin Sabathi, Hannes Sabathi, Sattlerhof, Tement, and Wohlmuth are located in Südsteiermark DAC. Producers Frauwallner, Winkler-Hermaden and Neumeister are located to the east of Südsteiermark in the neighboring region of Vulkandland Steiermark where Sauvignon Blanc is grown in all three subregions.
In addition to the regional, village and riede wines produced in Südsteiermark and Vulkanland, the STK has further designated single-vineyard sites as Erste STK for the production of STK Premier Cru wines and Grosse STK for STK Grand Cru-designated wines. The criteria that define Erste and Grosse sites and wines relies on both vineyard and winemaking factors. Most notably, the requirement for hand harvesting which given the extremely sloped vineyards is practically a given. Sites must be sloped – many exceed 45% and approach 90% – and run from east to west with a favorable mesoclimate.
Styria can be roughly divided into a northern mountain region, which is not suited for wine growing, an the southern region which has a mixed Alpine-Mediterranean climate in the higher-elevation western regions and a Pannonian-Continental climate in the lower eastern region. Südsteiermark DAC is defined as having a humid Alpine (also referred to as Illyrian)-Mediterranean climate with marked diurnal shift (~25-30°C during the day and 8-20°C at night) and warm, amphitheater-like sites that sit above the fog line where they are protected from overnight frost that occurs in the spring. Cool rain moderates summer temperatures but hail poses a risk during the long growing season that is ideally suited for achieving balanced ripeness in Sauvignon Blanc.
Although winegrowing practices are not universal, there are a number of best practices like the use of mechanization that has been specialized over the last decade to manage ground cover. For example, permanent in-row ground covers are often rolled instead of mowed to preserve habitat. Austria recently passed a law prohibiting the use of the synthetic herbicide Glyphosate in vineyards and winegrowing in harmony with nature is emphasized.
Netting is used to protect the vines from hail and to restrict the canopy. Stony soils also help manage the requirement for low yields of this typically high-yielding variety. Clonal selection in the vineyards is more or less homogenous as massal selection has been the primary source of plant material since Sauvignon Blanc was introduced to Südsteiermark by Archduke Johann in the early 1800s. Vines are quite healthy with Eutypa being the only common virus.
Made with the Intention to Age
In addition to their unique terroirs, specified minimums for vine age and extremely low yields, STK Premier Cru and Grand Cru wines are subject to lengthy bottle conditioning and aging requirements. STK Premier Cru wines are released no earlier than September twelve months post-harvest and must demonstrate five years aging potential while Grosse STK Grand Cru wines are cellared for eighteen months and must have the ability to age gracefully for ten years. The resulting quality and style of these elegant wines makes them some the longest-lived of their kind.
Within the STK there’s been an intentional effort by producers to move beyond fruit forward-styles toward smokier, flinty wines showing complex fruit, spices like ginger and more evolved fruit like grilled pineapple.
As they rely on pristine fruit—typically with no evidence of Botrytis—winemaking practices include malolactic conversion, native yeast fermentation, extended lees aging and very low amounts of sulfur. Fermenting and aging typically takes place in large-format 600-liter
Slavonian oak foudre known as a “startin.” Screwcap and glass closures are commonplace although some producers including Polz have returned to using natural cork.
NAVIGATING THE SUBREGIONS Given this general consensus with regard to winemaking practices, wines that hail from the STK Erste and Grosse-designate single vineyards are differentiated more by subregion than by winemaking. We’ll navigate the region beginning in the north then move south and finally east to Vulkanland.
KITZEC-SAUSAL Kitzeck-Sausal is the northern-most subregion where single-vineyards sites were on record as early as 1322. Vines are planted to elevations of 1,250 to 2,130 feet on slopes that can exceed 90%. Soils are very low vigor, weathered slate and schist that retain heat.

Wohlmuth.
