Spitzerberg
One can perhaps picture the Spitzerberg as a reef, with the primeval ocean breaking upon its rocks for millions of years. Because of this, the Spitzerberg is covered with a thick layer of limestone, which comes from the ‘middle ages’ of geology. The sandy ground retains little in the way of water, and the mount – some 300 metres in elevation – always lies open to strong winds and high temperatures; there is no mistaking the expressive nature of grapes grown on the Spitzerberg. The extreme conditions yield marvellously aromatic wines with complexity and depth, finely woven filigreed texture and a refreshing framework of acidity.

On the slope of the Spitzerberg, we find thick layers of limestone today — in some places stony, in others sandy. In every case, the soils are very lean and very dry, and the wines that grow here are characterised by tightly woven finesse and a refreshing backbone of acidity.
The wind
No wonder, then, that the Spitzerberg is a destination of choice for gliders and sailplanes. There are hot and dry air masses that flow continually from the enormous plain to the south, bound for the Danube River Valley. The Spitzerberg, which lies smack in the middle of this corridor between the Leitha Range (Alps) and the Hundsheimer Hills (Lesser Carpathians), presents itself as a barrier upon which the warm air currents rise and collect. These updrafts provide pleasure on a daily basis to innumerable unpowered aircraft, which soar and hover silently above the Spitzerberg.
For the vines, these warm air currents provide a blessing and pose a challenge at the same time. On the one hand, constant winds dry up all moisture in no time at all, so that there is hardly any danger of fungal infection on the Spitzerberg. And on the other hand, the hot and dry conditions put the vines under significant stress, threatening their very existence. Any growth of vegetation is minimal – the plants concentrate their entire energy on the modest growth of fruit. This makes wines from the Spitzerberg expressive in an unmistakeable way.
Temperature
The exposed situation drives conditions of the continental climate to extremes. During the winter months, an icy wind whistles around the hillsides. In July and August, the temperatures will often climb toward forty degrees, but the nights in late summer and autumn are quite cool. This enables the clusters to develop an advanced degree of ripeness, but thanks to the meagre amounts of water involved, sugar production (and with it the production of alcohol) remains moderate. And the cool autumn temperatures preserve refreshing acidity.
Precipitation
The annual average rainfall is around 400 millimetres – this causes the grapevines on the Spitzerberg to exist right on the edge of survival. Most of the rain falls in May or June, and often takes the form of violent thunderstorms and heavy downpours. The vines must nourish themselves for the entire summer from these. The most important period for the quality of the grapes is in the last weeks before the harvest. This is when one notices the greatest influence of climate change. While thirty years ago the harvest began in mid-October on the Spitzerberg, the warming of the world finds the grapes now ripe around end of September.
Gebietswein – Ortswein – Erste Lagen
The slope of the Spitzerberg comprises around 100 hectares of vineyard area, stretching across several tiers of terrain. The parcels at the foot of the hill have deeper soils with more humus, allowing them to retain more moisture. The higher one goes, the more sparse and stony the soils become, and the more expressive the wines are.
We cultivate just under twelve hectares of vineyards, divided into more than 30 individual parcels. This fragmentation has the advantage that, over the years, we have been able to gain a particularly wide range of experience and identify the quality potential of each individual site in great detail.
Carnuntum
For our CARNUNTUM regional wine, we use grapes from young vines as well as from parcels located at lower elevations.
