Ploder – Rosenberg grape varieties

Many of our red and white wines are fully developed, matured and bottled unmixed. In this way it is possible to produce precise wines from varieties of vine with specific characteristics such as Weissburgunder, Morillon / Chardonnay, Grauburgunder, Sauvignon Blanc, Muskateller, Grunem Veltliner, Muscaris, Blauem Zweigelt and Pinot Noir. From some selected batches we get interactions, harvested as composite rate or unmixed fermented wine brought together. We combine the characteristics of various vines and vineyards to multifaceted, multilayered Cuvee’s. Here its more to do with wine style than type of wine. And so in this way we exert our talent as a wine grower in a Demeter winery, as an attentive companion in winemaking and patient observer during the development stage. We work with the climate, soil composition and weather but above all we work with our own personal preferences. This is expressed in the increased number of wine styles from grapes, love and time as compositions of additional batches – to your enduring joy!

PIWI – grape varieties – fungus resistant grape varieties

Styria is a classic “cool climate region” with a rising annual temperature of around 11°C and precipitation levels between 800 – 1000 mm per year, whereby from May to September there is up to 70% of the annual rainfall. Mechanical cultivation of the vineyards is difficult. Frequent rainfall increases the danger of infection as well as risks doing work with machinery in steep terrain. The use of fungus resistant grape varieties considerably reduces the expenditure for plant protection and brings clear ecological benefits. It is very well possible to keep connecting sites healthy using PIWIs (fungus resistant grape varieties) with compost extracts, teas and cold extracts. This results in a clearly smaller exposure from us humans, animals, soil and plants. However, the most significant point is that the grapes grow independent of synthetic, systematic and strong influences. PIWIs are the basis of wines for a healthy body, spirit and soul!

PIWI plant protection and plant strengthening

This is a precautionary measure based on the use of cold extracts, teas, extracts of medicinal plants, rock flours, bentonite soils, baking powder, compost tea and homopathic mixtures, for curative purposes small amounts of copper and elemental sulphur. For us as a biodynamic business it is of course natural that all replacement plants, additional planting and new plantings have been carried out for many years by exclusively using PIWIs (fungus resistant grape varieties). Consideration is also given to the grafting of existing cultures which are intact and valuable.

PIWI – different varieties on Rosenberg


Severny (Seianetze Malengra X Vitis amurensis) X (Muskcat Lunel X Muscat de’ Alecandrie); Has been grown since 1947 as its own variety in Southern Russia under the name of Zwetotschny. Semi-erect growth, long, loose clusters, conical with up to threefold grapes without wings, round, small green/yellowlish berries with uncoloured fruit flesh. Very good resistance against winter and late autumn frost, good peronospora, oidium and botrytis tolerance, with little tendency to burst after autumn rainfall. Grapes have strong, musk aroma of flower blossom. High ability to gain sugar and through withering process well suited for sweet winemaking.


Merzling X Gim 6494 (Saperavi severnyi X St. Laurent); Merzling itself was bred from Seye Villard 5-276 X (Rieselung X Rulander) and Gm 6494 consists in turn f

rom Zarya Severa X St. Laurent. Since the year 1977 with variety protection, only Vitis Vinifera, from Freiburg im Breisgau / Germany. Sprouts late, on average sensitive to frost, small susceptibility to peronospora & oidium. Berries ripen medium to late. The wines are fresh and subtly fruity. In the case of good, physiological ripening of the grapes very harmonious, tender and similar to Bürgunder.


Solaris X Gelber Muskateller Solaris = Merzling X Zarya Severa x Muskat-Ottonel; only Vitis Vinifera since 1987 with variety protection from Freiburg im Breisgau / Germany. Very high resistance against peronospora – adequate resistance against oidium, strong growth, medium ripening time, inconsistent yield, high ability to produce sugar; intensive wines of Muskat type.

Souvignier Gris

Bronner X Cabernet Sauvignon; Bronner = Merzling X Saperavi X St. Laurent; combination of Vitis Vinifera Vitis Rupestris, Vitis Aestivalis and Vitis Amurensis types, since 1983 with variety protection, from Freibung im Breisgau / Germany. Very good resistance against peronospora & oidium, onion skin to red berry colour, generally later berry ripening, reduced cluster density and thicker berry skins mean grape decay is rare; strong as well as colour intensive wines which paired to Riesling with Burgund wines – with its powdery notes – also hint of Sauvignon.
