Zierfandler is a rare Austrian white grape closely associated with the Thermenregion, south of Vienna. Best known around Gumpoldskirchen, it was already documented in the Vienna area in the eighteenth century. Roter Veltliner is one of its parents; the other remains unidentified but resembles Traminer. Despite the similarity in names, Zierfandler is not the same variety as Zinfandel. It produces wines with generous texture, well-defined acidity and considerable ageing potential.

In the vineyard

Zierfandler needs a favourable site to ripen reliably. In the Thermenregion, harvest usually takes place in mid- to late October, later than for Rotgipfler. As the grapes ripen, berries exposed to the sun develop a reddish blush. This explains its local name, Spätrot, meaning “late red”, although the grape is used to make white wine.

Sunny slopes and limestone-rich soils suit it well. Its bunches are densely packed, making the variety susceptible to botrytis. Wet autumn weather can complicate the harvest, while a warm, relatively dry season gives growers more time to reach full ripeness.

In the glass

Young Zierfandler often shows citrus and pineapple aromas. The wines can be substantial without feeling heavy, thanks to their balancing acidity. With bottle age, good examples develop notes of dried fruit, flowers, nuts and spice.

Both dry and sweet styles are made. Fuller dry wines suit roast poultry, fish and creamy dishes, while concentrated late-harvest wines can reward patient cellaring. Some sweet examples are also produced from botrytised grapes.

A local tradition

Zierfandler was traditionally blended with Rotgipfler, particularly in Gumpoldskirchen’s well-known Spätrot-Rotgipfler wines. Today, single-variety bottlings are increasingly common.

Small plantings also exist in Hungary, where the grape is known as Cirfandli. Despite its wider history, Zierfandler remains strongly tied to the Thermenregion, giving this corner of Austria a distinctive white wine tradition.
