Thermenregion starts on the edge of the Wienerwald forest just 5km south of Vienna. It’s a region of two distinct parts, the result of a merger in 1985. Nearest to Vienna, two niche white grape varieties prevail – rotgipfler and zierfandler.
See later post for the reds of pinot noir and saint laurent, which grow further south.
Rotgipfler and zierfandler have both been around for a long time, and, said Bernhard Stadlmann, of Weingut Stadlmann they “are the two most noble grape varieties of Austria, along with riesling and grüner veltliner.” Neither are widely planted – “there are around 140 hectares of rotgipfler and 120 ha of zierfandler” said Willi Balanjuk of Freigut Thallern, one of the oldest wineries in Austria, founded by Cistercian monks in 1141.
In the north, vineyards lie on an east-south-east facing limestone slope around 200 to 400m above sea level. Balanjuk said this “slightly hillside location, at the east of the Alps, produces concentrated medium bodied wines based on limestone.” The vineyards around Gumpoldskirchen were historically regarded as the most favoured for growing rotgipfler and zierfandler, and these were traditionally blended together, but now are increasing made as single varietal wines.
Both varieties are based on the traminer family so inherent perfume is one of their trademarks, though rotgipfler “has a more constant aromatic profile” said Balanjuk. And where rotgipfler has thicker skins and takes on a green gold hue with ripeness, so zierfandler has thinner skin and takes on a red hue with ripeness, hence is alternative name spätrot.
Rotgipfler’s thicker skins give it some protection against botrytis. Balanjuk said it characteristically has “the honey, yellow melon nose of viognier, plus ripe pear characters of chenin blanc, with a good concentration and texture.” And, he added the aromas develop best in the second year, needing the first year to develop intensity and complexity. Stadlmann added “we see more riper fruit, lush pear, tropical mango, warmer fruit, and warm spice.”
Rotgipfler’s acidity is fresh but not high, whilst zierfandler “has more acidity than rotgipfler, with a similar structure to riesling” said Stadlmann, and it expresses “colder fruit – lime, lemon, fresh melon, quince, fresh apple, citrus.” These are accentuated in youth, he added, with “fresh green apple, pear, floral notes and some smokiness.” Balanjuk added zierfandler “is a very textured wine, and can be slightly honeyed with the rose leaves of traminer.”
With its thin skin and good acidity levels, zierfandler lends itself to sweet wines. Stadlmann said “we’re not far from Burgenland but the temperature is very different. There are warm nights in Burgenland, but in Thermenregion we always have cool breezes through the vineyards at night, from the mountains.” Sweet zierfandler is not necessarily botrytised, as Stadlmann explained “the fruit can be concentrated on the vine by evaporation through the skin, so you can go to beerenauslese with little botrytis”, adding “some winemakers use 3 or 5% botrytis.”
Mostly, wines are fermented in stainless steel or big old wood, and aged on lees in big wood. This is a good way to harness the aromatic potential without stifling the grapes natural expressiveness and structure. Though hugely niche, these are some tasty whites.
Whilst little rotgipfler or zierfandler is found outside Thermenregion, these two varieties account for around 10% of the region’s total vineyard, keeping their position very specific.
