Rotgipfler

Rotgipfler is a white grape strongly associated with Austria’s Thermenregion, especially Gumpoldskirchen. Official cultivar records identify it as a natural cross of Traminer and Roter Veltliner. It is made as a varietal wine and traditionally blended with Zierfandler in Spätrot-Rotgipfler; regional sources describe ripe, extract-rich wines with apple, pear and fruit-spice character.

Zierfandler

Zierfandler is a rare Austrian white grape closely tied to the Thermenregion. Its synonym Spätrot refers to the blush that develops on sun-exposed bunches, even though the grape makes white wine. Austrian sources describe aromatic, extract-rich wines with citrus and tropical-fruit notes, often with some residual sugar. Its reported parentage includes Roter Veltliner and an unidentified Traminer-like vine.

Zweigelt

Zweigelt is Austria’s leading red grape, bred at Klosterneuburg in 1922 from St. Laurent and Blaufränkisch. Its style can be easy and cherry-fruited for early drinking or fuller and more age-worthy when yields are restrained. Austrian official sources describe dark sour-cherry and berry aromas, while also noting that crop management is important to quality.

Négrette

Négrette is the signature black grape of Fronton, north of Toulouse, and one of Southwest France’s most distinctive local varieties. Its aromatic identity can be floral and spicy, while its structure is not uniformly heavy: Plantgrape describes generally modest tannin and acidity, whereas Fronton producers make both lighter, fresh wines and more powerful examples intended to age. The grape’s precise historical origin is less certain than its modern home. Plantgrape gives Southwest France; the Fronton authority treats a local Tarn-area origin as more plausible than the old Cyprus legend.

Barbera

Barbera is a black grape whose high natural acidity is one of its most useful identifying features. Its Piedmont home includes several distinct wine identities—from fresh, fruit-led reds to oak-aged Superiore and the more tightly defined Nizza DOCG. Italian Vitis Database confirms the cultivar using morphology and SSR markers and notes that Barbera has few important synonyms, despite several unrelated local grapes that borrow the name. The name on a bottle therefore needs careful reading: Barbera d’Asti and Nizza describe protected wine origins, not additional cultivars.

Dolcetto

Dolcetto is a black grape strongly associated with southern Piedmont. Dolcetto d’Alba is described by its consortium as dry, fresh and fruity, with a violet-ruby colour and bitter-almond aftertaste. The name should not be read as a promise of sweet wine. Italian Vitis Database lists Ormeasco as an official synonym scoped to western Liguria, while warning against several misleading historical names.
