Alba Rossa is a red grape variety that was bred in 1938 by Giovanni Dalmasso at the Istituto Sperimentale per la Viticoltura in Conegliano in the Veneto region. It is a crossing of the varieties Nebbiolo and Barbera di Dronero. Almost at the same time came the grape Bric. Currently she is breeding processed by Franco Mannini. Since 2001, their cultivation in the Italian region Piedmont, Alessandria, Asti and Cuneo in the provinces is approved.
Synonyms: XV/31, Dalmasso 15-31, Incrocio Dalmasso XV -31.
Ethnicity: Nebbiolo x Barbera di Dronero. With the same crossing partners also developed the varieties Cornarea, Nebbiera, San Michele and Superga. The Barbera grapes as crossing partners retired after a DNA analysis of the father places.
Ampelographic varietal characteristics
In the ampelography the habit is described as follows:
- The shoot tip is open.
- The medium-sized leaves are five-lobed and indented slightly marked ( see also the article sheet form).
- The pyramidalförmige grape is shouldered, medium sized and quite dichtbeerig. The oval berries are small and of a bluish - violet color.
The grape ripens about 30 days after Chasselas and is thus regarded as late maturing. The grew strong variety delivers consistently high yields.
