Lagrein

 

Synonym: Lagrain.

 

Commonly mistaken for: Lagarino.

                                                                    

Origin: The origins of this variety are uncertain although its name comes from the word “Lagara”: a Greek colony, famous for its wine: Lagaritanos. Marzotto (1925) has affirmed that the name "Lagrein" derives from Val Lagarina (zone of the Trentino region), but since the 16th century this variety was cultivated in the lowlands of Gries of the Bolzano province in the Alto Adige region, by Benedictine monks. This variety is not very homogeneous; in fact some authors have confirmed the existence of two fundamental typologies: the Lagrein with short bunch and the Lagrein with long bunch. These two biotypes are different not only for dimension and form of the bunches, but also for qualitative characteristics of the final product. To the first biotype corresponds the wine Kretzer, a rosè wine, very low in colour; while to the second biotype corresponds the wine Dunkel and Bauernlagrein, of intense and dark colour. 

 

Agronomic and environmental aspects: This vine is very adaptable to different climates, having an late time of budburst it can be escape to spring frosts. It has a preference for soils with a good percentage of sand, with medium-low fertility. In Italy traditional wide training systems are used, such as pergola with long pruning, also to reduce the vigour of the vines, weak rootstocks are used (101.14, Schwarzmann and 5C Teleki). Variety that shows a good and  quite constant yield. Good results can also be obtained with spurs pruning and VSP, but a thinning of bunches is advisable to avoid possible attacks of botrytis and improve the quality of the wine.

 

Diseases, pests and disorders: Susceptible to attacks of mites, it shows a good resistance to downy mildew, powdery mildew and sour bunch rot. Particularly sensitive during flowering, because of the low quantity of pollen in the flowers, so frosts and rains can cause alternation of production and “hen and chicken”.
