These varieties, already analized through DNA at S. Michele all’Aldige, are included in a research project of ALSIA (Lucanian Agency for agriculture development) and the CNR located in Agriculture Department of the Università degli Studi della Basilicata, in coordination with Bari’s experimental institute, Turi’s section.
This project is aimed to the recover and the possible development of Vulture’s historic and wine heritage.
The rootstocks used on the new implants are in prevalence the 420A, a small part is on 140R and another small part on SO4 and Rupestris Du Lot.
In surround the vineyard, there are about one hundred of olive trees of mean age over 40 years, of Ogliarola del Vulture’s variety.
Piano dell’Altare vineyard is situated in Ginestra’s municipality, in the district of the same name, and it is made up of one plot of 5.78.86 ha on the whole.
It has a mean altitude of 440 mamsl, with a slope of about 12% and row orientation East-West.
Going in the main natural path, it is well visible the land stratigraphy characterized by volcanic tuff (at a variable depth from 50 until 150 cm) and arable soil of mean dough which is nearly clay.
The presence of volcanic tuff is warranty of “water capacity” for the vineyards, seeing as it can be carried out a summer water stock function. The climate, indeed, is characterized by a rainfalls of about 700 mm, concentrated in November- June span, and by a lengthened dry season in summer period.
The spacing of the vines is of 2,20 x 0,90 m that produces a mean of about 5000 plants/ha. The implant year is 2003 for about 65%, 2004 for about 11% and 2006 for about 13%. The remaining part (about 11%) is made up of historic vineyards, going back, as implant, to the first years of the last century.
A portion of these vines (those resulting from the transformation of the old spacing 1,00 x 1,00 in 2,00 x 1,00 m – from “alberello” to espalier), for the genetic importance they represented, after health and genetic evaluation carried out in collaboration with the Agriculture Department of the Università “Federico II” of Naples and the “S. Michele all’Aldige” institute, has been transplanted in acreages of the same plot.
A good part of these old vines, result propagating for offshoot (an underground shoot give raise to a new plant) and, hence, are considered ungrafted without phylloxera symptomatology. From here an absolute wine importance.
The varieties are constituted from a 72% of Aglianico del Vulture, an about 11% of Fiano, about 10,5 % of Moscato and Malvasia. The balance (about 1,5%) is made up of about forty different varieties, found in loco on the basis of indications go back to files of 1800 found in Portici's Agriculture Department Library.
