Environmental studies: influence of soil and altitude on vine qualities “ Teran” and “Istrian Malvasia”

The aim of this research is to individuate the influence of soil (terra rossa and flysch) and of altitude (low localities and high localities) on the quality of two autochtone vine varieties in Istria: “Istrian Malvasia” and “Teran”. On this purpose vineyards in full maturity were selected in Poreč and Motovun on terra rossa and flysch. During the maturation of must values of sugar and pH have been followed. After the vinification chemical and organoleptical analysis were performed and on this basis a determination of economic quality (QE) of vines was performed too. On the basis of enochemical, organoleptical and economic results emerged a net influence of soil type and altitude.
