Changing New Zealand climate equals a changing New Zealand terroir?

The technique of crossing, whether free or controlled, has always been a source of variability allowing the selection of new varieties with improved fitness.

In the current scenario of climatic variability, even though the vine (Vitis vinifera) is a species generally considered very fertile, the process of bud differentiation is particularly influenced by the weather trend not only of the current year but also of the previous one.

The interactive effects of three major enological variables were evaluated on the quality of Schiava wine up to one year of storage in bottle.

Aim: The aim of this work is educating people about soil variability, vine rootzone depth and readily available water holding capacity. The concept of terroir is readily discussed in the wine industry but many people involved are unable to describe a soil profile and interpret its limitations that impact on vine growth, fruit quality and wine produced. This paper discusses soil physical characteristics important to vine root growth and readily available water holding capacity (RAW).

The cultivar with a greater oenological potential was ‘Monastel’, which showed overall better values than ‘Tempranillo’ in colour intensity, total polyphenol index, wine colour, total anthocyanins, resveratrol and gallic acid.
