A GIS Analysis of New Zealand Terroir


This paper summarises a national survey of the geological setting of vineyards in New Zealand. We also provide an overview of climate, slope, aspect and varietals planted in New Zealand vineyards as a whole and for some individual regions.
New Zealand produces premium quality wines and its wine industry is growing rapidly. Growing degree days in the winegrowing regions range from 900 in cool Central Otago and Canterbury to over 1600 in the warmest region in the country, Auckland. Average growing season temperatures for the same regions range from approximately 14.3°C to 17.6°C. New Zealand vineyards are planted mainly on flat alluvial and glacial gravels with slopes of less than 3°. Rapid growth is pushing new plantings onto adjacent hillsides that are underlained by greywacke, schist and less commonly limestone. The expansion of the industry onto these different substrates will affect grape and wine characteristics; this provides significant opportunities to develop new styles of New Zealand ultra-premium wines

High-altitude vineyards under extreme conditions in the PIWI context of cultivation: economic and marketing evidence from an exploratory study in Northern Italy

Viticulture has spread to unexpected locations, such as high-altitude terrain. Among these, high-altitude viticulture has captured considerable attention, not only for the uniqueness of its products and landscapes but also because it offers an effective response to climate changes
The aim of this study is to analyse and compare wineries that used Piwi varieties (acronym for the German Pilzwiderstandfähig, i.e., cryptogame-resistant) at high altitudes (between 500 and 920 m a.s.l.) with the traditional non-mountainous viticulture model.

Investigation on harvesting period choices for correct interpretation of experimental results

Happens too often in scientific papers to find the same harvesting period of a cultivar, although the used treatment influence a maturity curve of investigated thesis.
This inevitably leads to wrong conclusions when comparing the treatment effects, since obtained on maturity stages more or less far from those technologically correct.

Juice carbon isotope discrimination is related to vine growth and fruit quality of Barossa Shiraz

Aim: Interactions between soil, climate and management that modulate vine growth, yield and grape composition are strongly defined by vine water availability and nutrient uptake during the season. Carbon isotope discrimination (δ13C) has been used as an integrative measurement of vine water availability during the season, with the potential to identify spatial variations of terroir in

Recent advances in our understanding of the impact of climate change on wine grape production

According to the last IPCC report, the scale of recent climate changes are unprecedented over many centuries. Each of the last four decades has been successively warmer than any decade since 1850. Projections for the future foresee that temperature could reach +3.3°C to +5.7°C under the most pessimistic scenario. It is also projected that every region will face more concurrent and multiple changes in climatic impact-drivers. The frequency of extreme climate events is also likely to increase, as well as the occurrence of indirect constraints. These evolving climatic conditions are alrealdy affecting and will continue to affect the suitability of traditional wine grape production areas, but also create opportunities in new locations.
