A GIS Analysis of New Zealand Terroir

Abstract

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

Oak wood barrel tannin potential builds white wines oxidative stability and contributes to wine metabolomics fingerprint

Considerable advances have been made in the chemical characterization of wine metabolites through its holistic study using both targeted and untargeted metabolomics approach. The metabolite pool is subject to an intense molecular dialogue which reinforces the wine complexity even after bottling.

Data fusion approaches for sensory and multimodal chemistry data applied to storage conditions

The need to combine multimodal data for complex samples is due to the different information captured in each of the techniques (modes).

Variety specific thresholds for plant-based indicators of vine nitrogen status

Aim: Several plant-based indicators of vine N status are reported in the literature. Among these, yeast assimilable nitrogen in grape must (YAN) and total N concentration of petiole and leaf blades are considered to be reliable indicators and so is the chlorophyll index, measured with a device called N-tester. The N-tester index is used to measure the intensity of the green colour of the leaf blade, and therefore to estimate its chlorophyll content.
