Abstract
While winegrowers usually want to achieve consistent yield targets, there is a high degree of yield and price (and hence gross revenue) variability in winegrape production. The aim of this study was to determine whether there are differences in yield and revenue variability across climates, varieties, and regions in Australia. This was performed by estimating statistical models of the impact of these three variables on the coefficient of variation of yield and gross revenue per hectare. The results suggest that hotter and drier regions exhibit lower interannual yield variability, something that in the past may have been largely explained by the use of irrigation, but which may change in the future with climate change and higher water prices. The results also showed that there are sometimes differences in yield and revenue variability, not only across regions, but also between varieties.
期刊介绍：
The Australian Journal of Grape and Wine Research provides a forum for the exchange of information about new and significant research in viticulture, oenology and related fields, and aims to promote these disciplines throughout the world. The Journal publishes results from original research in all areas of viticulture and oenology. This includes issues relating to wine, table and drying grape production; grapevine and rootstock biology, genetics, diseases and improvement; viticultural practices; juice and wine production technologies; vine and wine microbiology; quality effects of processing, packaging and inputs; wine chemistry; sensory science and consumer preferences; and environmental impacts of grape and wine production. Research related to other fermented or distilled beverages may also be considered. In addition to full-length research papers and review articles, short research or technical papers presenting new and highly topical information derived from a complete study (i.e. not preliminary data) may also be published. Special features and supplementary issues comprising the proceedings of workshops and conferences will appear periodically.
