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.

Australian Journal of Grape and Wine Research

澳大利亚葡萄和葡萄酒研究杂志提供了一个交流有关葡萄栽培、酿酒学和相关领域新的和重要研究的信息的论坛，旨在在世界范围内推广这些学科。该杂志发表了葡萄栽培和酿酒学所有领域的原始研究结果。这包括与葡萄酒、餐桌和干葡萄生产有关的问题；葡萄和砧木生物学、遗传学、疾病和改良；葡萄栽培实践；果汁和葡萄酒生产技术；葡萄和葡萄酒微生物学；加工、包装和投入的质量影响；葡萄酒化学；感官科学和消费者偏好；葡萄和葡萄酒生产对环境的影响。也可以考虑与其他发酵或蒸馏饮料相关的研究。除了完整的研究论文和评论文章外，还可以发表简短的研究或技术论文，展示从完整研究中获得的新的和高度热门的信息（即非初步数据）。包括研讨会和会议记录的专题和补充问题将定期出现。

The Australian Journal of Grape and Wine Research serves as a vital platform for the exchange of significant research findings in the fields of viticulture and oenology, aiming to promote these disciplines globally. The journal publishes original research results across all areas of viticulture and oenology, including issues related to the production of wine, table grapes, and dried grapes; the biology, genetics, diseases, and improvement of grapevines and rootstocks; viticultural practices; juice and wine production technologies; microbiology of grapes and wine; the impact of processing, packaging, and inputs on quality; wine chemistry; sensory science and consumer preferences; and the environmental effects of grape and wine production. The journal also welcomes research related to other fermented or distilled beverages. In addition to full research articles and review papers, brief research or technical papers showcasing new and highly relevant information derived from complete studies (i.e., non-preliminary data) will also be considered for publication. Themed and supplementary issues, including proceedings from workshops and conferences, will be published regularly.
