  • NSW Food & Wine Tourism Strategy & Action Plan 2018
    New South Wales Food & Wine Tourism Strategy & Action Plan 2018 - 2022 FOREWORD The NSW Food & Wine Tourism Strategy & Action Plan 2018 - 2022 is designed to provide the food and wine sector and the tourism industry with an overview of Destination NSW’s plans to further support the development of food and wine tourism to the State. NSW attracts more domestic and international visitors than any Australian State, giving us a position of strength to leverage in growing consumer interest and participation in food and wine tourism experiences. The lifeblood of this vibrant industry sector is the passion and innovation of our producers, vignerons, chefs and restaurateurs and the influence of our multicultural population on ingredients, cooking styles and cuisine and beverage purveyors. NSW is also home to the oldest and newest wine regions in Australia, world renowned for vintages of exceptional quality. From fifth-generation, family-owned wineries to a new generation of winemakers experimenting with alternative techniques and varietals, the State’s wine industry is a key player in the tourism industry. Alongside our winemakers, a new breed of beverage makers – the brewers of craft beer and ciders and distillers of gin and other spirits – is enriching the visitor experience. The aim of this Strategy & Action Plan is to ensure NSW’s exceptional food and wine experiences become a highlight for visitors to the State. Destination NSW is grateful to the many industry stakeholders who have contributed to the development of this Strategy and Action Plan, and we look forward to working together to deliver outstanding food and wine experiences to every visitor.

  • Spatial Analysis of Climate in Winegrape Growing Regions in Australia
    Hall and Jones Climate in winegrape growing regions in Australia 389 Spatial analysis of climate in winegrape-growing regions in Australia_100 389..404 A. HALL1,2 and G.V. JONES3 1 National Wine and Grape Industry Centre, Charles Sturt University,Wagga Wagga, NSW 2678, Australia 2 School of Environmental Sciences, Charles Sturt University, PO Box 789, Albury, NSW 2640, Australia 3 Department of Environmental Studies, Southern Oregon University,Ashland, OR 97520, USA Corresponding author: Dr Andrew Hall, fax +61 2 6051 9897, email [email protected] Abstract Background and Aims: Temperature-based indices are commonly used to indicate long-term suitabil- ity of climate for commercially viable winegrape production of different grapevine cultivars, but their calculation has been inconsistent and often inconsiderate of within-region spatial variability. This paper (i) investigates and quantifies differences between four such indices; and (ii) quantifies the within-region spatial variability for each Australian wine region. Methods and Results: Four commonly used indices describing winegrape growing suitability were calculated for each Australian geographic indication (GI) using temperature data from 1971 to 2000. Within-region spatial variability was determined for each index using a geographic information system. The sets of indices were compared with each other using first- and second-order polynomial regression. Heat-sum temperature indices were strongly related to the simple measure of mean growing season temperature, but variation resulted in some differences between indices. Conclusion: Temperature regime differences between the same region pairs varied depending upon which index was employed. Spatial variability of the climate indices within some regions led to significant overlap with other regions; knowledge of the climate distribution provides a better understanding of the range of cultivar suitability within each region.

Tonnes purchased may be slightly higher than the sum of tonnes in all price ranges as some fruit does not have a price specified. 2. Where there are fewer than three purchasers of a variety, the average price and total value are not reported. 3. The estimated non-response rate nationally is 9.5%; however, the non-response rate varies for each region. Generally, regions with more small wineries and less purchased fruit will have higher non-response rates. As the number and identity of respondents can change from year to year, changes in the size of the crush can be partly attributable to changes in the non-response rate.

The varied nature of the climate and terroir mean that countless varieties are planted, creating regional heroes that are unique and expressive. From the delicate chardonnays with natural acidity from Tumbarumba in the Snowy Mountains, to spicy shiraz of the Canberra district, to medium bodied Hunter shiraz and world- famous semillon, NSW is an enviable State to be in. Canberra District Established in the 1970s, the Canberra region comprises three sub regions with more than 30 wineries and 350 hectares of vines. The area produces stunning riesling with high acidity and elegant spicy shiraz wines. Climate: continental Best varieties: shiraz and riesling Must-see cellar doors: Lark Hill Winery, Clonakilla, Eden Road Wines, Helm Wines, Capital Wines Dining: Grazing at Gundaroo, The Poacher’s Pantry Key experience: The Poacher’s Way food and wine trail Events: The annual International Riesling Challenge in Canberra; Canberra District Wine Harvest Festival.

  • 1 Assessing the Use of Geographical Indications for the New England Wine Region in NSW
    Assessing the Use of Geographical Indications for the New England Wine Region in NSW Hui-Shung (Christie) Chang, Gene Campbell and Peter Sniekers* Paper presented to 51st AARES Annual Conference 2007, Queenstown, New Zealand, 13-16 February 2007 Abstract Geographical Indications (GIs) have increasingly been used as a marketing tool to create an image of quality and uniqueness, and so capture premium prices. Hedonic pricing studies have shown that indication of geographical origin of production (e.g. country, region, wineries, and location), can affect prices. However, Geographical Indications only work when they are backed up by quality products. The objectives of this study are to assess the potential of a proposed Geographical Indication for the emerging “New England” wine region in promoting local wines and to make recommendations on how that potential, if it exists, can be realised. The assessment is based on an overview of existing systems of Geographical Indications and conditions, both economic and regulatory, which are required for successful geographical indication applications. Key words : geographical indication, TRIPS Agreement, wine marketing, hedonic pricing. *Christie Chang and Gene Campbell are Senior Lecturer and honours student, respectively, in the School of Economics, University of New England and Peter Sniekers is Agribusiness Development Manager, New England – North West, with the NSW Department of State and Regional Development.
