The vines were planted in the garden of Arthur Phillip, then Governor of the colony, in a site that is now the location of a hotel on Macquarie Street in Sydney. Phillip's early vineyard did not fare well in the hot, humid climate of the region and he sent a request to the British government for assistance in establishing viticulture in the new colony.

  • 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.

  • Inquiry Into Wine Grape Market and Prices
    Submission No 14 INQUIRY INTO WINE GRAPE MARKET AND PRICES Organisation: Wine Grapes Marketing Board Date received: 21/09/2010 WINE GRAPES MARKETING BOARD SUBMISSION TO THE NSW LEGISLATIVE COUNCIL STANDING COMMITTEE ON STATE DEVELOPMENT INQUIRY INTO THE WINE GRAPE MARKET AND PRICES SEPTEMBER 2010 Introduction 1. The Wine Grapes Marketing Board (Board) currently operates under the NSW Agricultural Industry Services Act 1997, the Act and its regulations confers on the Board a specific range of services that it provides to all independent wine grape producers in the City of Griffith and the Local Government Areas of Leeton, Carrathool and Murrumbidgee. 2. The Board has been in operation in the region since 1933, originally setup to countervail the power of wineries in the region. The Board until 2000 had legislation in place through the then NSW Marketing of Primary Products Act to vest the regional wine grape crop and negotiate prices with wine grape purchasers. This ability was stripped from the Board following an extensive competition policy review from which the Board retained the countervailing power to set and enforce terms and conditions of payments for wine grapes that were not subject to a complying contract as prescribed in the current Act. 3. The Board is primarily funded by independent growers by placing a charge on all production at a rate of $3.90 per tonne. This amount is approved by growers each year in accordance with the provisions of the Act. 4. The Board operates in the wine geographical indication called Riverina which produces approximately 16% of Australia’s wine grapes and 65% of New South Wales wine grape production.

Wines are judged “blind” by panels which are usually made up of wine professionals – winemakers, journalists, sommeliers etc. The Australian Wine Industry Directory lists about 66 shows for the calendar year in which wines are awarded gold, silver and bronze medals. If the 20 point scale is used, a wine must score at least 18½ to earn gold, and on the 100 point scale a minimum of 95 is required. Of the extensive list of wine shows, Winewise chooses 20, from which only gold medal winners are invited to enter the Championship. That exclusive list is: Adelaide Hills Wine Show Australian Alternative Varieties Wine Show Barossa Wine Show Canberra Regional Wine Show Clare Valley Wine Show Geelong Wine Show Gippsland Wine Show Hunter Valley Wine Show International Riesling Challenge International Sweet White Challenge Langhorne Creek Wine Show Limestone Coast Wine Show Margaret River Wine Show McLaren Vale Wine Show Mornington Peninsula Vignerons Wine Show Mudgee Wine Show National Cool Climate Wine Show National Wine Show New England Wine Show (Incl.

  • Aglianico from Wikipedia, the Free Encyclopedia
    Aglianico From Wikipedia, the free encyclopedia Aglianico (pronounced [aʎˈʎaːniko], roughly "ahl-YAH-nee- koe") is a black grape grown in the Basilicata and Campania Aglianico regions of Italy. The vine originated in Greece and was Grape (Vitis) brought to the south of Italy by Greek settlers. The name may be a corruption of vitis hellenica, Latin for "Greek vine."[1] Another etymology posits a corruption of Apulianicum, the Latin name for the whole of southern Italy in the time of ancient Rome. During this period, it was the principal grape of the famous Falernian wine, the Roman equivalent of a first-growth wine today.

From Greece it was brought to Italy by settlers to Cumae near modern-day Pozzuoli, and from there spread to various points in the regions of Campania and Basilicata. While still grown in Italy, the original Greek plantings seem to have disappeared.[2] In ancient Rome, the grape was the principal component of the world's earliest first-growth wine, Falernian.[1] Ruins from the Greek Along with a white grape known as Greco (today grown as Greco di Tufo), the grape settlement of Cumae.

  • New South Wales' Wine Regions Showcased to the World
    Tuesday, 23 September 2014 New South Wales’ Wine Regions Showcased to the World New South Wales Wine Country, a new 128-page informative coffee table book which promotes the State’s wonderful and varied wine regions has been launched today. The guide produced by the Government’s tourism and major events agency, Destination NSW, in partnership with the NSW Wine Industry Association, gives an overview of the State’s 14 wine regions, including the wine terroir, local produce, food festivals and events, attractions, maps and information on how to get there. “I am delighted to launch the New South Wales Wine Country book which will encourage people from around Australia and the world to visit the many wonderful wine regions we have on offer in our great State,” Mr Stoner said. “The NSW wine industry is the oldest in Australia from the iconic Hunter Valley, Mudgee, Orange and the Riverina to lesser known gems such as the Shoalhaven Coast to the New England and the Hastings River, a smaller developing wine region with 150 hectares cultivated on the North Coast. “Annually NSW wine tourism contributes an estimated $1.6 billion into the economy and wine sales generates over $1 billion and accounts for more than a quarter of Australia’s production to key export markets, such as, the USA, UK, Canada, Germany, Japan, The Netherlands and New Zealand, with growth to Asian markets, including China and Singapore. “The production of this book proves the NSW Government is dedicated to supporting this important industry and has a focus on growing wine tourism, so I encourage you all to visit our cellar doors, dine in Regional NSW restaurants, shop at local farmers’ markets and ask for NSW wine next time you dine out or visit your local bottle shop,” he said.

  • Cultivar, Site Or Harvest Date: the Gordian Knot of Wine Terroir
    Metabolomics (2020) 16:52 https://doi.org/10.1007/s11306-020-01673-3 ORIGINAL ARTICLE Cultivar, site or harvest date: the gordian knot of wine terroir L. M. Schmidtke1 · G. Antalick1,2 · K. Šuklje1,3 · J. W. Blackman1 · J. Boccard4 · A. Deloire1,5 Received: 17 July 2019 / Accepted: 30 March 2020 © Springer Science+Business Media, LLC, part of Springer Nature 2020 Abstract Introduction The complex interactions of vine cultivars, and localised regional climate associated with specifc vineyard sites are important attributes to the concept of terroir and signifcant contributors to grape maturity and wine sensory profles. An improved understanding of the infuence of each factor and their interactions is a challenging conundrum, and will enable more efcient production targeting specifc wine styles. Objectives To characterise the metabolic fux of grape berries and resulting wines to characterise the relative impact of site specifc climate, cultivar, and grape maturity based upon berry sugar accumulation models that consistently target specifc wine styles. Methods A spatial and temporal study of grape and wine composition was undertaken for two important cultivars in two distinct regions of New South Wales. Measures of composition and wine sensory ratings were simultaneously analysed using a multiblock algorithm taking advantage of the ANOVA framework to identify important contributions to wine style arising from grape maturity, vineyard site and cultivar. Results A consistent fux of grape and wine constituents is evident for wine made from sequentially harvested grapes from the same vineyard with increasing levels of grape maturity. Contributions of region and vineyard site to wine style could also be elucidated.
