EXPLANATORY NOTES
INTRODUCTION
1 This publication presents final estimates from the ABS collections: Inventories of Australian Wine and Brandy, 2009-10, Wine and Spirit Production, 2008-09 (Annual Wine Survey), Sales of Australian Wine by Winemakers, 2009-10 and Vineyards, 2010. Not all data from these collections are published here. Some further data are available for a charge, on application to the ABS.
2 This publication is a summary of statistics on grape and wine production and related activities collected by the ABS and from other sources. Some of the data used in this publication were obtained from various ABS collections for which publications with appropriate Explanatory Notes are already available. The bibliography contains a list of these publications.
3 The Viticulture tables replace the previous publication Viticulture, Australia (cat. no. 7310.0) and contain information on area of vines and production of red and white grapes for the 2010 season. The continuing collection of varietal data is supported by Australia's grape-growers and winemakers and the Australian government through the Grape and Wine Research and Development Corporation.
4 Differences exist between the grape production intended for winemaking reported by grape growers in the viticulture collection and the quantity of fresh grapes crushed by winemakers reported in the Wine and Spirit Production Collection. Differences in the collection methodologies, as outlined below, mean some difference should always be apparent between the series.
SCOPE AND COVERAGE OF VITICULTURE SURVEY
5 Viticultural statistics relate to the year in which the harvest occur.
6 Prior to the 1999 collection, an exercise was undertaken to increase the number of known growers included in the collection. The improved coverage, of over 1,000 growers, means that the data presented for 1999 and later years are not directly comparable with data for previous years.
7 In contrast to previous years, 2009 Vineyards collection was undertaken using a survey methodology and collected information on the major wine grape varieties only. The scope of the 2009 Vineyards collection was agricultural businesses recorded on the ABS Business Register (ABSBR) above a minumum size cut-off. The ABSBR is based on the Australian Business Register (ABR) which is administered and maintained by the Australian Tax Office (ATO). This business based frame replaces the land based frame previously used for the Vineyards collection. The methodological changes mean that the data presented for 2009 are not directly comparable with previous years.
8 The 2010 Vineyards collection reverted to a census of all in-scope vineyards using the ABSBR as the frame.
9 Tasmanian data are collected in partnership with the Department of Primary Industries and Water. The scope of the collected data is the same as for other states.
SCOPE AND COVERAGE OF WINE SURVEYS
10 Winemakers who crush 50 tonnes or more of grapes are included in the Wine and Spirit Production collection. Wine production data are collected from these winemakers on a winery (location) basis to allow for state and regional data output. The grapes crushed by these wineries includes grapes owned by others and crushed on a commission or contract basis, often for wine producers who do not have their own crushing facilities.
11 Winemakers who crush more than 400 tonnes of grapes are included in the Inventories of Australian Wine and Brandy collection. These details on inventories of Australian beverage wine by wine type are collected at 30 June.
12 Winemakers with sales of 250,000 litres or more in either of the previous two years are included in the Sales of Australian Wine by Winemakers collection. All sales data are collected on an Australia-wide basis only and state figures are therefore not available.
13 Wine surveys are intended to identify and collect as much relevant activity as possible. The coverage limitations described in paragraphs 10 to 12 result in the exclusion of a small amount of activity relating to wineries believed to fall below the coverage limitations when surveyed. The total amount of activity excluded is believed to be between 2% and 5%.
14 All inventories data are collected on an Australia-wide basis only and state figures are therefore not available. Inventories data collected from 1996 include all Australian-produced wines owned by these winemakers and held anywhere in Australia. In years previous to 1996, inventories included only those Australian-produced wines held by winemakers on any of their own premises, regardless of ownership. This change in the measurement of inventories means that data for 1996 and later are not directly comparable with earlier years.
15 It is possible that inventories data may vary slightly each year as new wineries, with either large or small inventories, come into the scope of the collection. In particular, the published (i.e. closing) inventories figures for any one year may not equate with the opening inventories for the following year.
16 The wine content of products consisting of a mixture of wine and fruit juice, commonly known as ‘coolers’, is included in the appropriate wine category of the wine from which it is made, which is generally table wine.
