Dear Mr Singh - I hope you have achieved success since you posted your message! If you (or any other reader) wish to continue to improve your knowledge of Australian and indeed international wines generally, please note that the wine site www.winepros.com.au has just opened as an archive, for free (previously was by payment only).
Winepros.com.au contains over 100,000 pages of articles, on wine regions in over 60 countries around the world, approx. 25,000 wine reviews and tasting notes from 1991-2005 (good for studying older vintages) and lots more, by reputable authors such as Clive Coates MW (a specialist in French wines, particularly of Burgundy), Robert Joseph, Bob Campbell MW, the late Len Evans (very few of his tasting notes are available elsewhere), and many others. It is a very valuable resource and anyone who wishes to learn more about wine will find much of interest there. And best of all, there is now no charge.
Yours - Pinotphile
