Before you rush out to spend $900 on the latest Penfolds Grange have a look at this

The 2014 Grange is about to hit the market with the first reviews out this morning. Tony Love in The Advertiser gives it 98 points out of 100 as a "solid gold Grange in body as well as soul, yet chamfered and measured, even subtly minerally but with no hard edges." For Frank Wilden at Business Insider it's a "great Grange" with the palate "ridiculously seductive and easy to enjoy with such generosity of character and balance."
And all that for the recommended retail price set by Penfolds at $900 a bottle - up $50 from last year's suggestion.
Before rushing out with your plastic have a think about this interesting summary of the prices collected and averaged from the four leading wine auction houses in Australia on a monthly basis by the wine auctioneers Wickmans.
