Meshach William Burge was Grant's great grandfather and was a central figure in establishing the Burge family in the Barossa Valley. This Shiraz named in his honour is sourced from old vines, some nearing 100 years old, and shows aromas and flavours of complex swiss chocolate, savoury spices and red currant. Grant Burge's flagship shiraz will reward the patient cellarer with 20 years in the bottle in front of it.

The initials RWT stand for Red Winemaking Trial, the name given to the project internally when developmental work began in 1995. RWT is made from fruit primarily selected for its aromatic qualities and plush texture. The result is a wine that helps to redefine Barossa shiraz at the highest quality level. Built for the long haul, with the precision, concentration and balance to age for many years. Onyx, ruby rimmed colour. Floral and berry notes on the nose, with a palate of dark cherry and blackcurrant fruits affording viscosity and concentration. Peak drinking: 2025 - 2050.

Rockford Basket Press Shiraz has garnered a unique and cult following over its lifetime. With its 'old school' brown glass bottle and traditional label, Rockford Basket Press is one for the traditionalists. Big, bold and upfront fruit with all the lashings of chocolate, coffee bean and Christmas cake all have come to adore.

Penfolds RWT Shiraz is a big juicy Barossan Shiraz refined by the use of older French oak barrels. 1998 is considered to be one of the classic vintages of the modern age. Drinking wonderfully now but with many years still to come in its development, this is a great addition to any cellar.

One of the benchmarks of Barossa Shiraz, Peter Lehmann's Stonewell is a classic example of the rich concentrated old vine style. While bold on the palate, there is always an inherent complexity to the Stonewell that enables it to be compared with all of the great Australian wines produced today.

The 2015 Steading has a fragrancy, purity of fruit, mid-palate concentration and savoury tannin profile that makes it an exemplary wine. Vibrant aromas of violet, star anise hints of violet and spice all unfold to reveal an impressive array of underlying fruit flavours. Silky, succulent dark fruits, black olive, savoury earth, liquorice and Asian spice. These complex yet elegant flavours are all neatly interwoven with a perfect balance of acidity and supple, silky tannins. The 2015 Steading will continue to develop with time in the cellar, and provide those with patience great enjoyment well into the next decade.
