St Hallett Old Block Shiraz, first vintage 1980, is a stalwart of the Barossa and a stalwart of Langton's Classification of Australian Wine. A blend of oldvine Shiraz (average age 90 years) from key sites in the Barossa and Eden Valleys, Old Block is one of Barossas finest.

'One of Australia's highest quality single vineyard wines. The core has liqueur cassis qualities that are supported by fine velvet tannins that run with terrific length and tenacity. A wine for the discerning hedonist.' - Andrew Woodforth, Vintage Cellars Spit Junction. 'Now listed in the "exceptional" category of the Langton's Classification VI, this landmark red of the region hits you with wow-moment fruit, vibrant to the max and an OTT intensity rating. French oak adds a clove-like spice while the juicy core centres around super-concentrated raspberry rich flavours, the finish seems to last forever. Its history is profound and its cellar potential huge.' 5 Stars - Adelaide Advertiser, 14 May 2014, by Tony Love.

A single-block Shiraz from 80-year-old vines. Hand harvested. The fruit, spends 10 days on skins, hard pressings removed. Moved to puncheons for malolactic conversion & maturation, 14 months on oak. An approachable, yet complex, drop. A nose of Red berries, earthy tones & baking spice. A full & fleshy palate of plums, berries, dried spice, & chocolate with robust tannin structure.

The initials RWT stand for Red Winemaking Trial, the name given to the project internally by Penfolds when developmental work began in 1995. No longer a trial, RWT Shiraz was launched in 2000. Its style is opulent and fleshy, 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.Peak drinking: 2022 - 2050
