Barossa power, with mathematical precision 🍷📐

The 2023 Standish The Schubert Theorem is one of Barossa’s most revered wines—now recognised as a Classified (Second Growth) in Langton’s Classification. Crafted from old-vine Shiraz from the Roennfeldt Road vineyard in Marananga, this is a wine of intensity, purity, and length.

The name? A nod to knot theory—specifically mathematician Horst Schubert’s idea that complex knots can be broken down into simpler, prime components. In much the same way, The Schubert Theorem is the sum of its perfectly selected parts: individual parcels that, when blended, create a wine of depth, tension, and detail.

Standish has become one of Australia’s most collectable modern icons—and this vintage proves why.

What the experts say about this wine

The 2023 The Schubert Theorem Shiraz is a gorgeous wine. It is silky, inky, pure, black as the ace of spades and long through the finish... It has rose petals, detail and delicacy, power and precision. Standish performs somewhat like a Burgundian producer—he works with one grape (I suppose two, if you count the small inclusion of Viognier in the Relic) to express different vineyard sites, soil types and elevations. There's no "declassified" fruit in these wines, no flow-on opportunities to other cuvées, just "make or break" viticulture and winemaking. The ancient terroir of the Barossa is writ large in these wines. It is striking. This 2023 Schubert, despite the cool and wet conditions, is a testament to Standish's clarity of vision.
