The 2021 The Schubert Theorem Shiraz was made with fruit from the Roennenfeldt Road vineyard, in Marananga, with 70% whole bunches in the ferment. The northeastern corner of this vineyard is matured in concrete egg to preserve the blue-fruited core that defines the style of this wine; it is the only cuvée that features an alternate maturation vessel. I knew (before and) when I tasted the 2019 and 2020 vintages what I was going to get, by and large. When I was in the Barossa in June 2021, I was already thinking about what the Schubert would look like from this year, as the perceived fit of season and style had the potential to dovetail in a most titillating fashion—a "stars aligning" kind of thing. A cool season overlays a warm site capable of producing dark, dense, sometimes brooding, always pure Shiraz. The combination of concrete egg (and, in this case, a slightly shorter maturation in this vessel) and cooler year has produced a wine of scintillating precision and fruit sweetness. It glows with its own black light. It shimmers and oscillates between fruit luminescence and plush tannic texture, and in doing so, it barely contains its own energy and abundance. The distinction between this profusion of fruit and the old "fruit bombs" of yore is the precision of acid and pliable fruit tannin that defines the middle palate and the ability of the fruit (courtesy of the winemaking) to shine through the vessels in which it matured. The tannin that shapes the wine is plentiful, make no mistake, yet it is ductile and fine and threads through every aspect of the palate. A thrilling Schubert this year, it's like a strike of lightning on a dark night. This wine appeals most fervently to my penchant for freshness, energy and resonant bass line. 14.9% alcohol.

The 2020 The Schubert Theorem Shiraz was made with fruit from the Roennfeldt Road vineyard in Marananga, with 70% whole bunches in the ferment. This is the only cuvée in the collection that sees any inclusion of a different maturation vessel: the northeastern corner of the vineyard goes into concrete, because it retains the pure blue fruit characters that so define the wine. When one considers the dirt that is in this vineyard (and I ask you, without dirt, just where would we all be?), when one sees its black, shaley sparkle, one can get a sense of what to expect in the wine. It is always the black, brooding beast of the pack, but there is always—and I repeat, ALWAYS—a core of very pure fruit at its heart. This year is no different, and it is encased in fine but structuring tannin. It soars long across the palate, and yet within it, this wine is elegant and pliable. If the Lamella is the intriguing, pretty wine, and The Standish is the savory powerhouse, then The Relic is the iron fist–velvet glove... which makes this the enigma. I cannot overstate how attracted I am to the prowling, slinking nature of it. The tannins here—of all the wines—have a blueberry skin gravel to them; they are chalky and fine and a little bit gritty… excellent. This is a sensation, in every respect. A hot contender for best wine in the release this year.

Mint, sage and thyme accent blackberry and black cherry fruit in the 2018 The Schubert Theorem Shiraz. Full-bodied and rich without being heavy, it finishes tremendously long, with silky, cocoa-powder-like tannins. It should drink well for a couple of decades.

Mulberries and blueberries appear alongside a hint of white pepper on the nose of Standish's 2017 The Schubert Theorem Shiraz, sourced from Marananga. It's full-bodied, firm and structured, loaded with mixed berries and balanced by savory undercurrents of espresso and black olive. It finishes long and mouthwatering yet also dusty and tannic. Give it another 2-3 years in the cellar and drink it over the following decade or so.

From a Marananga vineyard, Standish's 2016 The Schubert Theorem Shiraz is even darker hued than The Relic. Blueberries, licorice and violets appear on the nose, while the full-bodied palate is rich and creamy-textured, growing more tannic and savory on the nearly endless finish. Monolithic and young, give this at least a couple of years to become more approachable.
