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.

The Langi Shiraz block at Mount Langi Ghiran is planted with Swiss clone material originally sourced from nearby Bests Concongella Vineyard. Postmodern vinification includes open fermentation with some whole bunch and regular hand plunging, followed by partial barrel fermentation. Maturation takes place for around 14 months in new (45%) and seasoned French oak. The expressive Langi Shiraz is typified by ethereal blackberry, brambly dark cherry and pepper aromas, supple textures and underlying savoury oak.

St Hallett Mighty Ox Shiraz (Magnum) St Halletts Mighty Ox Shiraz is a new icon for the heritage Barossa label. It is a decadent, classic style of Barossa Shiraz, saturated with black fruit and fit for many decades of cellaring.Fruit for this wine is sourced from several sites in the Northern Barossa, in Ebenezer, Greenock, and Moppa Hills. Bold and strong, it is named for the oxen that were once used to plough the soils of the Barossa. All parcels for this wine are treated individually, then spend 8 to 12 days of warm fermentation on skins. It is aged in American oak. The result is a full bodied showstopper, luscious and driving on the palate. The fruit intensity here is immense, with oak nuances teeming with vanilla and dark chocolate. The finish is incredibly long.

Their Reserve Shiraz is so highly thought of, it sits in the Outstanding category in Langton's Classification of Australian Wine. With fruit sourced from the '20 Rows' block in Langhorne Creek owned by the Borrett family, this is a Shiraz of serious weight and body. Still very young, aromas of violets, lavender and herbs are balanced with traditional fruit notes of blueberries and spice. Big and fleshy on the palate while still showing supreme complexity, this is a wine that needs some decanting before enjoying the saturating flavours that Noon can offer.
