Langmeil sits in the Barossa Valley on a site where German settlers first planted vines in 1842, and the winery was re-established by the Lindner family in 1996. Massimo is an unusual Italian-variety blend of Montepulciano and Primitivo grown in the Barossa's warm, dry continental climate, a departure from the district's Shiraz and Grenache heritage. The vineyards lie on the valley floor's sandy to clay-loam soils, farmed for balanced ripening in the region's reliably warm summers. The warm 2023 Barossa growing season suited these heat-loving southern-Italian varieties, allowing full flavour development and firm colour while retaining the savoury, spice-driven profile the blend is built around.

The fruit was fermented in open fermenters with gentle hand-plunging to draw colour and tannin softly from the skins, in keeping with Langmeil's traditional, low-intervention reds. After pressing, the wine was matured for around twelve months in seasoned French and American oak, the older barrels chosen to add structure and integration without imposing overt oak flavour on the fruit. This élevage preserves the dark-cherry fruit and savoury, spice-led character of the Montepulciano-Primitivo blend while giving supple tannins and a rounded finish suited to earlier drinking.
