Mount Mary Quintet

When Dr John Middleton planted Cabernet Sauvignon, Merlot, Cabernet Franc, Malbec, and Petit Verdot on a single Yarra Valley estate in 1971, the Australian industry was still dominated by fortified wine — making the inaugural 1976 Quintet not just a debut but a provocation. That founding conviction has never wavered under three generations of Middleton family ownership. The estate sits on a gentle north-facing slope at Coldstream, where grey-brown sandy loam over rocky clay delivers sharp drainage and forces vine roots deep, concentrating mineral tension rather than fruit weight. Sea breezes channelled from Port Phillip Bay and Bass Strait moderate ripening across the long cool season, preserving the low-alcohol, high-acid architecture that defines the house. Quintet spends 22 months in a mixed oak regime: 30% new 225L barriques, 25% large-format foudres of 1,500L or larger, and the remainder in two-to-five-year-old barriques — the foudre fraction deliberately diluting new-oak imprint to keep fruit and site legible. Maceration runs 12–14 days on skins, building structure without extraction excess, and the wine is bottled with minimal fining and filtration. What no peer in the Southern Hemisphere replicates is the simultaneous pursuit of both Bordeaux and Burgundy idioms at this level from a single cool-climate estate. The 2016 vintage in the Yarra Valley delivered a cool, even growing season with excellent natural acidity; the Quintet from this year is tightly wound and cellar-dependent, with a drinking window extending comfortably into the mid-2030s.
