Mary Kathleen is named after family matriarch, Mary Kathleen Lloyd, one of the founders of Coriole. It is produced from three small, select vineyards on Coriole's estate. The wine was first produced in 1992.
A 95/5% blend, the cabernet planted in '66, the components separately open-fermented and blended after mlf, in all 20 months before bottling, then 2 years in bottle before release. Conceived as elegant and concentrated compared to normal opulence of McLaren Vale, I'll split the difference and agree that the hallmark of the wine is concentration, indeed extreme concentration.
