Mountadam vineyard was planted to a rocky escarpment at the highest, most elevated, southeast edge of the Barossa. Importantly, the aspects which cling to the hillsides and high valleys have been chosen for their true continental climate. Most enjoy warm sunny days and cool evenings. An assemblage of Shiraz from the estate's home vineyard with parcels of fruit grown to good sites lower down the Barossa Valley floor. A rich, soft, drink now expression of Shiraz, Mountadam shows the elegance of the cooler Eden Valley and the traditional richness of Barossa.

The Mountadam site was selected by founder Adam Wynn for it's myriad of interesting meso climates and geological formations. The two vineyards from the Barossa floor at Greenock Creek and Nuriootpa have had a long association with Mountadam. They are both over forty years old, family owned and have always been hand tended. Fermented over the course of two or three weeks, juices are drained from skins daily and recombined to assist in extracting colour and flavour. Each component is vinified separately and assessed to create a wine which shows a balance of fruit and tannin, alcohol and length of flavour. Mountadam is aged for a year or more in a combination of new and prior use French oak barriques.
