Corey Ryan spent two decades crafting the most memorable vintages at Henschke, Penfolds and McWilliam, not to mention tours of duty in la Vallée du Rhône, he understands old vine Shiraz very well. Kym Teusner shares Ryan's devotion in the pursuit of resuscitating very old, low yielding, dry grown vineyards, Teusner honed his own artisanal approach under the tutelage of grand masters Rolf Binder and Torbreck. Zeppelin is the Messrs Ryan & Teusner bond, to capture the splendour of old vine Shiraz and make it accessible to all Barossa enthusiasts.

The conspicuously low yields of some great old Barossa vineyards makes their fruit unviable for commercial brands. Only the most skilled and knowledgeable small batch winemakers have the dedication to handle such precious parcels of old vines fruit. Shiraz is picked off a single site in the Angaston foothills, planted to sand over clay soils, growing at an elevation of 275 metres. Fruit is crushed into traditional open top fermenters and treated to a course of manual pumpovers, twice daily throughout the vinification. Upon completion, batches are basket pressed and racked into a selection of seasoned oak barrels for an extended term of twelve to eighteen months, to be bottled without fining or filtration.
