Few Australian winemakers have had as much experience with the GSM cépage as Yalumba. Originally fashioned into Ports and fortified, the exciting mix of grapes makes a multi dimensional style that's highly cherished by Barossa enthusiasts. Parcels of Grenache, Mataro and Shiraz, are collated from good Barossa vineyards, separately picked and vinified in small batches, some in oak vats and the balance in fermenters. Components are aged in a mixture of large and small vats, puncheons and smaller barrels, French, American and Hungarian oak, allowing parcels to mellow and integrate, while forming texture and increasing complexity, without any overt influence from the barrels.
