In the 1970s, Yalumba made a far sighted decision to establish its own vine nursery. Today it is one of the nation's largest, supplying vines to winemakers from coast to coast. Y Series is sourced from vineyards with can yield grapes worthy of the Yalumba moniker. The label depicts Yalumba's very own coopers toiling at their craft of fabricating oak barrels, a proud tradition within an industry that can find few of these truly gifted artisans. Choice parcels of Shiraz, destined for Y Series are vinified in a mix of static potters and rotary fermenters. Warm temperatures at the onset of vinification and several days of post ferment maceration extract soft fleshy tannins and build structure.
