Bannockburn’s Shiraz is drawn predominately from vines in the south-facing Winery Block (planted in 1990) and some declassified De La Roche (planted in 2007). All sites possess soils of mainly volcanic scoria over basalt, clay and loam with a limestone clay base.
The 2019 was wild fermented with just 10% whole bunches and spent two weeks on skins before being pressed, settled and racked to French oak puncheons (10% new) for 13 months élevage. Alongside a reduction in the use of new barrels, Matt Holmes has gradually been introducing more influence of carbonic in his Shiraz. Holmes feels the mature Winery Block has inherent savoury qualities (due to the clay/limestone, old vines and poor soils) and the carbonic impact helps to lift the impression of brightness and fruit purity.
