Pertaringa is surrounded by magnificent stands of native gum trees. All vines are pruned to control vigor and crop levels using a combination of regimens. In the summer the vines are topped and trimmed cutting the shoot tips off to encourage lateral growth and make the vines easier to access. Ironically, Pertaringa's Shiraz was initially sold off to Hardy Wines, proprietor Geoff Hardy's family company, to make port and to exchange for other wines as payment. Today Pertaringa's old Shiraz vines make the finest full bodied reds of the region and are highly sought by leading companies for their flagship wines. The most superior parcels of estate fruit are set aside for the Pertaringa label.
