Millbrook is now one of the largest vineyards established in the recently recognised wine growing region of Perth Hills. Barking owls are birds which live in the forests surrounding the estate's home vineyard. It seemed only fitting to name the wines after these noisy creatures which, on a moonlit night, can often be seen perched at the end of the vineyard rows. Parcels of Shiraz and Viognier from choice wineyards in Geographe, the Great Southern and Perth Hills are co-fermented and hand plunged for two weeks in open fermenters to extract good colour and flavour. Barking Owl has been aged in a combination of new and seasoned oak barrels for eighteen months.
