Billy Goat Hill Estate 2013 Cabernet Merlot. Billy Goat Hill, with its granite out-crops on gravelly loam soils, is set within the beautiful Darling Ranges of the South West of Western Australia. This secluded local landmark on the outskirt of the town of Harvey bares the name of this range of fine wines. Following a warm vintage and gentle maceration of skins during alcoholic fermentation, the finished wine shows good intensity of cherry and blackcurrant fruits combined with fine tannins.
