William Formby was among the early ardent pioneers of Langhorne Creek, he planted his first acreages of vine in 1891. Today his progeny still husband vines, the Adams of Langhorne Creek, are at the cutting edge of regional viticulture. Fruit is harvested from some of the most noble blocks on the Metala estate, to be fashioned into the enduring style of Aussie Cabernet Shiraz, a suitable match to roasts, stir frys or grills.

Legendary winemaker Brian Dolan won the inaugural Jimmy Watson Trophy in 1962 with the 1961 Metala Vineyard Shiraz Cabernet. The best fruit from the historic Metala property is now reserved for the estate's own Brothers in Arms and Formby/ Adams, as well as a number of well known labels and smaller boutique wineries such as Oddfellows and Killibinbin. Cutting Edge is a mostly Cabernet wine with a portion of Shiraz, grown and vinified to a mix of traditional and modern vineyard management and winemaking practices that produce the best possible wine from the famous Metal Vineyard. Matured for fifteen months in a combination of one to four year old French and American oak barrels.
