Located in the McLaren Vale in South Australia, d’Arenberg has existed in one form or another since 1912, when Joseph Osborn purchased nearly 75 acres of vineyards. Four generations later the winery is still owned by the Osborn family, now headed by Chester d’Arenberg Osborn. The d’Arenberg wines were winning awards as early as the late 1960s, and today they are among Australia’s most admired and award-winning wines. Although the estate makes a variety of red and white wines, its signature wines are Shiraz, Cabernet Sauvignon and Grenache/Shiraz/Mourvedre blends. The Dead Arm, a 100% Shiraz, is one of d’Arenberg’s most admired wines. Its unusual name comes from a fungus disease that affects vineyards and results in a “dead arm” on the vine, which means extremely concentrated grapes are produced on the unaffected side of the vine. Also noteworthy is d’Arenberg’s The Coppermine Road 100% Cabernet Sauvignon.
