Razor's Edge was launched with a 2004 vintage Shiraz from the McLaren Vale in South Australia. Priced to retail between $10 and $15, it brought an unparalleled pedigree and value to the American marketplace. This wine went on to receive numerous trade and press recognitions, most notably being labeled a "Best Value Wine" by Wine Spectator and as one of the "Best Buys from Australia" by Robert Parker.
In 2007, the 2005 vintage of the McLaren Vale Shiraz was released and a new wine, a 2006 Unwooded Chardonnay, was introduced. Both were very well received and demand soared after rave reviews from Wine Spectator and Wine Enthusiast magazines. Before the end of 2007, two new wines were introduced by Razor’s Edge: a McLaren Vale Cabernet Sauvignon and a McLaren Vale Shiraz Grenache.
The South Australian wine industry is responsible for more than half the production of all Australian wine. The state of South Australia has a vast diversity in geography and climate which allows the state to be able to successfully produce a wide range of grape varieties, from cool climate Rieslings in the Clare Valley, to big and full-bodied Shiraz in the Barossa. Like with most agriculture in Australia, irrigation is a vital component to the success of the South Australian wine industry. Some of Australia's most well known wines are produced here.
Vines are grown at all types of altitudes in South Australia from the low valley regions of the Barossa up to the 1,970ft vineyards in the Eden Valley. The soil type is also varied across the region from the well known terra rosa of Coonawarra, the limestone-marl based soils of the Adelaide, to the sandy, clay loam based soils of the Barossa.
