The Wrattonbully wine region lies over several ranges in the area surrounding Naracoorte, including the Naracoorte Range (also known as the Kanawinka escarpment).[citation needed]
Wrattonbully is a cavelands region of ancient World Heritage-listed geology, which in more recent times has been chosen to establish a wine region due to its outstanding viticultural attributes like the Terra Rossa over Limestone soils and gently sloping sites creating varied aspect with altitude. [citation needed] A network of limestone caves, notably the Naracoorte Caves National Park situated in the heart of Wrattonbully, contribute significantly to the soil profiles and viticultural practices of the vineyards and the resultant quality of the region's wines.
Wrattonbully's climate is influenced by the Bonney Upwelling, a reliable ocean current of frigid water that swells to the surface each year during Wrattonbully's ripening period, providing for cooling night temperatures that help to create high quality wine grapes. Coupled with the slightly warmer daytime temperatures that Wrattonbully receives, relative to Coonawarra, it can have a wider diurnal temperature swing during the ripening period.
The first vines for winegrapes were planted in the late 1960s; however it was in the 1990s, after the test of time, that the excellent soils and elevated sites attracted many winemakers from surrounding areas to then plant most of the region's vineyards to varieties that had become proven performers like Cabernet Sauvignon, Shiraz, Chardonnay and Merlot.[6] Given that these 1990s plantings, with their modern viticultural standards for high quality wine grape production, are now reaching their maturity, Wrattonbully wine region is starting to realise its potential.
The region now draws attention from winemakers and wine connoisseurs who appreciate the region's wines for their quality, balance, tannic structure and cellarability.[citation needed] Cabernet Sauvignon, Shiraz, Chardonnay and Merlot are the main varieties grown, and Wrattonbully wines of these varieties are highly regarded for their complexity and elegance.[citation needed] More recently, the cool climate of the Wrattonbully wine region is attracting more recent experimental plantings of other varieties, like Malbec.[citation needed]
