The Limestone Cost comprises a few sub-regions you've likely already heard of, such as the acclaimed Coonawarra. But in amongst the known are some hardly knowns that you may miss, and shouldn't.
Wrattonbully, Mount Benson and Padthaway – feel free to read up on these in more detail, but here's an overview.
With vines dating back to the 1970's, Wrattonbully grew to fame in the early 90's when larger producers like Hardy's and Beringer Blass began planting. Primarily a red region, with shiraz and cabernet sauvignon in quantity.
Mount Benson, first planted in 1989, is a newcomer to the South Australian industry. It has quickly established itself as on par with it's older cousins, producing excellent cabernet sauvignon, shiraz, and chardonnay. Cool ocean breezes aid in producing complex, deeply flavoured wines.
Padthaway, like the Coonawarra, has the same red-gold soil, but warmer temperatures overall. Similar in climate to the Bordeaux in France, cabernet sauvignon and chardonnay do well here, with vines established in the 1960's.
