In 1981, Hermann Gebers bought the farm now known as Post House, planting vineyards throughout this beautiful property. Nick Gebers made a few barrels of wine as an experiment in 1996. Two vintages later, and after a stint in Burgundy, the first vintage was released. The homestead once served as a post office for the missionary community of Raithby, giving this winery its name. As of 2009, the vineyard comprises of Cabernet Sauvignon, Merlot, Shiraz, Petit Verdot, Pinotage, Chenin Blanc, Sauvignon Blanc and a sprinkle of Viognier. The objective is to interfere as little as possible in the winemaking process. They use traditional methods including natural yeast fermentation, basket pressing and no fining or filtering, resulting in perhaps the darkest coloured wines to be found anywhere.
