Kloovenburg stretches along the lower contours of Kasteel (Castle) Mountain, where the north-easterly slopes have proved ideal for the Shiraz and Cabernet Sauvignon cultivars and the south-westerly and easterly slopes favour Shiraz.
The anecdote that best illustrates the meticulous nature of viticulturist Pieter du Toit is that of the vineyard block which had been laid out against a steep slope of Kasteel Mountain. Though no one else noticed that the rows of vines had been planted slightly crooked, this bothered perfectionist Pieter who spared no effort through days and days of hard work, ensuring that the block was straightened to meet his stringent standards. Today this vineyard block is still called “die skewe blok” (the crooked block) although now of course, the rows are perfect.
