The first settlers to cultivate the virgin land of the estate now known as Hartenberg were in 1692. Today the winery remains in the safe hands of the Mackenzie family who took over in 1987 and have been following their vision, to do whatever it takes to produce wines of outstanding quality.
Hartenberg is nestled in its own valley on the free-draining, north-eastern slopes of the Bottelary Hills. Vineyards face north, west, and east, with varietals planted to take advantage of either morning or afternoon sun. There is a difference in altitude of some 250 meters between the northern and southern vineyards.
