Piekenierskloof is the name wine people search for; Citrusdal Mountain is the Wine of Origin district. Altitude and old bush vines are the story, especially Chenin and Mediterranean reds. The N7 makes it reachable as a long day or a Cederberg overnight.
WineFarmz files mountain-side Citrusdal farms here, and valley-floor farms in Citrusdal Valley, using latitude and the mountain-versus-river split.
