Swartland
Wheatlands and Riebeek-Kasteel. The map makes it look close to Stellenbosch. The drive, and the pace of the afternoon, say otherwise.
Chenin and Rhône-style reds are what the valley is known for. Phone ahead if the visit is a working cellar rather than a restaurant.
Open a name for the reason to stop, the map pin, and the estate site. Those notes stay on the vineyard list.
