Try out the 2 Chenins of Spioenkop: Johanna Brandt that is grown on shale and matured in oak - however without loosing the cool climate freshness and acidity. Sarah Raal grows on rocky ferricrete, hence very mineral, and is matured in stainless steel tanks. So not only the underground is different, but they are also made completely different. With this package, you can taste the difference by yourself!
