The 19th century De Wet farm is located in the picturesque Robertson Valley, nestled between two rugged mountain ranges near the Breede River, where it benefits from ideal conditions to breed horses and grow vines. Historically, the farm had three activities: horse and ostrich breeding and vine growing, but today winemaking is the main activity. Owning 220 hectare of their own vines and having a bottling line on site has allowed the winery to control the making of its wines from start to finish.
For 60 years the Excelsior land was grazed by thoroughbred horses because of the limestone rich soils which contribute to bone strength. These soils have also been found to be highly beneficial to grape growing as the grapes from these vineyards display greater spice notes in reds and minerality in whites than what is typically found in the Robertson region.
