Excelsior is a Robertson winery in South Africa's Breede River Valley, where the region's warm days and cool nights shape distinctive white and red wines. The winery's Viognier expresses the aromatic character typical of the variety—stone fruit and floral notes with textural depth. The Chardonnay Stablemate demonstrates the region's capacity for balanced, age-worthy whites, while the Syrah captures the dark fruit and spice that Shiraz achieves in Robertson's terroir. Wines from Excelsior have been assessed by Wine Advocate, Wine Spectator, Wine Enthusiast, Falstaff, and Decanter.
