The winery "Thelema Mountain Vineyards" is located on the Helshoogte Pass of the Simonsberg above the city Stellenbosch
in the eponymous South African wine-growing district. The name Thelema means philosophically "will". The former fruit farm was founded as a winery in 1983 by Gyles H. Webb and is one of the best in the Cape. The former accountant Webb previously studied viticulture and cellar technology at the University of Stellenbosch. The estate is now jointly owned by the founder and the McLean Family Trust. Webb was also at the founding of the winery Spice route
(Swartland). In 1994, he was voted "Winemaker of the Year". The total property comprises 155 hectares, of which 55 hectares are under vines. The vineyards are mostly on the steep slopes of the Simonsberg in up to 500 meters above sea level. The varieties Cabernet Sauvignon, Chardonnay, Merlot, Riesling, Sauvignon Blanc and Shiraz are cultivated. Premium wines of the house are "Cabernet Sauvignon Reserve" and a Merlot. Every year around 300,000 bottles of wine are produced.
