The "Thelema Mountain Vineyards" is located on the Helshoogte Pass des Simonsberg above the city Stellenbosch

Webb in 1983 and is one of the best in the Cape region. The former accountant Webb previously studied viticulture and cellar technology at the University in Stellenbosch. The estate is now jointly owned by the founder and the McLean Family Trust. Webb was also in the process of founding the winery Spice route

The majority of the vineyards are located on the steep slopes of the Simonsberg at an altitude of up to 500 meters. The varieties Cabernet Sauvignon, Chardonnay, Merlot, Riesling, Sauvignon Blanc and Shiraz are cultivated. Premium wines from the house are "Cabernet Sauvignon Reserve" and a Merlot. Around 300,000 bottles of wine are produced annually.
