De Wet Cellar, founded on 15 April 1946, is the oldest cellar in the Worcester area. Originally, it produced about 3 000 tons of grapes annually, but over the years it has developed into a quality cellar processing around 18 000 tons annually. Since 1990, premium cultivars of red and white wine grapes have been planted on a large scale. To support the drive for higher quality, the Cellar has been modernised and has produced Champion Wines of the Worcester region several times during the past few years.

De Wet Cellar is one of only a few cellars marketing a wine with the "Heart Mark" of the South African Heart Foundation. Pettilant Fronté is a light, low-alcohol Perlé wine, full of flavour but low in calories. De Wet Cellar mainly supplies to the wholesale trade, but a small amount of selected bottled wine is sold from the premises and in local restaurants.
