Clos Malverne quality grapes have the The Devon Valley’s micro climate to thank. Although the valley is shallow, it acts as a natural receptacle for the morning summer mists that linger around Stellenbosch. It’s cooler than the surrounding areas, significantly lengthening the ripening season and resulting in extremely ripe grapes. The vineyards are mostly planted on the gently sloping terrain of the valley.
Seymour recently purchased two other farms very close to Clos Malverne. One of them is Dwars in die Weg with 11 hectares under vine (Cabernet Sauvignon, Merlot, Shiraz and Sauvignon Blanc). All vines are drip-irrigated using water from the farm dam. Carlsrus has 4 hectares under vine (all Pinotage) using drip-irrigation with water obtained from Teewaterskloof dam. Clos Malverne’s 10 hectares of vineyards (Pinotage, Merlot, Cabernet Sauvignon and Shiraz) also have drip-irrigation using water from Teewaterskloof dam.
Clos Malverne uses a traditional “handmade” style of wine making. The grapes are softly basket pressed and they still use open fermentation tanks. Caps are also punched down by hand. The cellar can handle up to 400 tons although the yield from the vineyards is presently running at 350 tons per annum. French and American oak are used to mature their red wines.
