Chenel


Origin and cultivation background

South African-bred white wine grape cross by Prof. Offer, with Chenin blanc and Trebbiano as combination parents, released in 1974. Trials over the years have shown that Chenel is very resistant to berry cracking and rainy weather, and that it is virtually immune to botrytis and sour rot, even under the worst conditions. It has produced excellent results using intensive cultivation methods, for example irrigation and high trellising, with high yields and balanced wines that in some cases have a floral bouquet on fermentation. Although Chenel initially enjoyed active interest, particularly in irrigated regions, it has never been planted on a large scale. It is currently cultivated in all the regions, with the exception of Malmesbury. The largest concentration is found in the Robertson area, followed by Worcester.

Cultivation characteristics

Vigorous, medium-dense and well adapted to various climatic regions. Because of its resistance to rot and strong vigor, it is usually cultivated on fertile, low-lying soils under irrigation in warmer regions. Under these conditions, in conjunction with high trellising, yields of 23 to 27 ton/ha are produced when spur pruned. Fairly resistant to odium and downy mildew, and virtually immune to botrytis and sour rot. Usually produces neutral table wines with good balance.

Chenel has good compatibility with commercial rootstocks.

MORPHOLOGY

Shoot tips

Felty, white.

Leaves

Medium-sized, round, weakly three-lobed, dull green, blistered, webby underneath.

The petiole sinus is narrowly V-shaped, lateral sinuses very shallow. The teeth are slightly convex and pointed. The veins and petioles are green.
