Narrative

Per Winkler (see citation): "Gray Riesling bears the name but is lacking in the genuine aromatic qualities of the Riesling. It is grown in Europe prnicipally in the Arbois region of France. Its product has a mild spicy flavor, but little mroe. Its vine and fruit characters, except for less fruit color, bear a fairly close resemblence to the Trousseau. The variety is a strong, vigorous grower. It produces well with head-training and spur or cane pruning. The clusters are small to medium in size; slightly conical; compact. The berries are medium; long oval; dull reddish-tan. The clusters are small to medium in size; slightly conical; compact. The berries are medium; long oval; dull reddish-tan. The leaves are small; rough; only slightly lobed. The canes are semierect, with short internodes." Information taken from http://www.wine-lovers-page.com/wineguest/wgg.html: "Mutation of the Trousseau vinifera grape grown in France. Currently known in California as Grey Riesling and mainly used in a white wine blend that also contains some Chenin Blanc and Sylvaner varietals." Unknown Source: "Clusters: medium-small in size, about 1/5 to 1/3 lb; shouldered and slightly conical, compact. Berries: Medium in size, long oval, with very firm texture; greenish-pink to dull reddish-tan; flavor neutral to mildly spicy. Growth and Adaptability: A very vigorous, upright growing variety with abundant foliage. Canes are thick with rather short internodes. Adapted to a wide range of soils. The vines leaf out fairly early in the spring. A good producer at 5 to 7 tons per acre. Harvest period: One of the earliest wine grape varieties to ripen - late August to early September. Training and Pruning: Bears well with spur pruning. Special Insect and Disease Problems: The bunches are quite susceptbile to Botrytis bunch rot; this problem is aggravated by dense foliage and heavy massing of fruit. Young shoot growth in the spring is susceptible to stunting after heavy feeding by flower thrips."
