Description
The identification is based on:
- the tip of the young shoot with a high density of prostate hairs,
- the yellow young leaves with slightly bronze spots,
- the shoots with red or red-striped internodes,
- the circular adult leaves, with five or seven lobes, deep U-shaped lateral sinuses, a petiole sinus with overlapping lobes, medium teeth with convex or straight sides, a weak to moderate anthocyanin coloration of veins, a slightly goffered leaf blade, and on the lower side of the leaves, a medium density of erect hairs and a low density of prostate hairs,
- the slightly obloid berries.

Phenology
Bud burst: 5 days after Chasselas.
Grape maturity: mid-season, 3 weeks after Chasselas.
Suitability for cultivation and agronomic production
Riesling has good resistance to winter cold andits fruitfulness after spring frost is good. This variety must be pruned long and trained. It is a little sensitive to dessication of the stems. Its ideal terroirs are varied (limestone, granite) but are mainly made up of schist.
Sensitivity to diseases and pests
Riesling is sensitive to grey rot, anthracnose and grape moths. Under certain conditions, grey rot attacks on the peduncles can lead to early grape drop.
Technological potential
The bunches and berries are small. Riesling produces great quality dry white wines: very aromatic, lively and elegant. The acidity balance is very high. These wines are suited to ageing and their bouquet evolves slowly towards "petroleum" (hydrocarbons) aromas. Riesling, when over-ripened or in the presence of noble rot can produce great liqueur wines.
Clonal selection in France
The eight certified Riesling clones carry the numbers 49, 1089, 1090, 1091, 1092, 1094, 1096 and 1097. A conservatory of almost 190 clones was planted in Alsace in 1997.
