Technological potential
Certified ENTAV-INRA® Gewurztraminer grapevine produces intensely aromatic wines with rose and lychee notes. Suited to cool, marly terroirs. The bunches and the berries are small. Gewurztraminer has a good sugar accumulation potential and in favorable terroirs, produces excellent quality wines, moderately acidic, full-bodied and generous with powerful and particular aromas (rose, litchis). These aromas tend to become heavier and less eleganat in warm climatic zones.
Cultivation and agronomic skills
This variety is of fairly high vigor, not very productive and sensitive to coulure. It must be pruned long. Gewurztraminer is rather demanding regarding terroir (preferably marly), and is sensitive to chlorosis. It is also sensitive to dessication of the stems. This relatively early variety is sometimes affected by spring frosts but resists well against winter frost.
Description elements
The identification is based on:
– the tip of the young shoot with a very high density of prostrate hairs,
– the small adult leaves, with three lobes, a slightly open or with overlapping lobes petiole sinus, short to medium teeth compared to their width at the base with convex sides, a low to moderate anthocyanin coloration of veins, a blistered, slightly goffered leaf blade, twisted or revolute on the edges, and on the lower side of the leaves, a medium density of prostrate hairs,
– the round-shaped berries with a pink (purplish) skin when ripe.
