PIWI Grape Varieties
(Merlot x Seibel 13666) x (Blaufränkisch x Saint Laurent)
Its clusters are medium to large-sized. Near the base of the rachis, the grape branching is relatively intensive. Berries are small to medium-sized and blue-black in colour. This cultivar is suitable for growing only in localities with a long tradition of the cultivation of red wine grapevine growing. Its successful cultivation is possible on slopes facing either south or southwest. The soil requirements of Laurot are not particular; it grows well also in vineyards with soils of medium to low quality. Laurot is a late-maturing cultivar and reaches an optimum stage of ripeness in the second half of October. This cultivar is suitable for the production of organic and varietal wines. Wine has an attractive ruby colour and shows a high content of tannins, with aromas predominated by tones of red fruit (cherry and sour cherry). In the wine of higher degrees of ripeness, it is possible also to find tones of ripe forest fruits (strawberry, raspberry, etc.).
- Cluster: The medium-sized panicle is characteristic. The grape structure is loose with short stems. The berries are small to medium-sized and round with a blue-black colour.
- Resistance: Peronospora ++ Oidium +++ Botrytis ++
- Wine: The first wines grown in our region show a deep dark colour. In terms of taste, the wines lie between St. Laurent and Merlot. The nose shows a spicy aroma of wild berries, accentuated blueberries with a soft tannin structure. Mature grape material enables the development of complex wines in international style.
- Cultivation: The first vines are planted in the experimental vineyard of the Freytag nursery in the Palatinate. In the young field on light soil, they show themselves to be very fast-growing despite the dry summer, comparable to Merlot. The grape set is two bunches per shoot. The colouring and ripeness is uniform. The harvest date in the Palatinate was in the first half of October.

Frantisek Madl in the Czech wine-growing region of Moravia. It comes from the parents Merlan (Merlot x Seibel 13666) X Fratava (Blaufränkisch x St. Laurent).
