Schönburger has just been registered as a own variety since 1979. It was originally to be called “Rosa Muskat”, but this was rejected by the German Bundessortenamt. This wine cultivar owes its now valid name to Burg Schönburg on the Rhine, in recognition of the wine’s region of origin. Despite its bright red berries, Schonburger belongs to the white wines, its quality is compared with Traminer. The berries have a tough skin with a wax bloom and the leaves have silky, felt-like hair.
The grape vine is a subspecies of the vine that is mainly used for the production of wine. According to the colour of the leathery skin (the flesh is non-coloured in almost all varieties), white and red wine varieties are differentiated. Wine grows naturally as a liana, but in vineyards, due to constant trimming, it grows as a climbing shrub with shoots. Wine is one of the oldest cultivated plants of mankind, the oldest evidence dates back to 8000 BC and comes from the Near East.
The berries grow in loose infructescence and can be green, yellowish, red, purple and dark blue, some varieties have a pale wax bloom. After the vintage they are sold fresh as soft fruits (often seedless, loose, large-fruited varieties) or dried as raisins (depending on the variety also “sultanas”, “currants” and “Zante currants”). Vine leaves are edible as a vegetable, they are mostly used for wrapping e.g. spiced rice, as in the case of dolmades.
The main focus of viticulture is of course the production of wine, sparkling wine and champagne. Wine is used to make brandy, liqueur wines such as sherry, port and marsala, and vinegar. As by-products grape juice (must) and press cake (pomace, marc) are produced. Pomace brandies and wines such as Grappa, Marc de Champagne and Raki are produced from this, as well as pomace vinegar. Sometimes pomace, which is rich in minerals, vitamins and fibre, is added to bread dough and used to bake a special bread. A high quality oil is extracted from the seeds. From the pomace of the seeds, nutty tasting grape seed flour is produced, which can also be added to bread and pasta doughs.
