The Riesling Renano grape variety originates, as its name suggests, from the Rhine Valley in Germany. In this region, and especially in the Mosel area, Rheinriesling is widely cultivated and produces extraordinary wines, particularly in the forms of late-harvest and passito wines, often enhanced by the contribution of noble rot, leading up to the famous Eiswein. Rheinriesling is the most important grape variety in Germany and holds a position there comparable to what Chardonnay represents for France. Its name might derive from the expression “Reissende Tiere” (“wild animals”), reflecting its origin from domesticated wild vines. Rheinriesling is widely grown throughout Central Europe, in Austria, Hungary, Slovenia, and Croatia. In France, it is cultivated in regions bordering Germany, particularly in Alsace. The introduction of Rheinriesling to Italy is relatively recent, occurring between the late 19th and early 20th centuries.
In Italy, Rheinriesling is primarily grown in Trentino-Alto Adige, Oltrepò Pavese, Veneto, and Friuli-Venezia Giulia. The best Rheinriesling wines in the country are undoubtedly vinified in Alto Adige, where the climate provides all the conditions necessary for optimal grape ripening. One of the unique traits of Rheinriesling is its remarkable resistance to cold, making it suitable for cultivation only in regions with rather harsh climates. In Italy, it performs exceptionally well near the Alpine arc. This resilience is due to the extremely hard wood of its vines, enabling them to withstand the very low temperatures typical of Central and Eastern Europe. Its budding and ripening are late, which helps protect its buds and clusters from spring frosts, although it can be affected by flower drop.
A key characteristic of Rheinriesling wines is their predisposition to aging, maintaining their intense and penetrating aromatic profiles over time. The wines exhibit equally bold flavors, particularly minerality on the palate. This is due to both their pronounced acidity and high sugar concentration, making their sweet wines highly renowned and celebrated. The olfactory profile of Rheinriesling is complex and penetrating, as it is an aromatic grape variety with a high content of terpenic compounds. The aromas include ferrous, floral, and honeyed notes, which, with long aging, develop distinctive hydrocarbon nuances, one of the most sensational scents associated with this wine.
