Pedemontis, Arajs, Roero Arneis DOCG. Ancient white grape variety cultivated since 1400 in the Roero. For century vinified sweet or in vermouth version, it experienced a period of splendor linked to the European royal courts, and then risked extinction towards the early 1900s when, due to its difficulty in being cultivated and poor yield, it was almost abandoned in favor of more generous and easier to grow grape variety such as Chardonnay. Since the late 60s of the twentieth century, it has experienced its rebirth and enhancement, thanks to dry and pure winemaking. Today, it is the Piedmontese white wine par excellence.
