Zinfandel

The origin of this variety has been much written about. It was introduced to California from Austria under the name Zinfandel in the early 19th century. In the 1970s, it was identified with Primitivo in Pouilles, where it was introduced from Croatia in the late 18th century. In 2011, its original name in Croatia was found: Tribidrag. DNA tests have also shown that it's a parent of Plavac Mali, the most widely grown red grape variety in Croatia. In Switzerland, this early variety with high alcohol levels has only a minimal presence.

Divona

A crossing between Bronner (a German varietal) and Gamaret, the white Divona grape is the result of 20 years of patient and meticulous selection by Agroscope. The Divona has a very good wine potential and a resistance to gray rot thanks to Gamaret. The grape of the Bronner protects it strongly against the mildew and the powdery mildew (diseases caused by mushrooms).

Divona (codename IRAC 2060) was selected among thousands of applicants on the basis of both vine and wine criteria: disease resistance, adaptation to climate, production capacity and sugar content. This new grape shares the same parents as the red Divico who is already enjoying a promising development.

Barbera

Barbera probably originates from somewhere between Lombardia and Emilia-Romagna (I). It wasn't until after the phylloxera crisis in the late 19th century that it became widespread in Piedmont, particularly in the Alba and Asti regions. A productive variety, producing wines that are rich in colour and alcohol, with minimal cultivation in Switzerland.

Diolle

Diolle is an old variety of Valais (Switzerland), recorded for the first time in 1654 around Conthey. Until 2007, Diolle was thought to have disappeared, until two surviving vines were discovered in a wall at Savièse. DNA tests indicate that it is an offspring of Rèze. This revived variety was planted by Didier Joris and José Vouillamoz in 2015, so we will have to wait until 2018 for the first wine from this "new old" variety of Valais.
