An essential work for winemakers and wine lovers: a portrait of all 80 native grape varieties of Switzerland. Up-to-date with the latest science: history, origin, and genetic relationships. In Switzerland, more than 250 grape varieties are cultivated on an area of just 15,000 hectares, which likely represents a world record. Among these, 80 can be considered native: human-created and spontaneous hybrids that have developed over time in the vineyards, often with origins rooted in folk legends. The Amigne from Valais is said to have been introduced by the Romans, the Completer from Graubünden was imported by Benedictine monks from Italy, and the Chasselas is believed to have originated from Egypt or Constantinople, etc. However, in recent years, DNA tests have challenged these traditional notions by revealing unexpected relationships.
