Probably the most famous brandy in the world is named after the city of the same name in the Département Charente immediately north of Bordeaux in southwest France near the Atlantic coast. When the Roman commander Julius Caesar (100-44 BC) conquered Gaul, his legionaries allegedly brought the Trebbiano vine from their homeland, which later became the main grape variety for cognac. According to legend, the name of the region Cognac goes back to the Roman general Comnus. The 12th century saw the advent of spriten, the process of preserving a wine by adding alcohol. It was also discovered that wine from the Cognac region was particularly suitable for distillation. Around 1530, the Dutch introduced the art of distillation in this area, they called the wine distillates "Brandewijn", from which the English term brandy was derived. At that time it was common to produce distillates by single distillation, as is still the case with Armagnac today.
