The settlements on Aach's ground date back to the Bronze Age. Later there also was a settlement of the Roman Empire. The current municipality was first mentioned in the year 953 under its Latin name Aquacuum. Despite being situated so close to the City of Trier it was not part of the Archbishopric of Trier. Belonging to the Benedictine monastery St. Irminen it was itself reichsfrei. This fact caused many Jews to settle down in Aach after they were expelled from Trier in the 16th century.
During the time of the Napoleonic Wars Aach was—according to the Treaty of Lunéville 1802—a part of France. After Napoleon's ultimate defeat in 1815 Aach became a part of the new Prussian Rhineland province. Prussia itself became a part of the German Empire in 1871.
Under nazi rule between 1933 and 1945 Aach's Jewish citizens were either forced to emigrate or murdered in the Nazi concentration camps. Nowadays there is no organized Jewish community in Aach anymore. The synagogue and the Jewish cemetery, however, still exist.
Aach is famous for its "Viez", the typical hard cider of the region.
