Prüm Abbey
It is believed that vines were cultivated in the Ahr valley already in Roman times, as is the case with nearby Mosel, although definite documentary evidence to this effect seems to be lacking. However, a property list of the Benedictine Prüm Abbey drawn up in the year 893 AD, called the "Prümer Urbar", lists vineyards in eight Ahr locations, so at least at this time, winemaking in the Ahr region was established.
