In the 1840s and 1850s during the great crisis in the wine-growing sector which was characterised by devastating crop failures and a ruinous drop in prices, more and more people claimed that the wine from the Moselle must reach a better quality. That's why a textbook for viniculture written by the "Districtarzt" Arnoldi from Winningen and a viniculture map of the Trier region were published in Trier in 1868. On this map the assessment of the land registry was presented in three different colours describing the different quality of the vineyards. As an orientation for wine buyers the map quickly became so successful that the market required a corresponding map from the local government in Koblenz, too. After a long period of hesitating, this map was finally completed in 1897. Unfortunately, the official legislation for viniculture – with the law of 1892 – already focused on "Oechsle" as quality parameter at that time. So the maps became less and less important in the following decades.
