Wherever the German tongue is heard, and even further still, the king of all Rhine wines, "Johannisberger" is known and sought after. Every friend of the grape which grows on the banks of this river is well acquainted with it, but few perhaps know of its princely origin. It is princely, not because princes' hands once kept the key to Johannisberg, but rather because princely hands planted the vine in the Rhine country, and this royal giver was no other than Charlemagne, the all-powerful ruler of the kingdom of the Franks.

Once in early spring Charles the Great was standing on the balcony of his castle at Ingelheim, his eyes straying over the beautiful stretch of country at his feet. Snow had fallen during the night, and the hills of Rüdesheim were clothed in white. As the imperial ruler was looking thoughtfully over the landscape, he noticed that the snow on one side of Johannisberg melted quicker in the sun's rays than on any other part. Charles, who was a great and deep thinker, began to reflect that on a spot where the rays of the sun shone so genially, something better than grass would thrive.
