And now something completely different I discovered in the information bulletin of the Junglinster municipality in Luxembourg:
"During the Battle of the Bulge (Ardennes) the famous writer Ernest Hemingway was active as a journalist. From 17 December 1944 he stayed for three weeks in the old mill in Rodenburg. He tried to fight his thirst by emptying considerable amounts of wines belonging to Abbé N. Didier. As there was no toilet in the house, he would use the empty bottles as a chamber pot, then he would put the cork back into the bottle and write with a pencil "Schloss Heminstein" on the label.
One morning one could hear Hemingway shout and curse. In the dark of the night he had gone down to the cellar to find a thirstquencher, and by mistake, got hold of a bottle of "Schloss Hemingstein"
