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"
