On Wednesday 3 September 2025, Brasserie Nationale (Bofferding National Brewery) announced the release of two collector’s glasses to mark the 25th anniversary of the reign Grand Duke Henri and the accession to the throne Hereditary Grand Duke Guillaume.

From Monday 1 September, 12,000 copies of the limited-edition glasses have been available in shops across the country.

The glasses include the official monograms in prominence, accompanied by silhouettes of the Palace and Château de Berg, with green and gold finishes reflecting the colours of the celebration.

In its statement, the brewery said: “Brasserie Nationale, an independent brewery, had already taken an active part in the change of reign in October 2000. True to its local roots and attached to the country’s history, it is proud to share this celebration with all Luxembourgers, a moment that will leave a lasting mark on the collective memory.”

The brewery added: “Bofferding is thus pleased to contribute to the festive moments of the Trounwiessel, which will bring together the population on Friday 3 and Saturday 4 October 2025.”
