Candle in the authentic Orval Trappist beer glass designed by the Antwerp architect Henri Vaes. Did you also know that you can see exactly when it was blown on the glass? It was an idea of the monks themselves, and dates back to 2012. So that if something ever goes wrong with a glass, they can immediately take the entire lot off the market. Even the most fervent fans don't seem to know. You can already challenge your bar companion with it next time. There's a good chance that he won't find the solution. And will search like crazy. Everything is hidden in the 'L', the last letter of the beer brand on the beer glass. Four numbers are hidden in the flat line. Two of the production year, two of the production batch. If you drink from a '20 03', that is a glass from the third production of the year 2020. Once you've seen it, you can't ignore it.
