Dear colleagues,
it is my pleasure to inform that the experiment on the Duvel clone was a success. The first quality control happened yesterday evening, after approximately 4 weeks of secondary fermentation, and the report is extraordinary. The taste is extremely similar to the original, with the only difference being the slightly darker color. I am very impressed.
If any member of the Guild wants to replicate the recipe, I would suggest to increase the wheat malt and decrease pilsner, and add the recultured Duvel yeast for conditioning. That should make the perfect clone.
