Hi Pielle, I have a couple of specific questions regarding your recipe - hopefully no one minds me resurrecting this thread! I'm curious about the chicory root extract mentioned in your version - would this be a liquid (which I have not been able to find), or the readily available powdered version? I know that many beermakers use chicory root extract as a flavoring in their stouts, so I wonder if this is simply a tool for flavor correction (in the case of an overly sour beer, for example), or if it is indeed a part of a traditional carbonnade... I know the Belgians love their chicory root/endive... I didn't see this extract mentioned in the French-language recipe you cited - is it an innovation that you came up with? If so, I want to hear all about it! Thanks!
