je mets les infos trouvés si cela peut intéressé quelqu'un :

You can add the nibs to the end of the boil for a small amount of chocolate flavor and aroma, or add them to either the end of the primary or in the secondary fermentor. The best way that I have found to impart the most the character from the nibs is to soak them in vodka for 24 to 72 hours prior to adding them. You use just enough to cover the nibs amount you want to use. For example, if you use 6oz for a batch of beer, the amount of vodka it takes to the cover the nibs in a small container is not enough to alter the ABV by anything you can detect by taste or smell. You do add the nibs and vodka to the beer. Just remember, only add enough to cover the nibs, no more than that.

So why the vodka you ask? Because there are volatile components to the chocolate that are not soluble in water. So for better extraction of the flavor and aroma qualities of the nibs, you need a medium like alcohol to draw them out. Vodka is neutral enough to do the job, while not affecting flavor or aroma in the small amount used for a 5 gallon batch of beer. Another benefit is that the vodka is high enough in alcohol to sanitize the nibs prior to adding them to the primary or secondary fermentor.
