I've done a little research by reading some old threads, but I was looking for some specifics. I have an imperial porter in my primary right now. I want to add something extra to my secondary. I thought of vanilla beans, cacao nibs, or coffee. I think I'm going to go for the vanilla beans. I've read you should sterilize them in some alcohol, ie vodka. I need to know how long. Does the vodka leech out any of the flavor? Should I just pour the vodka and beans into the secondary? Looking for any input from those who have tried. I'd also like to try some bourbon soaked cacao nibs for an upcoming brew.
