I'm making a Chocolate Milk Stout that I'm planning on adding coconut to. The cacao nibs need to be soaked in 10 oz vodka overnight according to the instructions and numerous places I've read. I've got pear vodka, habanero vodka, and cucumber vodka, but no plain vodka. I also have Bacardi Superior White Rum and Trader Vic's Dark Rum and Kahlua. I assume the alcohol needs to be at least a certain proof to work for sanitizing. Any thoughts on using any of this in place of plain vodka? Would 10 oz make a difference in flavor of 5 gallons of beer?
