Our home run brewery is looking to morph a milk stout into a french vanilla coffee milk stout. Our thoughts are to use columbian coffee beans and vanilla bean in our grain steeping process. Though, I've heard the vodka method for the vanilla beans. We may venture that way. This being our first real brew that we've taken the reigns and drastically made our own, so we're a little unsure of about how much of each bean to use to achieve a good flavor balance. It's going to be a 5 gallon brew. Does anyone have any pointers or ratios to try out? Any sort of ideas would be appreciated. Thanks!
