I am working on a vanilla porter in a short time frame. I have used vanilla beans in the past with certain beers and had great success. However I have a short timeline or this beer, roughly 17 days. I have a great robust porter PM recipe that I have used in the past that would go great with a vanilla addition. I am going for a pretty vanilla forward beer. Not trying to hide the vanilla at all so I picked up 4 beans at the supermarket. If I sanitize, split, and scrape these and the ad them directly to primary for 15 days assuming I am going to rack my beer into the keg to force carb for 2 days. Is the vanilla going to be over the top? I have used 2 beans in other recipes, racking the beer on to the beans and have always got VERY SUBTLE! Vanilla flavor. Let me know what you guys think?
