I'm thinking of brewing a Vanilla Bourbon Porter. Unfortunately I don't have a spare bourbon barrels so I plan on adding about 7.5oz. of bourbon right before bottling. The beans I plan on soaking two broken apart fresh Madagascar Vanilla Beans, fully submerged in vodka for a few days, and throwing that in the secondary. Now I'm wondering will it be okay to toss the vodka and all in there after they soak? Maybe take the beans and throw them in a hop sack and toss them in there?
