Soaking raw cocao beans in vodka...should I add more?

I am getting ready to brew a Chocolate stout. I have just put it into the primary. I plan on putting some raw cacao beans into the secondary. I crushed them into chunks and am soaking them in vodka for a week to extract the flavors. In total I am using 10oz of beans. I put them into a container and covered them in vodka last night. It was actualy quite a liberal amount of vodka too just to cover the beans. This morning I woke up and just about all the vodka has been soaked up by the beans! Should I add more to re cover them? I am afraid of putting alot of vodka into my brew but I dont want the beans to get ruined. Any one else experience this?

If you only covered the beans, you should be OK to add a bit more vodka. You want enough in there to create an infusion of the chocolate flavor. I did this with vanilla beans and used an entire 750 of vodka. After about 4 weeks, I had the richest vanilla extract I've ever had.

You're afraid of getting alcohol in your brew?

You'll have to add more, because otherwise what is in the beans will stay there.
