Off the top of my head, I think that was about where we finished. I think we had an OG of 1.072 and an FG of 1.015. 7.5% ABV, but you wouldn't know it when you tried it.
At start of fermentation, begin soaking 4-8oz of cacao nibs in vodka. After primary fermentation is complete, add cacao nibs and vodka to fermenter during secondary (for the remainder of fermentation). We used 4oz of Ecuadorian cacao nibs along with 2oz of Dominican cacao nibs from Ethereal Confections. We replaced the idea of using cold brew coffee concentrate with using whole beans.
As far as adding the beans, we just bagged some whole beans in a sanitized mesh bag and put them into the fermenter 36 hours prior to kegging. At over 8%, we figured there was enough alcohol to combat any problems
