I'm doing a robust porter the Saturday before the Superbowl and my wife asked if I could do an oak bourbon porter, so I'm going to make a 10 gal batch and split off 5 gal for the oak bourbon. Never used oak before. I remember from a session that cubes were better than chips so have cubes on the way. Also plan to soak the cubes in the bourbon.
Question is how much oak and for how long? I know it's to taste and will be testing but need a good baseline. Will put it in late in the primary (usually let the porter sit in primary for around 3 weeks, no secondary) or in the keg.
Suggestions?
