I've given this some thought over the weekend and here's where I am. I am still getting some activity in primary so I'm going to leave it alone for another couple of weeks. I put 1.5 oz of Hungarian oak cubes (medium toast) in a Mason jar and covered it with bourbon. In two weeks or so, I'm going to rack the stout to secondary in a 5 gal better bottle. At that point, I'll dry hop it with the Fuggles and add the oak cubes. From that point on, I'll play it by ear. Hoping to let it condition for several months.
If all goes well, sometime late spring/early summer, I'll bottle and let it condition for another couple of months. Crack open a bottle next Halloween to see where things are. Does that seem like a reasonable time line?
