A couple of years ago, I wanted to quickly free up a keg, so I combined the remaining half of a Kentucky Bourbon Barrel Ale clone with the remaining half of a Pumpkin Ale, and it was quite delicious. I am going to try to do something similar this year as a single batch, but I haven't quite figured out the details. I think I will make a basic Pumpkin Ale, and after primary fermentation, split the batch into 2 secondaries. In one, I will add bourbon and an oak honeycomb, and in the other, I will add cinnamon sticks and a scraped vanilla bean and let them sit for a couple of weeks. I could probably do it all in the same secondary, but I want to see how the flavors develop independently over time.
