Brewed this in 10 days for a birthday river trip. It was good, real good. Only downside: I served it alongside a pale ale that had higher abv. People chose the higher abv cause they wanted to get their buzz on. Guess it's not a problem because I brought home half a keg and am enjoying it a lot!

For an imperial stout I soaked 2 oz of light toast American oak chips in about 2-4 oz of bourbon. I added it to secondary for just three days.
