I've done Bourbon porters in the past and am going to approach this the same. I have always added oak chips to secondary for 5-7 days, then bottled with 675ml of bourbon, let condition for 6 weeks or so. I brewed my KBBA last weekend, came in a little low on the OG but we'll see how it turns out.
How did it turn out? Thinking about making this one soon...extract version.
