I brewed the all grain Bourbon Barrel Porter kit for the first time, and looking ahead to getting it bottled. I haven’t found a specific suggestion for carb level, but I was thinking ~2.3 volumes CO2. How does that sound?
2.0-2.4 would be a good level in my book. That can be a tough beer to carbonate because of the top layer of vanilla or bourbon so make sure you give it a little jiggle once or twice. Once you break that barrier, it should carb just fine.
