Notes

Use blow-off tube for initial fermentation.

Rack to secondary after 1 week: soak oak cubes, cocao nibs, Godiva, and Grand Marnier the night before racking to secondary; add mixture directly to beer. Bottle after 2 weeks. Age for at least 90 days.

If all targets are met, the addition of the liquor mixture will raise the ABV to approximately 10 - 10.5%
