I am brewing a barleywine this weekend, with a target OG of 1.110-1.130, and I'm considering bulk aging in a secondary for 3-6 months. What I'm wondering is how will I know when I move to bottle it whether or not to re-pitch some yeast? I would hate to not have enough yeast to carb up the beer, but I would also hate to have 5 gallons worth of explosive beer bottles if I pitch unnecessarily.
Any opinions would be greatly appreciated!
Thanks!
