My next brew is going to be a coopers stout with 1.5kg dark lme, 300g cocoa powder and some vanilla extract. Now, I've been looking around and the only advice I can find is on adding vanilla pods (usually 2) but does anyone know how much extract I should use? I'm guessing 2 tablespoons but don't want to over do it so I'll start with 1, taste it and add more. If the flavour drops out during fermentation will it do any harm adding extract near the end of the process?
I also intend to prime with vanilla infused sugar, is this likely to make a difference?
