I'm new at brewing, and I'm going to try to make either Chocolate Stout or Porter in my Mr. Beer kit. I have been reading related post, and I will probably soak the nibs (4 oz.) in Vodka the night before. My question is... can I put the nibs in my primary, and if so, when? After the boil, before I pitch the yeast, after I pitch the yeast, or sometime after the fermentation begins. Also then how long should I let it sit before bottling? I do not want much bitterness in the final product. I'm really not familiar with the secondary process and would rather keep it as simple as possible. Thanks ahead for the comments.
