I should probably know the answer to this one... I am racking off my primary full of Chocolate Oatmeal Stout at this minute. 1 teaspoon of gelatin and five days later, there is still a large amount of cocoa in suspension. Do I need to re gelatin and crash, or just re crash? Btw, there was 8 ounces of cocoa powder in this batch, so there probably isn't a set answer.
EDIT: the first 1/2 gallon or so was "chalky" looking but, the beer coming off now is crystal clear, depending on how it settles, I will make a decision then.
