So I'm about to brew my third batch tomorrow and the instructions for my previous as well at this one say to seal the fermentor and shake vigorously for several min. The last two batches I covered the carboy with a piece of sanitized aluminum foil and shook vigorously for several minutes this seemed to work well but I'm not sure if it's really the right way to go. I really don't want to pour it back and fourth and I don't have an aeration system so is my method ok or does anybody have any better suggestions....thanks for any advice...!!
