I'm making a Vintners Reserve kit, and the instructions say that once you rack it to the carboy for secondary fermentation and add the additional chemicals, you need to stir it vigorously inside the carboy. What do you use to stir inside a carboy? Even if I had a spoon long enough, it wouldn't fit inside the neck. When they say stir, do they really mean shake it? I'm thinking shaking would accomplish the same thing, but a 6 gallon carboy is gotta be pretty heavy for shaking. I'm curious what everyone else does.
