I want to bottle half and keg half of my Pumpkin Ale. I need to naturally carb both because of the lack of fridge space in my apartment. I am not looking to start a debate on natural Vs. force carbing a keg, i just want to know how much corn sugar to use in the keg because of the large head space. I am not sure if it will make a difference in carbing. Half of me thinks using the normal amount of corn sugar (for kegging) will do fine and it will equalize over time. the other half of me thinks it will require more corn sugar, close to the amount used to bottle. Any Thoughts?
