I am wanting to add maltodextrin to my latest creation for head retention and body. I do not know how much to use in the bottling bucket. I have an 8oz pkg and my local store told me to dissolve the entire pkg in 2 C water and add with my simple syrup. I have read on some online resources that 8oz is too much and I should use 4-5oz. What are your thoughts and what have you done in the past?
