I have made a few brews so far but am a relitive newby at home brewing and would like some advice. I have been toying with the idea of adding some grain to my next brew just for a change but am unsure of the method! Should I be substituting Dextrose with the Grain or should I simply be adding the grain to the final mix?
Yup, that's all you need to do. Don't take anything out of the original recipe, just add a few pounds of grain for variety. It will give you a MUCH broader range of options when making a batch and you will be very glad you did it.
