Boys,
I taylored this calculator to be used with all of NB's kits. Just select your kit in the pull down menu and input the beer temp and volume. If you know the volume of CO2 you want you can input that instead of using the pulldown menu.
This breaks down the quantities into weights (best) and cup volume (worst). I have include many different sugars.
Any questions or problems let me know.
