Hi all. I use Beer Alchemy for Mac. When making a new recipe, it asks for my "volume before boil," and "volume after boil." It is defaulted for 6.08 gallons before boil and 5.25 gallons after boil. However, when I boil, I boil 1.5-2 gallons of water, add the DME, and when the boil is done, I add it to a carboy that has 3 gallons of water in it. The software also has a spot for "water added to dilute." Is that the water you add to top it off?? I didn't pay much attention to these figures, but if I set them to my start of boil (1.5-2) and end of boil amounts, my numbers, such as IBU are significantly affected.
