Hello! I feel bad that I scarcely post here and don't check up on posts promptly enough but the truth is I don't get to brew that often either. I began my brewing journey around the same time as I started my fatherhood journey so that's just how it goes I suppose... I had a question regarding adjusting OG in BIABacus. I'm brewing Zainasheff's Chocolate Hazelnut Porter but I want to bump up the gravity because I tried a CHIP that was so good I must try to recreate it. Anyway when I enter in the "For this batch, I'd like to try an OG of" it adjusts every grain in the bill including those marked for "Steep only." My understanding has been that if you want to increase gravity without changing flavor and color characteristics from the kilned grains then you increase ONLY the base grains. When using a recipe one would not want to change the specialty grains unless changing the volume of beer they were wishing to produce. I'm sure there are debates about this but I believe I read it in BCS which seems to be a sort of bible around here. I do wish to use this method for now and am wondering if BIABacus has a way to do this or if I'm just going to have enter in my desired gravity calculate new percentages based on the adjusted base grain measurements and make a new BIABacus file with an altered grain bill. (I'd considered just adding additional grain rather than go through the trouble of documenting but thought it would make it difficult to track my numbers and I don't wish to diminish the usefulness of BIABacus.
As always I appreciate your collective wisdom.
