Assuming he is correct, and 10% will work ...Primavera wrote:Apologies if this has been answered elsewhere...
I have access to locally malted 2-row. I have brewed two batches so far and my GIB has been 10 points lower than expected.
My LHBS confirmed that this was typical for this malt and suggested to use 10% more grain for this malt to make up for the lower efficiency.
How should this be handled in BIABacus?
Write down your original base malt quantity.
1. enter or convert your grain bill to grams (read: not percentages).
2. add 10% to base malt only
3. increase the OG on the right side of section C. "OG override" (leaving the left side the same), keep making it greater until all the grains match on both sides.
you can use more decimal places than are shown, like ... 1.07359
I've never actually done that, but that'll allow the biabacus to account for his instructions. Be sure to write a note in Section I as to why you did this.
