Brand ABV is the target packaged ABV % (e.g. 5.2% → enter 0.052). Used to verify spin target alignment. FV ABV is the actual measured FV gravity-derived ABV. Target Spin ABV is what you want to dilute down to before packaging.

Beer Yield = FV Vol × Efficiency
Total Brite = Yield × FV ABV ÷ Target ABV (= Corrected Volume)
Corrected Gravity = Yield × FV Gravity ÷ Corrected Volume
DAW Required = Total Brite − Beer Yield

Post-Skid Target = ((DAW Req × (Batch Carb − DAW Carb)) ÷ Beer Yield) + Batch Carb
Beer Carb Skid SP = (Post-Skid Target − FV Carb) × 200

LGB Skid SP = (High Carb Target − FV Carb) × 200
BBLs to Carb = Beer Yield × (Batch Carb − FV Carb) ÷ (High Carb − FV Carb)
BBLs to Bypass = Beer Yield − BBLs to Carb
Est. Final = (High×Carb_BBLs + FV×Bypass_BBLs + DAW_Carb×DAW_Req) ÷ Total

Base Beer = Req. Finished × Target ABV ÷ FV ABV  ·  DAW = Req. Finished − Base Beer
