YAN Calculator
Estimate YAN demand from initial Brix and yeast strain, then calculate staged nutrient additions.
Inputs
Nutrient Plan
Target YAN
240 mg N/L
Estimated native: 127 mg N/L
YAN to Add
113 mg N/L
Based on strain demand and initial Brix.
Total Nutrients
2,303.3 g Fermaid O
611.1 g DAP
Staged Additions
At 24 hours post-inoculation: 1,382.0 g Fermaid O.
At one-third sugar depletion: 921.3 g Fermaid O + 611.1 g DAP.
Formula basis: target YAN is strain-specific and scaled by Brix. Nutrient conversion assumes DAP is 21% N and Fermaid O is 13% N.
