Laffort Nutrient Calculator
Goal: produce sufficient yeast biomass, without excess, and preserve a good physiological state of the yeast for the duration of the alcoholic fermentation.
| Total YAN required* mg/L | YAN added 1st addition mg/L (YAN1) | YAN added 2nd addition mg/L (YAN2) | |
| 12 % vol | 180 | 150 – Initial YAN | 30 |
| 13 % vol | 190 | 155 – Initial YAN | 35 |
| 14 % vol | 200 | 160 – Initial YAN | 40 |
| 15 % vol | 220 | 170 – Initial YAN | 50 |
| 16 % vol | 240 | 180 – Initial YAN | 60 |
For low N demanding yeasts
⇒ add 10 mg/L (YAN2) for the average N demanding yeasts
⇒ add 20 mg/L (YAN2) for the high N demanding yeast
