The Fermentation Yeast and Nutrient Calculator 🍇🧪 app is designed for wineries, craft breweries, enologists, and laboratory technicians who want to quickly set up a pitching plan and a YAN nutritional plan consistent with the actual data of the must.
By entering volume, °Brix, initial YAN, and dosing parameters, the tool calculates the grams of yeast needed (from pitch rate or dose g/L), rehydration water, any protective nutrient (e.g., Go-Ferm), and the amount of nutrients required to reach the desired target YAN.

What it does in practice

Calculates the yeast pitching using two methods: pitch rate in millions of cells/mL/°Brix or direct dose g/L ⚖️
Returns the total grams of yeast, the estimated required cells, mL of rehydration water, and grams of protective nutrient 💧
Determines the YAN deficit and translates it into grams of DAP and grams of complex nutrient, considering the % nitrogen of each product 📦
Suggests a fractional strategy: a portion of complex nutrient at pitching and the rest (complex + DAP) at the consumption of one-third of the sugars 📋

Why it is useful

Reduces the risk of slow or stuck fermentations
Improves yeast health and aromatic cleanliness of wine or beer
Standardizes operations and makes reproducible cellar choices
Allows customization of nitrogen percentages and distribution between DAP and complex according to available products

Technical note ⚠️

Doses are indicative and should be adapted to yeast strain, product style, temperature, and must conditions.
It is advisable to measure YAN with laboratory analysis and always follow the technical datasheets of the yeast and nutrient manufacturers.

In summary, the Fermentation Yeast and Nutrient Calculator 🍇🧪 transforms a few essential data points into a clear operational plan, helping you conduct fermentations that are safe, consistent, and aromatically clean.
