## Description

This MCP server provides enologists with precise tools to manage yeast nutrition during fermentation. Use `calculate_yan_deficit` to determine if current nitrogen levels meet the requirements of your specific yeast strain and sugar concentration. For immediate needs, `plan_dap_supplementation` generates a safe, staged addition schedule for inorganic nitrogen. For long-term yeast health, `optimize_organic_strategy` provides a nutritional plan using organic sources, while `evaluate_fermentation_risk` offers a qualitative assessment of potential stuck fermentations or H2S production risks.

## Tools

### calculate_yan_deficit
Determines if the current nitrogen levels are sufficient for the planned fermentation

### evaluate_fermentation_risk
Provides a qualitative assessment of the risk of stuck fermentation or H2S production

### optimize_organic_strategy
Provides a long-term nutritional plan using organic nitrogen sources

### plan_dap_supplementation
Calculates the specific amount and timing for inorganic nitrogen (DAP) additions

## Prompt Examples

**Prompt:** 
```
Calculate the YAN deficit for a must with 24 Brix, 150 mg/L initial YAN, and a strain demand factor of 1.2.
```

**Response:** 
```
The required YAN is 288 mg/L, resulting in a deficit of 138 mg/L.
```

**Prompt:** 
```
What is the risk level for a fermentation with 100 mg/L YAN and 25 Brix using a strain factor of 1.5?
```

**Response:** 
```
The risk level is High due to High Sugar Demand.
```

**Prompt:** 
```
Plan a DAP supplementation for a 50 mg/L deficit over a 7-day fermentation with a target rate of 1.0.
```

**Response:** 
```
Total DAP needed is 50 mg/L. The schedule is: Day 1: 25 mg/L, Day 3: 15 mg/L, Day 5: 10 mg/L.
```

## Frequently Asked Questions

**How do I know if my nitrogen levels are sufficient?**
You can use the `calculate_yan_deficit` tool. By providing the initial Brix, current YAN, and the yeast strain demand factor, the tool will tell you if your levels are sufficient or if a deficit exists.

**Can this tool help prevent stuck fermentations?**
Yes. By using `evaluate_fermentation_risk` and `plan_dap_supplementation`, you can identify high-risk scenarios and create a controlled nitrogen addition schedule to support yeast health and prevent stalls.

**What is the difference between DAP and organic supplementation?**
DAP is an inorganic source used for rapid nitrogen boosts via `plan_dap_supplementation`. Organic sources, managed through `optimize_organic_strategy`, provide a more gradual and sustained nutritional profile for long-term yeast vitality.
