## Description

This MCP server provides professional brewing tools to calculate International Bitterness Units (IBU) and the Bitterness-to-Gravity (BU:GU) ratio. It supports multiple utilization models including Tinseth, Rager, and Daniels. Use `calculate_single_addition_ibu` to find the bitterness contribution of specific hop additions, or `calculate_total_recipe_bitterness` to evaluate the balance of an entire recipe based on hop weight, alpha acid percentage, and wort gravity.

## Tools

### calculate_total_recipe_bitterness
Aggregates multiple hop additions to find the total IBU and the BU:GU ratio

### get_utilization_factors
Retrieves the theoretical utilization multiplier constants

### calculate_single_addition_ibu
Calculates the specific IBU contribution of a single hop addition

## Prompt Examples

**Prompt:** 
```
Calculate the IBU for 50g of 12% alpha acid pellets boiled for 60 minutes in 20L of wort with 1.050 gravity.
```

**Response:** 
```
The bitterness contribution for this addition is 42.5 IBU.
```

**Prompt:** 
```
What is the BU:GU ratio for a recipe with 45 total IBU and a final gravity of 1.060?
```

**Response:** 
```
The BU:GU ratio is 0.75.
```

**Prompt:** 
```
Calculate the IBU for 30g of 5% alpha acid whole leaf hops added during whirlpool in 25L of wort at 1.040 gravity.
```

**Response:** 
```
The bitterness contribution for this whirlpool addition is 4.2 IBU.
```

## Frequently Asked Questions

**How do I calculate the total bitterness of my recipe?**
You can use the `calculate_total_recipe_bitterness` tool. Provide an array of your hop additions and the final wort gravity to get the total IBU and the BU:GU ratio.

**Does dry hopping contribute to IBU?**
No, dry hopping additions contribute zero IBU as they are added after fermentation and do not undergo the isomerization process.

**Which utilization models are supported?**
The server supports the Tinseth, Rager, and Daniels utilization models to accommodate different brewing styles and wort gravities.
