How is the bitterness calculated?

Bitterness is calculated using the Tinseth formula, which accounts for hop weight, alpha acid percentage, boil time, and the original gravity of the wort.

What determines the color of the beer?

The color is determined by the Malting Color Units (MCU) of the grain bill, which is then converted to SRM using the Morey equation.

Can I predict evaporation loss?

Yes, you can use the `simulate_boil_process` tool to predict the final volume and total volume lost based on your boil-off rate.

This MCP server provides precise brewing calculations for beer production. Use calculate_bitterness to determine the total International Bitterness Units (IBU) and the specific contribution of each hop addition based on the Tinseth formula. Use calculate_color to predict the final SRM color and its descriptive classification (pale, gold, amber, copper, or dark) using the Morey equation. Additionally, simulate_boil_process allows you to predict volume loss due to evaporation during the boil.
