Calculate ABV, attenuation, calories, and beer style from gravity readings.

3 tools Official Updated Oct 1, 2026 Official Vinkius Partner

This MCP server provides precise tools for homebrewers to analyze fermentation data. Use calculate_abv_metrics to determine alcohol content, apparent attenuation, real extract, and caloric density. You can also use convert_gravity_units to switch between Specific Gravity and Plato, or validate_fermentation_sanity to ensure your gravity readings are physically realistic.

convert_gravity_units

Converts a gravity measurement between Specific Gravity and Plato

validate_fermentation_sanity

Checks if the provided gravity readings are physically possible in a brewing context

calculate_abv_metrics

Calculates primary fermentation metrics including alcohol content, attenuation, and caloric density

Calculate the ABV and metrics for a beer with an OG of 1.060 and an FG of 1.012.

The beer has an ABV of 5.76%, an apparent attenuation of 80%, and contains approximately 165 calories per 12oz serving. It is classified as a Standard style beer.

Convert 12.5 Plato to Specific Gravity.

12.5 Plato is approximately 1.051 Specific Gravity.

Is it possible to have an OG of 1.050 and an FG of 1.055?

No, that fermentation is not physically possible as the final gravity cannot be higher than the original gravity.

You can use either Specific Gravity (e.g., 1.050) or Plato (e.g., 12.5). The `calculate_abv_metrics` tool handles both automatically.
