Wine SO2 Equilibrium Calculator

Wine SO2 Equilibrium Calculator MCP Connector for Claude

A+

Calculate SO2 speciation and microbial stability in wine.

4 tools Official Updated Oct 1, 2026 Official Vinkius Partner

This MCP server provides winemakers with precise tools to manage sulfur dioxide (SO2) levels. By analyzing pH, alcohol, and temperature, it calculates the distribution of SO2 species, specifically identifying the molecular SO2 available for antimicrobial protection. Use get_current_speciation to see the current breakdown of free and bound SO2, calculate_required_addition to determine how much more SO2 is needed to reach a target molecular level, and evaluate_stability_risk to assess microbial spoilage risks.

What is the current SO2 speciation for a wine with pH 3.5, 13% alcohol, 20°C, and 40 mg/L total SO2?

The current speciation is: Free SO2: 25.4 mg/L, Molecular SO2: 4.2 mg/L, Bound SO2: 14.6 mg/L, Total SO2: 40.0 mg/L.

How much SO2 should I add to reach 0.8 mg/L molecular SO2 if my current pH is 3.6, alcohol is 12%, temperature is 18°C, and total SO2 is 30 mg/L?

To reach a target of 0.8 mg/L molecular SO2, you need to add 12.5 mg/L of total SO2.

Is my wine stable with pH 3.8, 14% alcohol, 22°C, and 35 mg/L total SO2?

The current molecular SO2 is 0.5 mg/L, which is below the 0.8 mg/L threshold. The risk level is Moderate.

It determines the current distribution of SO2 species, including free, molecular, and bound SO2, based on the wine's pH, alcohol, and temperature.
