Conductivity (Tartrate Stability)

Application Importance of Measuring Conductivity (Tartrate Stability) in Wine

Tartaric acid and its various forms are naturally found in grapes and wine. The principal form of tartaric acid present in wine is potassium bitartrate, commonly abbreviated as KHT. As grapes develop on the vine, potassium from the soil moves into the ripening fruit and forms soluble KHT. The presence of KHT in wine can lead to its precipitation, or formation of crystalline deposits, in a finished product. KHT crystals are the visible particles that may appear at the bottom of wine bottles during storage, export, or when chilled before consumption. While natural and harmless, it can be perceived as undesirable for a customer.

Tartrate stability can be determined through the use of a conductivity meter. When KHT crystallizes during cold stabilization, there is a loss of potassium ions as it forms a precipitate. The loss of potassium ions from solution results in a drop in conductivity. Higher drops in conductivity during the test indicate less stable wines.

Calibration Solutions

Conductivity Calibration Solution

Accurate conductivity (EC) and Total Dissolved Solids (TDS) measurements are only as good as the calibration standard used. EC/TDS standards are susceptible to change due to contamination. For calibration we offer a variety of packaging sizes based on your use.

  • All solutions sealed to prevent any air from entering the solution
  • Solutions are made by Hanna Instruments and are traceable to NIST standard.
  • Available in variety of sizes from single use 20 ml sachets to a 1 gallon bottle
