The important of pH in Wine making

         The pH of wine is important to determine because it will affect the quality of the final product in term of taste, color, oxidation, chemical stability  and other factors. Generally in winemaking, the higher the pH reading, the lower amount of acidity in the wine. Three important factors in determining  the pH of wine include the ratio of malic acid to tartaric acid, the amount of potassium, and the total amount of acid present.


          Most wines optimally have a pH between two point nine and four, with values differing based on the type of wine. Value above pH 4.0 indicate that the wine may spoil quickly and be chemically unstable. Lower pH values allow the wine to stay fresher for a longer period and retain its original color and flavor. High pH wine is more likely to breed bacteria and become unsuitable to drink. For finished white wine, the ideal pH is between pH 3.00 and pH 3.30, while the final pH for rea wine is ideally between pH 3.40 and pH 3.50. The optimal pH before the fermentation process is between pH 2.9 and pH 4.0. The pH of wine therefore not only affects the color of wine, but also the oxidation, yeast fermentation, protein stability and bacteria growth and fermentation.

  HI98128 pHep Waterproof pH meter with Replaceable Electrode

  • Dual Level Display Showing pH & Temperature
  • 0.01 pH resolution.
  • Percent Remaining Battery Indicator.
  • Replaceable pH Electrode.
  • Rugged, Floating Waterproof Casing.








Replaceable pH electrode : Electrode replacement with the stainless steel round connector means there are no pins to bend or break during replacement

Cloth extendable junction : When the cloth junction becomes dirty from routine testing, simply pull out 3 millimetre(1/8 inches) to increase response time and stability.

Exposed temperature sensor : The exposed temperature sensor provides fast response time, and its proximity to the pH electrode guarantees greater accuracy in temperature compensated readings.
