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.
