The acidity of wines has been decreasing steadily for more than 20 years due to climate change, thus altering their sensory profile and color.

Increasing the acidity has become a major challenge for oenologists.

STARSpH is an innovative, continuous, single pass, additive-free technology that extracts excess potassium (acidification) or excess tartaric acid (de-acidification), thus restoring the natural acidity of the treated must or wine. The process is based on bipolar-membrane Electrodialysis technology, is easy to use at any time during vinification and enables the pH of wine and musts to be adjusted naturally and with precision.

STARSpH can process your wine continually without altering its organoleptic potential and delivers a wine that is protected from oxidation, without any bitterness, and that is fresh in the mouth.

It has no effect on the final product other than controlling its acidity and consequently delivering a natural improvement of its quality. It achieves an easily adjustable pH reduction of 0.1 to 0.5.
