Adjust pH Naturally and Precisely with Oenodia STARS® Technology Traditional pH adjustment tools like tartaric acid and potassium carbonate often lack precision and can alter wine flavor, especially after fermentation. Oenodia’s STARS electrodialysis process is a smarter way to fine-tune pH, enhancing flavor, color, and SO₂ performance. Why Adjust Acidity? Stability: Enhance SO₂ Effectiveness Sulfur dioxide is most effective within a specific pH range to protect wine from microbial contamination and oxidation. When pH>3.65, its effectiveness drops, requiring higher free SO₂ levels. Lowering pH helps maintain wine stability with less intervention. Sensory Adjust Flavor and Color pH plays a key role in a wine’s sensory profile and visual appeal. A lower pH can sharpen flavor balance, reduce flabbiness, and enhance freshness. pH also influences color, especially in reds and rosés. pH adjustment is a natural way to shift color.
