A variety of factors and processes depend on pH including microbial stability, sulfur dioxide effectiveness, malolactic fermentation performance, protein stability, and sensory attributes.\u003c\/p\u003e\n\u003cp\u003eA wines microbial and chemical stability is influenced by pH due to the influence it has on the various forms of sulfur dioxide that will be present. Sulfur dioxide is responsible for protecting wine against oxidation and microbial activity. The molecular form of sulfur dioxide is most effective against microbes and is predominate at lower pH values. As the winemaking process progresses pH levels can change due to acid conversion and other metabolic activity. These changes require frequent monitoring of the pH values and sulfur dioxide levels of wine being stored or aged.\u003c\/p\u003e\n\u003cp\u003eMost wines have a pH value between 3.0 and 4.0. White wines tend to have pH values between pH 3.0 and 3.3, while higher pH values between 3.3 and 3.5 are more common for reds. Red wines sometimes have a higher pH, in part, due to the longer contact time the grape juice has with the grape skins. Early in the winemaking process and sometimes at points throughout, it may be necessary to make acid additions in order to set and maintain an optimum pH range for the desired style or condition of the wine. The pH of finished wine may also affect its color. For example, pigment compounds in the wine express different hues of color depending on the pH.\u003c\/p\u003e\n\u003ch4\u003eOn-Screen Features\u003c\/h4\u003e\n\u003ch5\u003eBacklit Graphic LCD Display\u003c\/h5\u003e\n\u003cp\u003eThese meters feature a backlit graphic LCD with on-screen help.
