Lower pH values are known to improve stability, so winemakers usually prefer a pH range of 3.0 to 3.5.<\/p>\n<p>Wine pH depends on:<\/p>\n<ul>\n<li>Total amount of acid present<\/li>\n<li>Ratio of malic acid to tartaric acid<\/li>\n<li>Amount of potassium present<\/li>\n<\/ul>\n<p><strong>High ph Wine Values<\/strong><\/p>\n<p>Wines containing little acid and excessive potassium reveal high pH values. With high pH values in wine, bacteria grow rapidly and undesirable bacterial fermentation becomes more of an issue. This creates less biological and chemical stability. The color is also poor. Wines with a high pH need more attention.<\/p>\n<p><strong>Low pH Wine Values<\/strong><\/p>\n<p>When wine has lower pH values, it has more tartaric acid but less malic acid and less potassium. Low pH inhibits bacteria and causes sugar fermentation to progress more evenly. It also makes malolactic fermentation easier to control.<\/p>\n<p>Low wine pH offers better visual qualities as well\u2014both red and white wines have richer color intensity. Red wines contain more color and white wines do not brown as easily.<\/p>\n<p><strong>Measuring pH<\/strong><\/p>\n<p>To measure pH levels in wine, use a <a href=\"https:\/\/www.coleparmer.com\/Category\/pH_Meters_Ion_Meters_and_ISFET_Meters\/3415\" target=\"_blank\" rel=\"nofollow noopener noreferrer\">pH meter<\/a> with up to 3-point pH calibration or a handheld meter with 5-point pH calibration for accuracy and reliability.<\/p>\n<p><em>View our selection of <\/em><a href=\"https:\/\/www.coleparmer.com\/Category\/pH_Meters_Ion_Meters_and_ISFET_Meters\/3415?referred_id=5618\" target=\"_blank\" rel=\"nofollow noopener noreferrer\"><em>ph meters<\/em><\/a><em>.<\/em><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Wine\u2019s chemical and biological stability depend on pH value. pH values range from 2.9 to 4.2 in wine, as measured by pH meters.
