Malic acid (C\u2084H\u2086O\u2085) refers to a naturally occurring organic acid in wine grapes, primarily found in unripe grapes or cool climate berries. It gives wines a sharp, green apple like acidity, tartness and freshness. It is very important in crisp white wines like Sauvignon Blanc and Riesling, but winemakers convert it to softer lactic acids in red wines during the process of malolactic fermentation. Sometimes, producers add malic acid powder to boost acidity in overripe grapes.<\/p>\n","protected":false},"author":4,"featured_media":0,"template":"","glossary_category":[113],"class_list":["post-13901","wcp_glossary","type-wcp_glossary","status-publish","hentry"],"yoast_head":"\nMalic Acid Meaning: Wine Terms Explained -
