Oxidation is a chemical reaction that occurs when oxygen in the air comes in contact with the alcohol in wine, converting ethanol into acetaldehyde, then acetic acid. It causes wines to lose their vibrant colors: white wines become brown, red wines develop orange hues. It also reduces fresh fruit aromas and introduces nutty or vinegar notes. Although it is harmful in excess, controlled oxidation is beneficial while aging wine.<\/p>\n","protected":false},"author":4,"featured_media":0,"template":"","glossary_category":[113],"class_list":["post-13934","wcp_glossary","type-wcp_glossary","status-publish","hentry"],"yoast_head":"\nWine
