Research backgroundCopper (Cu) is a metal ion commonly found in all wines, with concentrations usually less than 0.5 mg\/L. Copper in wine may come from viticulture, including application of fungicides and absorption from the soil, or during wine production (including contamination and additions caused by winemakers). In fact, copper is often deliberately added to wine to suppress reducing odors, such as those caused by hydrogen sulfide, by forming non-volatile complexes with these adverse aroma compounds. Excess hydrogen sulfide can make the copper in wine form copper organic acid complex, this form of copper can ensure that the wine is not affected by the accumulation of hydrogen sulfide in the short term. For copper sulfide complexes left over from wine production, subsequent filtration (0.45\u03bcm or 0.20\u03bcm) often fails to remove them. Finally, excess copper in wine can cause copper fog, but this usually requires a much higher concentration of copper than\u2026<\/p>","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[3],"tags":[],"attr":[135],"class_list":["post-1963","post","type-post","status-publish","format-standard","hentry","category-problems"],"_links":{"self":[{"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/posts\/1963","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/comments?post=1963"}],"version-history":[{"count":1,"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/posts\/1963\/revisions"}],"predecessor-version":[{"id":1970,"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/posts\/1963\/revisions\/1970"}],"wp:attachment":[{"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/media?parent=1963"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/categories?post=1963"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/tags?post=1963"},{"taxonomy":"attr","embeddable":true,"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/attr?post=1963"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
