Red Wine

紅葡萄酒是一種由深色(黑色)葡萄品種製成的葡萄酒。 葡萄酒的實際顏色可以從濃烈的紫羅蘭,典型的年輕葡萄酒到磚紅色的成熟葡萄酒和棕色的老紅葡萄酒。 大多數紫葡萄的汁液呈綠白色, 紅色來自葡萄皮中存在的花青素(也稱為花青素) 例外是相對罕見的teinturier品種,這產生了一個富含紅色的果汁顏色。 葡萄酒生產過程因此涉及從葡萄皮中提取顏色和風味成分。

Red wine is a type of wine made from dark-coloured (black) grape varieties. The actual colour of the wine can range from intense violet, typical of young wines, through to brick red for mature wines and brown for older red wines. The juice from most purple grapes is greenish-white; the red colour comes from anthocyan pigments (also called anthocyanins) present in the skin of the grape; exceptions are the relatively uncommon teinturier varieties, which produce a red coloured juice Much of the red-. wine production process therefore involves extraction of colour and flavour components from the grape skin.
