酒酸了

　　酒酸了是什么原因？

　　酒酸了的原因是葡萄酒被过度氧化了，葡萄酒在没有密封的情况下放置的时间过长，酒液与空气中的氧气一直在发生氧化反应，渐渐的酒变成了葡萄酒醋，所以口感会变酸。

　　酒酸了是什么原因？

　　葡萄酒变酸，多半是因为葡萄酒过度氧化了，就像葡萄酒如果醒酒过度，葡萄酒也会慢慢变酸是一样的。

　　葡萄酒也会像金属一样，在氧气过多时易被氧化。氧化是葡萄酒常见的缺陷，葡萄酒氧化常见的原因是存储不当。被氧化的葡萄酒在颜色和风味上都失去了其原有的特色，其颜色由原来的亮红变成砖红或棕红，缺少光泽，而其口感也由新鲜变得干涩偏酸。白葡萄酒比红葡萄酒更容易氧化，这是因为红葡萄酒中的高单宁可以减缓氧化的速度。

　　闻闻葡萄酒中是否有氧化的迹象，当空气进入一瓶葡萄酒中时会发生氧化作用。未妥善储存的开封葡萄酒很容易被氧化，会发出刺鼻的气味，就像醋一样。这种气味很容易辨认。

　　What reason is wine sour？ The reason why the wine is sour is that the wine has been over-oxidized. The wine has been left unsealed for too long. The wine has been oxidizing with the oxygen in the air. Gradually， the wine becomes wine vinegar， so the taste will turn sour. What reason is wine sour？ Wine Sour, mostly because of excessive oxidation of wine, just like if wine decanter excessive, wine will slowly sour is the same. Like metals, wine is prone to oxidation when there is too much oxygen. Oxidation is a common defect in wine. The common cause of wine oxidation is improper storage. Oxidized wine loses its original characteristics in color and flavor, its color from bright red to brick red or brown red, lack of luster, and its taste from fresh to dry acid. White wine oxidizes more easily than red wine, because the high tannins in red wine can slow down the rate of oxidation. Smell the wine for signs of oxidation, which occurs when air enters a bottle of wine. Improperly stored Kaifeng wines are prone to oxidation and give off a pungent smell, like vinegar. The smell is easy to identify.
