葡萄酒开盖后能保存多久？

从装酒的容器到酒的价格，关于葡萄酒有很多老讲究。一个常见的误解是一瓶葡萄酒必须在开盖的当天喝完。尽管一开盖酒就会开始氧化，但是没有必要因此独自干掉一整瓶，或者将剩余的葡萄酒倒进下水道。据美食杂志《好胃口》称，只要储存方法得当，葡萄酒开盖后可以保鲜好几天。

如果你打开一瓶新的赤霞珠红葡萄酒只是为了喝上一两杯，那么不要丢掉木塞。几个世纪以来，木塞一直是红酒酿造流程的一个重要部分。木塞材质的密度足以在不完全隔绝空气的情况下保持酒的新鲜。瓶中有少量氧气可以让葡萄酒继续发酵，而氧气过多则会导致葡萄酒变得酸涩，口感不佳。

一旦你倒完酒，就要立即用木塞密封酒瓶，防止更多氧气进入瓶中酒。如果你损坏或不小心扔掉了木塞，你可以用橡皮筋和铝箔包住一团保鲜膜作为瓶塞，或者用可重复使用的酒瓶塞。

将开盖后的葡萄酒放在冰箱里，可以减少葡萄酒接触热和光等其他会导致葡萄酒变质的因素。只要放在冰箱中，大多数红葡萄酒和白葡萄酒都可以保持2到5天不变味。不过，起泡葡萄酒开盖后只有1到3天的保质期，有些天然起泡葡萄酒开盖后一天就变质了。超市卖的高单宁红葡萄酒通常开盖后保质期是最长的，最多可以保鲜7天。

由于不同的葡萄酒品种保质期差别很大，判断葡萄酒是否新鲜的最佳方式就是尝一尝。过度氧化的葡萄酒口感不佳，但是试喝一口不会让你生病。如果你实在不想喝可能变质的葡萄酒，你也可以通过外观和气味来判断它的品质。颜色转为褐色或散发出酸味的葡萄酒已经氧化了，这说明你该把它扔掉，再开一瓶新酒了。
