开瓶时间长的红酒还能喝吗？打开时间久的红酒还能喝吗

开瓶时间长的红酒还能喝吗实这个问题很好回答，因为葡萄酒的保质期一般在3年左右，所以3年之后的红酒基本上已经失去了原有的风味，口感也大不如前。如果是在夏天喝，可能还会觉得有一点凉，但是到了冬天，就不一样了。

一：开瓶时间长的红酒还能喝吗有毒吗

因为怕葡萄酒失去最佳风味，很多人打开葡萄酒后都是一次喝完，但是如果实在喝不完，也不必勉强，事实上葡萄酒开盖后的保质期没有你想象的那么短。

There are many stuffy rules about wine, from the type of container it should come in to how expensive it should be. One common myth is that a bottle of wine should be fully consumed the same day it's opened. While it's true that vino does start to oxidize the moment the cork comes out, that's no reason to guzzle a liter of it all by yourself, or pour your leftover liquid down the drain. According toBon Appétit, an open bottle of wine is still good for several days—as long as you know how to store it properly.

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。

If you pop open a new bottle of cabernet just to have a glass or two, hold onto the cork. Corks have been an important part of the wine-making process for centuries. The material is dense enough to keep liquids fresh without sealing off air altogether. A minimal amount of oxygen allows the flavors of the wine to continue to develop, while too much oxygen creates an acrid, unpleasant taste.

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。

Once you've finished pouring your wine, squeeze the cork back into the bottle to prevent any more oxygen from reaching the drink. If you've damaged or accidentally tossed out your cork, a bit of plastic wrap with a rubber band, aluminum foil, or a reusable wine bottle stopper will work, too.

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。

Storing your opened wine in the fridge limits its exposure to other damaging elements like heat and light. Once it's refrigerated, most red and white wines will last two to five days before their flavors take a turn for the worse. Sparkling wines, however, have about one to three days before they're no longer drinkable, and some natural wines can go bad in a day. The highly tannic red wines available at the supermarket generally last the longest after being opened, with a lifespan of up to seven days.

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。

Because expiration dates vary so greatly between wine varieties, the best way to judge the freshness of what's in your bottle is to give it a taste. Overly oxidized wine doesn't taste great, but drinking a test sip of it won't make you sick. If you'd rather avoid drinking potentially spoiled wine, you can also judge its quality by sight and smell. Wine that's developed a brown tint and/or a vinegary smell has oxidized, meaning it's time to toss it and open a fresh bottle.

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。

二：开瓶时间长的红酒还能喝吗知乎

不能喝

开了很久的红酒最好不要喝了。红酒打开后，空气会进入瓶中，与酒液发生养化反应，一般在一周之后，酒液就会开始醋化，慢慢变酸，红酒口感变差，不适合饮用

开瓶过后的红酒一段时间之后口感就会变得很差，其原因主要是因为葡萄酒中含有酚类物质，打开瓶塞接触到了氧气就会发生氧化导致变质。这样不管是可口度，还是营养方面都得不到保证。

葡萄酒打开后3天，一旦葡萄酒被打开，空气中的氧气开始发生作用了，最初软化味道，打开葡萄酒的香味。由于这一氧化过程持续了许多小时和几天，葡萄酒最终无法饮用。所以应该在葡萄酒变质前喝完。为了减缓葡萄酒的氧化作用，可以把葡萄酒放冰箱里，冷藏保存，可以减缓葡萄酒的氧化过程，但是最好也不要超过一周，葡萄酒风味会随着时间慢慢消散直到变质。

三：开瓶时间长的红酒喝了会怎么样

1、红酒开瓶后一年喝了会比较容易导致胃肠道不适，出现腹胀、腹泻等症状，一般不会导致中毒。开过的红酒会和空气中的氧气发生化学变化，时间长了的话红酒会霉变。

2、红酒开了一年了就不能再喝了。红酒开瓶后只能保存3到7天，超过这个期限之后，红酒的风味和口感就会消失，变得平淡无味，酒质也会发生改变，变得不在适宜饮用了。
