PSA：这里是如何判断你冰箱里的葡萄酒仍然好

Contrary to popular belief, not all wines improve with age. The vintage bottles coveted by collectors were specifically made to mature over long periods of time. Most wines — even the ones you might buy for an extra-special occasion — should only be stored for a year or two, after which they run the risk of going bad. It’s also possible for a bottle of wine to pass its prime well before its expiration date, which is a devastating realization to make whenyou’re pouring yourself a glassafter a long, hard day.如果你质疑你的葡萄酒is still worth drinking，这是如何检查它的。

葡萄酒如何变坏？

Once a bottle of wine has been opened, it’s on its way to going bad. Uncorking a bottle exposes the wine to air, which slowly oxidizes it. Over time, the air begins to convert acetaldehyde — a volatile compound found in all wines — into acetic acid, gradually turning that wine into vinegar. This is why it’s important that an open bottle of wine be sealed tightly if it’s not going to be fully consumed in a single sitting, ideally using a device that can remove the oxygen from its bottle or whatever container you choose to store it in.

Once sealed tightly,储存葡萄酒在冰箱里;冷温度会减慢氧化过程，但不会阻止它。制冷葡萄酒可能会额外一两天给你的瓶子，但不得多。

未开封的葡萄酒也可以变坏，如果你在舒适的家中建造一系列年龄的年龄，那么他们必须正确存放，所以当你终于弹出那个软木塞时，你的心脏不会被打破。储存瓶子在两侧，使软木塞始终与葡萄酒本身接触，这将防止它们干燥。干软木塞将少量空气渗入，这将在储存中萎缩时慢慢氧化葡萄酒。

There are three simple steps to being able to tell if your wine is ready to drink, first by sight, then by smell, and finally by taste. Here's what you need to know.

What Does the Wine Look Like?

在一瓶酒中检查的第一件事是软木塞;如果它看起来像是不合适的 - 特别是如果它被推出了一点 - 有可能在产生过量气体的瓶子内发生化学反应，使软木带来压力的瓶子。它也可能意味着在某些时候，葡萄酒过热了很多时间，如果你经过高中化学，你可能会记得热量扩张。

接下来，将一些葡萄酒倒入玻璃杯中并检查它。如果你注意到任何破碎的软木塞，奇怪的云，或者看起来被任何异物被污染，扔掉，永远不会回头看。寻找微小的气泡 - 如果你的葡萄酒很闪闪发光but you didn’t buya sparkling wine, it means your wine has undergone a secondary fermentation. If you want to drink your double fermented wine it’s perfectly safe, but you’ll more than likely be disappointed by the strongly sour flavor it has developed.

Hold the wine up to a light and examine its colors. Is the wine vivid, crisp and colorful like a wine should be? Or is it dull, cloudy, or discolored? When wine goes bad it slowly discolors, fading and taking on a yellowish-brownish tint.

How Does the Wine Smell?

一个糟糕的气味是一个简而言之的方式来知道你的葡萄酒是坏的 - 记住，你的嗅觉与你的味觉有关，所以如果你发现一个葡萄酒的味道完全令人厌恶，它会味道不好，或者更差。然而，宠坏的葡萄酒并不总是发出强烈令人反感的气味，因此您需要在守望方面进行Telltale Notes。通过旋转玻璃并嗅到花束，寻找霉味，发霉的气味;一些比较这种闻到潮湿的地下室或湿狗。If you smell vinegar or rotten eggs, it means your wine is now ripe with sulphur, and should be poured straight down the drain.

它什么味？

If examination by sight and smell doesn’t raise any glaring red flags, you’ll need to make your final decision by actually tasting the wine. There are a few things to look for that will indicate that your wine is bad. If you’re drinking red wine, it shouldn’t be overly sweet (Unless it’s a Port or dessert wine) As mentioned earlier, if a non-sparkling wine is sparkling, something’s off. If there’s a sharp taste akin to vinegar, the wine is no-good. And if it doesn’t taste like something you would actually enjoy drinking, you shouldn’t.十分简单。
