開瓶後的葡萄酒可以飲用多久How Long is Wine Drinkable After Opening
這個問題沒有一個確定的答案， 即使在打開一天之後，葡萄酒總會有一些降解，儘管起初它不會明顯被檢測到， 大多數葡萄酒在打開幾天后都可以很好地飲用，只要瓶頸以某種方式塞住，以進一步阻止空氣進入。
具有諷刺意味的是，一瓶已經發酵多年的葡萄酒在開瓶後幾天內都會變壞，但即便是葡萄酒也有局限性，葡萄酒變質的原因在於，在發酵過程中葡萄酒的味道更好 ，氧化，由於葡萄酒暴露在氧氣中，這在打開後是不可避免的，隨著時間的推移它開始變質。
如果你想讓你的葡萄酒持續更長時間，有許多配件可以幫助你盡可能長時間保持新鮮，專業的瓶塞可以起到不同程度的效果，但是一旦瓶子被打開，它們都不能完全阻止葡萄酒的降解，保持葡萄酒冷藏也有幫助，因為低溫會減緩化學變化，保持葡萄酒不受光照也是個好主意。
不同類型葡萄酒的保質期
以下是葡萄酒開封後的長壽指南， 這是假設瓶子被正確“塞住”並存放在冰箱中。
Red Wines
如果你是那種喜歡慢慢品嚐葡萄酒的人，那麼紅葡萄酒絕對適合你，只要密封和冷藏，大多數紅色瓶子在打開後最多可以飲用5天。
打開瓶子後，構成紅酒結構和身體的酸和單寧將開始分解，有時這不是一件壞事，許多更為澀的紅葡萄酒，例如年輕，濃郁的紅葡萄酒，在它們被打開後的第二天可能會更加美味，你會注意到更嚴厲的音符會減少，而較軟的結構會讓紅葡萄酒更加微妙。
然而像勃艮第和其他黑比諾或桑嬌維塞葡萄酒一樣，較為濃郁的紅葡萄酒，其結構將比大而大膽的赤霞珠和西拉葡萄酒更快地失去其結構，因此這些較淺的紅葡萄酒應該在2-3天內飲用，因為它們會更快地變平。
Rosé & Lighter White Wines
當我們想要一些清淡，新鮮和夏季的東西時，我們可以買到我們最喜歡的白葡萄酒和桃紅葡萄酒，這些葡萄酒的重點是提供有彈性和酸性的東西，充滿生機，帶有尖銳的水果和礦物質元素。
因此冷凍較淡的白葡萄酒，和大多數桃紅葡萄酒將是最令人滿意的新鮮開瓶，然而這並不意味著一旦你有足夠的東西就需要拋棄任何多餘的東西。
憑藉精心製作的高品質葡萄酒瓶，即使是輕甜的玫瑰紅葡萄酒和白葡萄酒，在5-7天的冰箱中也絕對精美，這意味著它們可以在長周末享用。
在前3天左右，他們的性格將開始改變，你會發現舌頭上的初始“新鮮感”可能會有所減少，但這可能不是一件壞事， 這些葡萄酒肯定仍然可以飲用。
Full-Bodied White Wines
濃郁，濃郁的白葡萄酒比較輕的“堂兄弟”靈活性差。
霞多麗、維歐尼、特雷比亞諾、白里奧哈….. 以其豐富和豐滿而著稱和喜愛 在老化過程中，在被釋放之前已經經歷了相當多的氧氣。
因此這些白葡萄酒將比開放後更年輕，更新鮮的例子更快地消亡。
這些種類的葡萄酒最好在開封後3天內完成，因為它們在較長時間後會變得非常難以飲用。
Sparkling Wine & Champagne
我們都經歷過忘記一瓶開口的蘇打水，然後回到它身上，卻發現了一種平坦，令人不愉快的脫碳液體。
同樣的事情很容易發生在起泡酒上，很快就會失去頭暈， 36小時後這些起泡酒不應該被吸收 – 這些葡萄酒從它們的細小氣泡中獲得它們的特徵，喝“死”的香檳永遠不會有多麼有趣也不令人滿意。
Prosecco和Asti也應在開業後2天內食用。
Fortified Wines
Shelf Life = 4 to 5 weeks
像Port和雪利酒這樣的強化葡萄酒與以前的葡萄酒不同，因為它們具有更高的酒精含量，被葡萄酒“強化”，並且它們的含糖量也更高。
這兩個因素都意味著開瓶港的保質期將比任何餐桌或起泡酒長得多，但是，這個時期並不是無限期的。
實際上4-5周是您可以預期保留一瓶強化葡萄酒的最長時間，一旦它開始降解並且失去所有那些深層，複雜，風味和特徵之後它就被打開了。
如果你想讓它們持久，你可以將它們放在涼爽，黑暗的地方，就像其他任何好酒一樣。
所以你有它 – 快速指導這些瓶裝各種葡萄酒在打開後會持續多久，請記住這些提示：給自己一個好的，可靠的瓶塞，並使用你的冰箱！然後你再也不會感到難過，因為你看著自己喜歡的葡萄酒，倒在排水溝裡。
How Long Does a Bottle of Wine Remain Drinkable After Opening?
There isn’t one definitive answer to this question. There will always be some degradation of the wine, even after one day of being opened – although it won’t be obviously detectable at first. Most wines are absolutely fine to drink after a couple of days of being opened, so long as the bottle neck is stoppered in some way which stops further air coming in.
It’s ironic to think that a bottle of wine that has been fermenting for a number of years can go bad within days of opening, but even wine has limitations. The reason wine goes bad is from the same thing that makes wine taste better during the fermentation process – oxidation. As wine is exposed to oxygen, which is unavoidable after opening, it begins to spoil over time.
If you want to make your wines last longer, there are many accessories that can help you keep it fresh for as long as possible. Professional bottle stoppers will work with varying degrees of effectiveness, but none of them will completely halt the degradation of the wine once the bottle has been opened. Keeping your wine refrigerated helps too, as low temperatures will slow chemical changes, and keeping your wine out of light is also a good idea.
The Shelf Life of Different Types of Wine
Here are some guidelines for the longevity of wine after it has been opened. This assumes that the bottles are properly “stoppered” and stored in a refrigerator.
Red Wines
- Shelf Life = 3 to 5 days
If you are the kind of person who likes to savor their wines slowly, then red wines are definitely the ones for you. The majority of bottles of red will be absolutely fine to drink up to 5 days after they’re opened, so long as they are sealed and refrigerated.
After a bottle is opened, the acids and tannins that make up the structure and body of red wine will start to break down. Sometimes this isn’t a bad thing. Many of the more astringent bottles of red wine, for example young, full-bodied reds, will probably be a lot more palatable the day after they’ve been uncorked. You’ll notice the harsher notes will have been diminished, and the softer structure will allow more subtleties of the red wine to come forward.
Lighter bodied reds, however, such as Burgundy and other Pinot Noir or Sangiovese-based wines, are going to lose their structure far more quickly than the big, bold Cabernet Sauvignon and Shiraz wines. Therefore, these lighter red wines should be drunk within 2-3 days, because they will go flat more rapidly.
Rosé & Lighter White Wines
- Shelf Life = 5 to 7 days
When we want something light, zesty, fresh and summer-like, we reach for our favorite white and rosé wines. The whole point of these wines is to offer something springy and acidic, full of life, with sharp fruit and mineral notes.
As such, chilled, lighter white wines and most rosé wines are going to be most satisfying poured from a freshly-opened bottle. This doesn’t mean, however, that any excess needs to be thrown away once you’ve had enough.
With a well-made, high-quality wine stopper, even light rosé wines and white wines will be absolutely fine in the fridge from 5-7 days, meaning that they can be enjoyed over a long weekend.
After the first 3 days or so, their character will begin to change. You’ll find that the initial “freshness” on the tongue may be lessened somewhat, but this again might not be a bad thing. These wines will certainly will still be drinkable.
Full-Bodied White Wines
- Shelf Life = 2 to 3 days
Full bodied, stronger white wines are less flexible than their lighter “cousins”.
Chardonnay, Viognier, Trebbiano, White Rioja and others — celebrated and loved for their richness and fullness — already undergo a fair amount of oxygen during the aging process, before being released.
Because of this, these white wines will perish rather more quickly than younger, fresher examples after opening.
These sorts of wines are best finished within 3 days of opening, as they tend to become really rather unpleasant to drink after a longer period.
Sparkling Wine & Champagne
- Shelf Life = 36 hours
We’ve all experienced forgetting an open can of soda, and returning to it, only to find a flat, unpleasant, de-carbonated liquid in its place.
The same thing can easily happen to sparkling wine, which lose fizziness quite quickly. After 36 hours, these sparkling wines shouldn’t be imbibed – these wines get their character from their fine bubbles. To drink a “dead” Champagne is never going to be much fun nor satisfying.
Prosecco and Asti also should be consumed within 2 days of opening, as well.
Fortified Wines
- Shelf Life = 4 to 5 weeks
Fortified wines, like Port and Sherry, are the different than the previous wines, because they have a higher alcohol content, being ‘fortified’ with grape spirits, and they have a higher sugar content, too.
Both of these factors mean the shelf life of an opened bottle of Port will be much longer than any table or sparkling wine. However, this period is not indefinite.
Realistically, 4 – 5 weeks is the maximum amount of time you can expect to keep a bottle of fortified wine, once it has been opened before it begins to degrade and lose all those deep, complex, flavors and features.
Keep them in a cool, dark place, as you would any other good wine, if you want to make them last.
So, there you have it – a quick guide to how long those bottles of various wines are going to last after they’ve been opened. Please keep these tips in mind: Get yourself a good, trusty bottle stopper, and use your refrigerator! Then you’ll never have to feel sad again, as you watch your favorite wine, being poured down the drain.
