In , an article in the Journal of Agricultural Chemistry found evidence that ethanol evaporates once a wine has been poured into the glass, slightly lowering the abv content. It said this was strongly influenced by exposure to air. He said that decanting accelerates the breathing process by encouraging volatile aromas to evaporate and emphasising fruit and oak aromas.
Others have argued that advances in winemaking mean that fewer wines require the sort of aeration that might have been considered beneficial in the past. However, some producers prefer to double decant younger wines , too, and particularly those that have high tannin levels. Be careful with older vintages, which can be much more sensitive once opened and may lose fruit aromas much more quickly. Perhaps the best thing to do is conduct your own research, which may necessarily involve opening a bottle or two.
Once I tried a six-year-old Sauvignon Blanc with trepidation. I put it back in the fridge and noted that it was still unpleasant when I used it to cook with about a week later. Another few weeks passed, and I ended up drinking the remaining three-quarters of the bottle with a friend.
It was glorious! My point is that you simply don't know how an opened bottle of red or white wine is evolving until you try it. After all, wine is a living product.
It literally breathes, just like we do. Keeping open wine fresh means reducing the wine's oxygen exposure and slowing down the wine's oxidation reactions. So, let's explore how to preserve open wine. There are all sorts of tools for preserving open wine at just as many price points. But if you have the right wine preservation technique for your open bottle of white wine - screwcapped or not, you may not need anything else.
Moreover, the same principles apply for storing open red wine. Keep in mind that the greater the volume of wine left in the bottle, the better it will keep.
Also, the more times you open the bottle, the shorter the life of the wine will be. First, recork wine the way a winemaker would. That is, place the end that was in the bottle back into the bottle. Corks expand when they are pulled out, making it easier to put the end previously facing you back into the bottle first.
However, you'll never catch a winemaker doing that. They worry that the outward-facing side could spoil the wine if, say, that side was slightly cork taint affected but the side that had been facing the wine wasn't. Besides, it just seems more sanitary.
The top of the cork has been exposed to lots of things on its journey from the winery. If your wine is closed with a screwcap or a glass cork, this first step is even easier. The opposite is true with those inflexible, plastic-y feeling ones. There's no amount of muscle and there's no secret angle that will convince those corks to squeeze back into a wine bottle neck.
So, it's useful to keep an extra cork or three around, all in slightly different widths as wine bottle necks aren't all the same size. If you're a clutterphobe, you can always give the extra corks a second shift, standing in as safety coverings for the end of an ice pick or a cooking thermometer shoved into a drawer! That way you always have a spare cork on hand, but it's serving a functional purpose in the meantime.
This is also helpful for those times you plan to drink a bottle and toss the cork but then don't finish it after all. Sometimes glass stoppers from wine bottles are worth keeping around, too.
They often fit best into smaller-necked bottles. As a last resort, just cover the opening with plastic wrap and snap on a rubber band. If you know you're not going to finish a bottle, don't let it sit un-stoppered on your counter or in your fridge. Pop the screwcap back on or shove the cork in as soon as you've poured your glass. Similarly, if you're not finishing a bottle of wine in one go, don't decant it. Let the wine breathe in the glass es instead.
If you really need to "decant" or oxygenate a single glass, pour the single serving back and forth into a second wine glass to achieve your desired level of aeration. Does wine need to be refrigerated after opening? It's basically all pros and almost no cons when it comes to refrigerating open wine. Cold temperatures significantly delay oxidation reactions, but the open wine bottles will still be changing in your refrigerator.
Just as you store open white wine in the refrigerator, you should refrigerate red wine after opening. Beware that more subtle red wines, like Pinot Noir, can start turning "flat" or taste less fruit-driven after a few days in the refrigerator.
Still, how long red wine lasts after opening will improve if you opt for the refrigerator rather than the counter. Balking at the idea of cold red wine? Taking red wine out of the fridge half an hour before you drink it will do the trick. If you're too thirsty to wait, run lukewarm water over the bottom of the bottle while turning it for even heat distribution.
If you're really desperate, you can even pour a glass then carefully rotate the exterior of the glass under the faucet. If you think the idea of refrigerating red wine is just too bonkers, at least try to store the wine in a cool, dark place or away from lights that give off heat. I generally place my opened red wines back in my wine fridge, where they lay horizontally. This keeps them at the right temperature while stored and has them ready for drinking when I am.
However, this is only a good idea for drinking already opened red wine the next day or two. This is because of the oxygen exposure principle. If a bottle is laid flat for storage, more wine surface will be exposed to air in the bottle.
If the bottle is stood on end, there is less air exposure. A great way to save half a bottle of wine is to pour it into a ml half bottle. To do this, bring in a decanter , a large pitcher or even a water jug. Rinse well traces of detergent are formidable. The temperature of the wine must be that of wine storage to avoid unwanted chemical reactions.
Pour the equivalent of a small glass into the carafe and then taste it: If the taste has improved, the wine claims oxygenation, pour the amount you intend to drink. If the structure has fled, leave the rest in the bottle. If the aromas are still weak and the structure is tight, the wine is said to be closed. Shake the carafe or transfer the wine several times, it might soften as much. What is the ideal temperature for a wine Wine tastes better at a moderate temperature. It is convenient to serve wine slightly cold rather than warm as the wine warms up in the glass.
In the summer, serving wine fresh means going through the refrigerator. How to reach and keep wine at ideal temperature So how to quickly cool a bottle of wine? Here I am proposing three easy methods, from the simplest to the most risky Put the wine bottle in a bucket of water with much ice. The water melts the ice quickly and the bottle is surrounded by chilly water.
