Molecule In Corked Wine Plugs Up Your Nose
sciencehabit writes "Ever send a bottle of wine back at a restaurant? If you weren't just being a pretentious snob, then it was probably because the wine seemed 'corked' — had a musty odor and didn't taste quite right. Most likely, the wine was contaminated with a molecule called 2,4,6-trichloroanisole (TCA), the main cause of cork taint. But a new study by Japanese researchers concludes that you do not smell TCA directly; rather, TCA blocks up your sense of smell and distorts your ability to detect odors. The findings could help the food and beverage industry improve its products and lead to less embarrassment for both you and your waiter."
Seriously, other than nostalgia why are they still using corks when much better methods have existed for decades?

Yeah, I'm not even a really big wine connoisseur, but I'd say the high priced wines have more to do with vintage than any other single factor. The idea that "The older, the better!" is only true in a very general sense and subject to so many exceptions and other mitigating factors, it's really not a good way to determine if a given bottle of wine will taste good to you.
At some point, I think it's more about showing off/snobbery, really.... That feeling of superiority one gets from cracking open a bottle that's sat, undisturbed, for so many years. People will pay for that experience.
surely it's the sommelier who will be embarrassed, not the waiter...

that giggled at the phrase "cork taint"? Please don't tell me I'm the only one.
If they are finding things that block smell, can I spray some of my coworkers with it?

Just wait until it's too expensive to drive around. There will be con men who will sell crude oil that has been 'naturally aged for millions of years' to clueless folks with more money than sense. They'll use it lightly to dress their salads and to flaver their roasted entrees.
This is my signature. There are many like it, but this one is mine.

When I send back wine, it's because it's turned to vinegar.
Sending back a corked bottle shouldn't embarrass anyone. It's fairly rare but does happen from time to time. The restaurant shouldn't even think twice about it.

The last paragraph gave me the following thought.
Given how much the food industry is "concerned" with providing us with the best quality,
is it potentially possible that they can use this molecule to block our ability to sense some bad stuff that is in their products?
Sorry, but wine does change taste once it's in the bottle and even more so before it is bottled. Beaujolais Primeur is a wine that is best very soon after it is made, it deteriorates rather fast and is ready for vinegar after a year or so. Other wines are the opposite, they require longer time in the cask and even longer time in the bottle to reach their best taste. The famous French Bordeaux region chateau wines are a good examples of this.
Wine price is a combination of rarity, popularity and taste. Once wines get "expensive" the price of production, packaging and storage isn't a major factor any more, but for most wine, it is. The prices you pay in fancy restaurants are often way more than the same wines would cost in trade or in a liquor store. I don't know about the USA, but in Europe, many restaurants only break even on the food and have to get their profits on the drinks you order while you are in the establishments. That means that if you and your dining partner are in the shop for an hour, your bottle of wine you share will basically have to get enough money out of you to pay for the wages of the people caring for you during your stay and the profit of the restaurant owner. Don't be surprised if there's a $30 or more markup on that single bottle...

The contamination covers a broad range and not everyone has the same sensitivity to it. That is why to some a wine may just not taste very good while to others it clearly has cork taint even if it still is drinkable. That is also a reason why estimates of the fraction of wines that's corked vary a lot, at least if they're based on experience. I'd put it at 5 to 10%, but then I'm sensitive to cork taint.
If you want to oxygenate the box wine before serving, just pour it into a carafe a little ahead of time. The wine remaining in the box stays as it is but the wine in the carafe gets the oxygen needed to take care of some of the tannins. Seriously, even with wine in a bottle, using a carafe is a good way to deal with tannins.
A nice carafe can also help show off the wine itself.

In fact, a box is one of the best ways to store and distribute wine.
True! I, too, buy most of my wine in boxes. Usually containing six bottles each. Very convenient!
Isn't this the wine project icon?
Nope, it is recyclable box containing a non-recyclable plastic bag which in turn contains the nectar of life.
I do not understand all this fuss about aroma and taste and TCA (trichloroacetic acid?). After all people are drinking rotten fruit juice!
