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?

like all acquired taste stuff - it's all BS. If gasoline did not kill you then we would have people talking about how exxon gas is so much tastier. Since it is an acquired tastes; what taste good is what we force ourselves to like by repetition.
This was added to the Wine category even though it is about wine.
Seal the bottle of wine with a screw top. No spoilage by cork. And no, it does not cheapen the wine. That's how you get wine now a days in New Zealand and Australia.
When we first met she was charging $300/night. But after her taint got corked a few hundred times it didn't seem quite as appealing anymore so she was forced to reduce her rate down to $75/night. I'll forward her a link to this article so she'll know the experience wasn't unique to her. I never got involved with her romantically but she helped me resolve my dyslexia.
or the Columbia Crest Cab Sauv that sells in high volume instead of the $70 bottle that's been sitting around for a few months. That's for the Donald Trump types that have to impress their dates when they order, and then again when they send it back.
Unintentionally funny.

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.

If the wine is corked it is unacceptable for consumption. The cork will smell like walnuts and that is easily perceived. I was lucky enough to have had a good host at a tasting who rejected a bottle herself. I asked why, and she let me smell the cork. The "corked" smell is unmistakeable.
That is not the only reason for sending back wine. There are at least two bacterial afflictions related to poor winery cleanliness that merit a return: amertume and ropiness. Amertume makes the wine bitter and ropiness ruins the mouth-feel.
Sending back bad wine is not only sensible, it's a feedback mechanism for the winery that says they need to improve their cleanliness.
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...

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.
Beta is broken and the link to classic doesn't work. Stop wasting our time or there won't be anybody left here.
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?
If it's contaminated, it's bad anyways. So what...
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!
