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."

      Very true. Stelvin closures, Plastic corks, glass stoppers, all superior. The really amazing part if all the labour that goes into each real cork. Cut, cleaned, bleached, sorted, the re-sorted, much of it by hand. It's actually amazing that they're so cheap. It really sucks when a bad $0.30 cork ruins a 60$ bottle of wine.

      I agree that wine drinkers are usually guilty of pretension, but let's not pretend like taste and price have "almost nothing" in common. If you go buy 4 random bottles of $8 wine and 4 random bottles of $20 wine, you'll taste a substantial difference even in a blinded test. I'd guess that 1/2 of $20 bottles of wine are enjoyable as opposed to about 1/5 of $8 bottles.

      That said, a good $8 bottle might be every bit as good as the good $20 bottles.

      Plastic corks, glass stoppers

      No, no. Those things suck. Plastic corks are like regular corks, except they don't get moldy and they're a royal pain to get out of the bottle. Glass stoppers are easy to get out unless you break a bottle opener on it by accident. They're also vaguely resealable.

      There are two modern methods that are amazing for wine. Screw caps are stupid easy to use, cheap, and resealable. Modern, pioneering winemakers that don't worry about what people think about the presentation use screw caps. (They also often make great wine at affordable prices.) The other method is the box (or rather, a bag inside a box). A box looks completely classless, but it's one of the best ways of storing wine because pouring wine doesn't expose any of the remaining wine to oxidation. This means you can make a (disturbingly compact) 3L box of wine and use it over the course of a week. Or two days. Or a month. The wine stays good. Mercifully, some people -- not all Australian -- are making good wine in boxes now.

      Do you know why the older wine gets the more expensive it is? Aging. As wine ages the taste becomes refined, and the aging process depends on oxidation. Corks are permeable which allows the oxidation process (aging) to continue. Using materials other that cork stops the oxidation process making the wine less desirable and reduces the price of the wine.

      I'm not sure that effect is oxidation, but otherwise, yes. The good way to do that is with a decanter, though, rather than just opening the bottle. The bottle's small neck limits airflow. If you're going to expose it to air, might as well do it fast.

      No, not really. Oenology research mostly says the oxygen that gets into the wine from the bottling is plenty enough to age for years, and extra oxygen is MUCH more likely to spoil the wine than improve it.

      There may be a very VERY slight percentage of wine aged for a very long time that might improve with a perfect cork letting in just enough oxygen to keep the aging going without spoiling it, but for the VAST majority of wine current research says it's (and by "it's" that's the the Bordeauxs, cabs, etc) probably at its best in 25 years. And it's a crapshoot as to whether anything older will be any good at all. For the ABSOLUTELY OVERWHELMING majority of wines a synthetic cork will be as good if not better.

  2. price vs. taste by King_TJ · · Score: 2

    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.

    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.
