Scientists Develop 'Artificial Tongue' To Detect Fake Whiskies (theguardian.com) 99

Scientists have developed an "artificial tongue" that can differentiate a young whisky from an 18-year-old single malt. "The team, based in Scotland, say their device can be used to tell apart a host of single malts -- a move they say might help in the fight against counterfeit products," reports The Guardian. From the report: Writing in the journal Nanoscale, the team describe how their artificial tongue is based on a glass wafer featuring three separate arrays, each composed of 2 million tiny "artificial taste buds" -- squares about 500 times smaller than a human taste bud, with sides just 100nm long. There are six different types of these squares in the device, three types made from gold and three from aluminum. While one type of gold and one of aluminum are essentially bare, the surface of the other types are coated in different chemical substances.

Each of the three arrays contain one type of gold and one type of aluminum square. When light is shone on an array, it interacts with the electrons at the surface of the squares, resulting in dips in the reflected light which can be measured. These dips appear at slightly different wavelengths depending on which type of square the light interacts with. Crucially, these dips shift depending on the liquid surrounding the arrays. The upshot is that each liquid gives rise to its own "fingerprint" of measurements. That means the device can be used to tell apart different liquids -- and even identify them if they have been recorded before -- without revealing their makeup, rather like our own tongues do.

    I volunteer my services for determining whether a whisky is truly an 18-year-old or not.

          That is the problem they use nasty peat that tastes like a dissolved Asprin. There are basically two inexpensive whiskies to try. A jameson 12yr (you won't find it, so buy an 18 to find out) and Makers. Remember to sip not "drink" like they do in madmen. If you still don't like it then move on with your life, if you do like them then your issue isn't whisky but the kind of whisky. I have no idea why people became obsessed with Scotch but one on one I've gotten most to admit it is really a social thing to be

    • No, that would be gin...

    • Try a green tea mix shot. The primary ingredient is Jamison whisky. But you can't taste it with the rest of the mix. Fuck you up big time though if you do enough of them.

      Ever smelled the inside of a whisky barrel? Explains a lot.

      Sometimes tastes change. I hated all the whiskey variants for years. I'd drink just about anything else but couldn't stand it. Then one day I had some sort of whiskey mixed drink and it didn't taste too bad, and a year later scotch was my favorite drink. No idea what changed, but it stopped being horrible to me and started being tasty.

      Of course your taste buds might also not change, or not in that way. It may be worth testing now and then, just to see.

    I personally don't care if something is "counterfeit"...

    At the end of the day, it's down to taste.. Does one taste better than the other, and is the improvement sufficient enough to justify the price difference?

    If people are buying the cheap stuff it's because they don't think the difference is worth paying such a high price for (or they might actually prefer the cheap stuff).

      Sure, for the consumer looking to buy a single bottle does it really matter if you've been sold a £10 knock-off for £50 if you can't tell the difference and the taste meets your expectations? Yeah, there's the principle of the thing, but ignorance is bliss, right? You might even prefer the knock-off, come to that. And if you deliberately bought the knock-off for £10, then you can only expect to get what you pay for and hope to be pleasantly surprised. If you're looking to buy several h
      • If you're a whiskey afficionado, or just want to show-off, and are paying out those kinds of sums for a bottle then you'll absolutely want to be sure you've got the genuine article before you finalise the sale

        Is it customary to allow the buyer to check a sample before the auction ? And if so, can't you just taste it yourself to see what kind of price you're willing to pay ?

        • by Zocalo ( 252965 )
          In some instances it might be, for rarer bottles and sales at auctions almost certainly not, especially if the bottle(s) are unopened. There might also be some form of provenance available to provide some assurance as to authenticity, sales receipts and so on, but YMMV as to how much trust you put in those depending on what they are, and there's always the possibilty of pairing the provenance of a genuine bottle with a fake.

          The ideal time to use the tongue would be immediately after concluding a purchas
          • The problem with this electronic device is that it just seem to give a 'fingerprint', not an actual verdict whether it actually tastes good. That may be good enough to identify certain brands and distinguish them from off-brands, but it doesn't guarantee that it can say anything useful about very rare and unique products.

            Just like you could identify Usain Bolt by his fingerprint, but you can't tell from a fingerprint if a random person is a talented sprinter.

        I'd be more interested if they could produce a pocket sized one that can determine the precise urine content of any beverage.

    • "At the end of the day, it's down to taste.. Does one taste better than the other, and is the improvement sufficient enough to justify the price difference?"

      Indeed. There are some really crappy 18yo whiskies out there, and some marvelous 5yo whiskies. Add to that: some kinds of whisky (like heavily peated Islays) are just better young. IMHO, of course, as there's a lot of personal taste and personal preference involved.

      There are too many people who are way too "brand aware". For example, anything with the n

    • Distilled alcohol could have methanol in it if it wasn't made well. It isn't quite the same as buying counterfeit Oakleys at the Farmer's Market. More like buying mystery meat.

      I personally don't care if something is "counterfeit" ...

      That's precisely why the vendor does, because your sense of taste is so diminished, you don't even stop to ask yourself if the label on the bottle is full of shit.

      I personally don't care if something is a sketchy knockoff, so long as the label doesn't advertise my indifference to world & dog.

  • it matters in a way to detected forgeries, but other than that?
    if the human tongue isn't able to detect the difference, should it even matter what you are drinking?

      who says the human tongue can't tell the difference? But there's only so many people who are going to be interested in taste testing rotgut, much less practice enough to be able to accurately identify the rotgut despite a misleading label.

    • Can you taste the difference between alcohol, methanol, or ethanol? You might not be able to, but the effects of each are certainly different.

      If it is a counterfeit, you're trusting the criminal with your health. That matters.

  • ...if you need a precise laboratory-caliber sensor to tell the difference between that $500 whiskey and a $15 bottle, why are you wasting the money on the expensive bottle (except in Ponzi-like hopes that there will be another even more gullible rube further down the line)?

    • by suutar ( 1860506 )

      I don't think it's that they need a precise sensor to tell there's a difference, they need a precise sensor to tell where the cheap stuff in the expensive bottle really came from since the label is lying.

  • So is whiskies the plural of whisky or the plural of whiskey ?

    • From the Grammarphobia Blog [grammarphobia.com]:

      In Scotland, they make Scotch "whisky" (plural "whiskies"), but in Ireland they make Irish "whiskey" (plural "whiskeys").

      American and British dictionaries generally observe this distinction when referring to these two products. But then the dictionaries go their separate ways.

      In referring to versions of the liquor manufactured in other countries, British dictionaries spell it "whisky." Some US dictionaries prefer "whiskey" while others accept both spellings as standard.

      Why the difference? We haven't found a definitive answer.

      For details, click on the link. To avoid the pain from tying your brain into knots, I suggest downing a few bottles of your favorite whisky or whiskey first.

  • One small step on the long path to duplicating the fine whiskeys, er, whiskies, of the past and engineering better ones in the future.

    By the time Scotty is making hooch in the Enterprise engine rooms, he should be able to make a very fine "18 year old" whiskey in far less time.
