Chemists Build App That Could Identify Cheap Replacements For Luxury Wines 206
schliz writes "Australian startup Wine Cue is combining the chemical composition of wines with customer ratings for what it hopes to be a more objective wine recommendation engine than existing systems that are based on historical transactions. The technology is likely to reach the market as a smartphone app, and could be used to identify cheap alternatives to expensive bottles."

If there is one thing that needs more objectivity its wine tasting.
Too often the results are the opinion of the person who bought the bottle, and too seldom is there truly blind taste testing by people not already familiar with the vintage.

Even with blind tastings there is subjectivity, as people sense of taste and smell is quite varied. I tend to be good at picking up secondary aromas (not the primary fruit) but amd not as good at picking out some of the subtle fruit smells. It all come down to chemicals ... esters and other compounds, that can be measured objectively, but for now is still quite expensive to do accurately. Any good sommelier can generally pick out a cheaper example of an expensive wine for you based on what you like though. It may not be *as* good as the expensive one, but it is a game of diminishing returns for the most part, although it is occasionally possible to get a *better* wine for less money. Wine sells for what the market will bear, based on origin, availability, and reputation.

No, what we can't do is build a violin that self-proclaimed audiophiles say is as good as a Stradivarius during NON-BLIND TESTS in UNCONTROLLED ENVIRONMENTS. If you administer proper double-blind tests then you'll find that there's no difference.

Talk to a metallurgist. Modern steel actually performs better. I'm not sure how much effort has been given to duplication, but why try to duplicate something when you already have a better replacement?

I'm not a wine snob, but I know there are certain things that sometimes you *can't* replicate. [...] I'd argue that fine liquors -- wines, whiskeys, etc... fall into that category. I'd say it's almost an art form.
Detailed studies [wsj.com] of professional wine judges in blind tastings have shown that prizes from contest to contest are so random that they might as well be picked from a hat. And the average professional judge, tasting the same wine on consecutive days, would on average only be able to narrow the rating to within 8 points on a 20-point scale.
Other studies have even shown that professional tasters often fare pretty poorly even in tests like, "Taste 3 wines, tell me which 2 are identical," or that when given white wines dyed with red food coloring, they start spouting out the nonsense about "flavor notes" and "nose" that would be appropriate for red wines rather than whites.
Given this information, it's pretty clear that even the so-called "expert palettes" don't know what the hell they're talking about.
So, I'm going to go out on a limb and say that it's pretty likely chemists could master the subtle art of getting a wine result that could satisfy even most professional judges in a blind test.

I've had some spectacular wines. No, no, not the wines that cost hundreds of euros per bottle. but wines that could be described as "WOW. I didn't know wine could do that". It would be nice to have an app that would suggest similar wines, based on a chemical spectrum instead of "that estate had a truly extraordinary summer, and more recent vintages have not faired as well."
If a particular chemical is playing around with my brain,I want to know about it and be able to invite it around again sometime.

It always amuses the hell out of me when people think there were these amazing ancient technologies so much better than anything modern. It is like they think various videogames and novels are real and that we study the knowledge of the ancients to advance what we have, despite all evidence to the contrary.
As you say, all this stuff is bullshit. In terms of violins we can, if anything, build even better violins today because of better material selection and manufacturing techniques. The thing that makes Stradivarius sought after is its rarity. It is a special thing to own one, as there aren't many. That then of course leads to a mystique and to people making bullshit claims.
Same kind of thing with Damascus Steel. It has been claimed to be able to do things like cut through a gun barrel, which of course it can't do (gun barrels are amazingly tough objects). We can do better with modern metallurgy and processes (like an industrial hammer forge). The reason there's research to replicating Damascus Steel is because it is neat, it was very advanced for the time and it would be of historical interest to understand how it was done. We can do better, and indeed do all the time.

Very interesting.

In fact, the only statistically obvious trend in the choices was that one of the Stradivarius violins was the least favorite, and one of the modern instruments was slightly favored.

Go and have a look at the metabolic pathways that yeast use to glean energy from sugars in wine/beer. It is truly staggering, and temperature, PH, timing and yeast variety can all play a part in preferentially modifying those pathways. As a result, there are a bunch of fermentation by-products, including different alcohol groups and esters. For example, I'm a beer brewer, and belgian yeasts are noted for producing "lolly banana" esters.
There is also a legitimate difference between cheap and expensive wine techniques - time spent cellaring, new versus second hand barrels, preservatives etc.
At the end of the day though that doesnt make a lot of difference - peoples tastes vary wildly and If you personally like the way it tastes then that's great, go buy it again. Whilst there is no such thing as a "cheap" or "expensive" flavour, if lots of poeple like the way it tastes, then you can call it "good" wine. If lots of poeple say it tastes like arse, then it's "bad" wine.
