Sonic Youth Decanted, or how we ended up in the Washington Post

On December 10th, we were featured in a Washington Post Online  article disputing the claims made about the Sonic Decanter. The article is fair and comprehensive. It is a much needed antidote to the marketing bromides that have been swirling around the Sonic Decanter for the last few months.

Our involvement in the  story began with this blog post, which was originally published on November 24th.  I wrote this article after  Will Kanaley  posed a question about the device on our “Ask Us Anything” forum. Prompted by Will, I looked into the Sonic Decanter and it’s marketing claims. I did not like what I saw, or how the media was drinking up the marketing claims with little if any of their normal skepticism. My research turned into this blog post, and what I found was pretty damning.

We got some social media love, and a few angry mentions (of course) in a forum or two.  Within a few days, Tuan Nguyen  of the Washington Post called me up. I  talked with Tuan for several hours about my concerns with the Sonic Decanter. The article he wrote is well worth a read.

My original post starts here:

Wine Gadgets

Every few years, a new wine gadget is invented.  In 2005, there was the “Wine Magnet” it’s marketing stated that it would ” improve the taste of wine… making it smoother, less bitter and more refined… aging wine to perfection.”  In 2007 came the “Wine Aerator” with it’s promise of adding oxygen to wine as you drank it (as if this didn’t happen already because, you know, science).  Dozens of proprietary wine glasses and decanters have come our way, all with claims to make wine taste better than it should.  At the Wine School, we have disproved all these contraptions, and in classes like [link id=”14823″ text=”Sommelier Secrets“] we show how absurd their claims are.

Sonic Decanter

Recently, a new wine gadget has popped up on Kickstarter. It’s called the  Sonic Decanter . As of this writing, it’s met it’s funding goal, and in fact has exceeded that goal by nearly 200%.  The  popularity of this device has been spurred on by articles in Huffington Post, CNET,  The Times,  and Gizmodo.  Most  of the articles extolled the virtues of the device, saying it made wine taste better. Sadly, none of the journalists took a hard enough look at the creator’s claims.

How the Sonic Decanter Works

The creators of the device  claim that it uses sonochemistry to change  the molecular structure of wine.  In other words, the device shoots  ultrasound waves into the wine to  alter flavor compounds. They claim this change is beneficial to the taste.

They claim the device lowers a number of naturally occurring elements in wine , including sulfur dioxide, anthocyanins, and volatile acidity. They also claim to reduce pH of the wine, as well. Here is their chart they include on their kickstarter campaign:

Here are the claims from various sections of their  kickstarter page:

When used on wine the Sonic Decanter® promotes further extraction of flavors, aromas and mouth feel from interactions among phenolics and anthocyanins which results in smoother more integrated mouth feel and a smooth, flavorful lingering finish.

When using the Sonic Decanter®, wine becomes a more homogeneous liquid with improved sensory characteristics and an improved open bottle “shelf life” in a very short time of treatment. Using the Sonic Decanter® allows for a more energetic reaction between the molecules and thus a more complete molecular change. In addition the natural gases including oxygen and sulfur dioxide (SO2) are expelled from the bottle, pH is reduced and other components are modified.

There is no specific time limit for drinking the wine after improvement with the Sonic Decanter. We have had wine that was treated, tasted them re-corked and found the same wonderful characteristics 4-6 days later. Of course this requires that the wine be re-corked and stored properly between tastings.

The Sonic Decanter applies optimized levels of both pressure and temperature via ultrasonic energy. The process is conducted independent of external temperatures and pressures and provides a means of obtaining changes in molecular structure, at microsecond intervals, in microscopic areas throughout the liquid. The complete agglomeration of wine components results in a smoother taste and enhanced overall wine experience. Moreover, the stability of the molecular change extends the peak periods of taste and bouquet increasing the drinkable shelf life of the wine.

Let’s break this all down, and see if the claims hold up. To be clear, I have not used the machine in question.  I am relying on the Sonic Decanter Kickstarter page. If the people behind Sonic Decanter have more technical  information about the product, I would gladly re-examine this issue. However, with what I have seen, I believe their claims to be dubious.

1. Reduces sulfur dioxide.  This is technically true, but this already happens when you open the bottle. Also, they didn’t even bother fixing the typo (sulfar dioxide) on their image.

2.  Reduces oxygen levels from wine. This claim makes little sense. O2 levels in wine are microscopic. In fact, their claim that oxygen is pushed out of the wine would negatively impact the flavor of wine: exposure to oxygen is the single most important factor in increasing wine flavors when opening a bottle of wine. This is why sommeliers decant wines.

3. Reduces (or changes) levels of anthocyanins.  Anthocyanins are the pigmentation of red wine. Along with other polyphenols, they give  red wine it’s sensation of dryness and texture in red wines.  If it actually changed the type or quality of the anthocyanins, the biggest difference would be to the color of the wine.

4. Softens the tannins. Wine gadget promoters typically proclaim that their devices “soften” red wine flavors. This is simply very easy to do. Heat the wine in a microwave for 30 secondow setting will do the same thing.  Shooting the wine through a blender will do the same thing. Or (on my strong  recommendation) simply opening the  bottle for an hour before drinking will do the same thing.

5. pH is reduced.  To reduce pH means the machine is making the wines more acidic.  This isn’t impossible, but it doesn’t jibe with their other claimes. It would make the wine taste sharper and crisper, not rounder or fuller. It would make flaws in lower priced wines more noticeable.

6. Improve shelf life. This claim seems impossible on it’s face.  Breaking down anthocyanins and altering it’s acid levels can only reduce it’s ability to stave off  oxidization and infections. It would only work if it totally neutralized the wine, destroying the  majority of biological elements in the wine. Of course,  flavor in wine is biological in origin…

7. Reduces Volatile Acids.  These are not present in any meaningful way in wine.  This was a problem in inexpensive wine 20 years ago, but it’s very rare today.

 

For any journalist who wants to test Sonic Decanter, please follow my standard rule in testing wine gadgets: as in any scientific study, there must be a control subject. That control subject MUST always be a bottle of the same wine, decanted an hour before and served at 65 degrees Fahrenheit.
