TN: Dream-Taste in Action

This is fascnating. I tried to google up some info on how this thing might remove the TCA contamination. A problem that has vexed winemakers and drinkers for a long time. Here is some of their marketing blurb ... "Well, now there may be a way to preserve those "corked" bottles -- by removing the molecule called TCA -- which ruins the taste of your fine wine.

Two wine experts from the Burgundy region of eastern France have created a new device called the Le kit Dream Taste to preserve the taste of your "special" wine.

Gerard Michel is one of the inventors responsible for this new system that will be available this summer for the first time in the comfort of your own home.

His system is the result of twenty-five years of research. It is a physical process called 'ionic filtration' which absorbs the "polluting" molecules in wine.

The result of his work has the opportunity to impact the estimated 1.5 billion bottles of wine contaminated in the world each year.

Physics Not Chemicals in The Magic Bunch

The Dream Taste kit does not use chemicals.

The Dream Taste Kit removes the TCA (2,4,6 Trichloroanisole) molecule using a copolymer, a synthetic material that draws TCA molecules out of the wine."

Anyone have any insight as to how this copolymer pulls the TCA molecules out?

Ric, I believe if you do some searches here for "plastic wrap tca" you'll find some theories re how it would work. My personal opinion (based on the Saran wrap method) is that it's worth trying,but there are likely to be some oxidation issues just because it takes a while to work.

Precisely my point, Graham. Had this been a recently purchased wine, it would have been returned to the retailer; had it been of no great consequence, it would have gone down the drain. Instead, as a one-off chance at an aged Volnay that I'd purchased at auction, why not give it a rip? I don't know how expensive the Dream-Taste inserts are, but since they can only be used once, I won't make a regular habit of this...

If you put Saran wrap over your face....it would end the TCA also. You would not notice it any more. :-)

Ric, This is yet another example of a solid-liquid extraction of TCA. FWIW, you could get the same result by putting the wine into a separatory funnel with some hexane and extracting the TCA out (but who'd want to drink the wine afterward? ;-)) If, as Dale suggests, you review the thread about Saran wrap removing TCA, you can read much more of my blathering on on this topic. :P

Certainly not with everyday plonk but a good burg is a different matter! Graham
