HAVE YOU EVER stuck a spoon in an unfinished bottle of Champagne, stuffed Saran wrap into a decanter of corked wine or spun a Cabernet in a blender?
These are just a few of the tricks oenophiles have been known to employ to save a wine from being poured down the drain.
Wine collectors regularly bandy about the Saran wrap technique as a way to remove 2,4,6-trichloroanisole (TCA), or cork taint, from a wine. TCA, a chemical compound occasionally found in corks (hence the term “corked”), can impart a dull or even musty character that is perfectly harmless but unpleasant to consume. Polyethylene, found in plastic wrap, absorbs it.
“The non-polar TCA molecule has a high affinity for the polyethylene molecule,” Rich Olsen-Harbich, winemaker at Bedell Cellars in Long Island, N.Y., wrote in an email, explaining how the trick removes the taint.
