Dear Dr. Vinny,
Can a wine that is enclosed with a Stelvin screw cap be corked? Is this ever possible?
—Jean-Paul, Norwalk, Conn.
Yes, a screw-capped wine can still be "corked." It's possible for the chemical TCA (2,4,6-trichloroanisole) and its corky, nasty odors of musty, damp cellars and wet newspapers to affect a winery's entire cellar, ruining whole batches of wine—which can then be topped with a screw cap. But eliminating corks rules out one of the biggest threats of TCA contamination.
