Chemical structure of 2,4,6-trichloroanisole (TCA), the compound primarily responsible for cork taint. Cork taint is a broad term referring to an off-odor and off-flavor wine fault [1] arising from the presence of 2,4,6-trichloroanisole (TCA), a chemical compound that represents one of the strongest off-flavors, and one "generated naturally in foods/beverages", in particular wines, that ...
Over the last two decades, the incidence of mouldy and musty off-flavours in cork-sealed wines has increased significantly. 2,4,6-Trichloroanisole (TCA) has been identified as the primary chemical responsible for cork taint. The human olfactometry threshold for TCA is 4–10 ng L−1 in white wine and 50 ng L−1 in red wine.

Cork taint A type of wine fault describing undesirable aromas and flavors in wine often attributed to mold growth on chlorine bleached corks. Coupage A custom of "enormous antiquity" of mixing a little good wine with much bad wine and calling it good.
While many bulk wines use screw caps -- which is likely where the stigma originated -- a screw cap is by no means and indicator of the quality of your wine.
Alternative wine closures are substitute closures used in the wine industry for sealing wine bottles in place of traditional cork closures. The emergence of these alternatives has grown in response to quality control efforts by winemakers to protect against "cork taint" caused by the presence of the chemical trichloroanisole (TCA).

Corks and screw caps have similar functions: to keep wine from going bad. But choosing one or the other can be divisive. Many argue that corks are the key to excellent aging.
Cork cambium (pl.: cambia or cambiums) is a tissue found in many vascular plants as a part of the epidermis. It is one of the many layers of bark, between the cork and primary phloem. The cork cambium is a lateral meristem and is responsible for secondary growth that replaces the epidermis in roots and stems.
