Pre-Bottling

2,4,6-Trichloroanisole (TCA) is a chemical compound that is a chlorinated derivative of anisole. TCA is a fungal metabolite of 2,4,6-trichlorophenol, which is used as a fungicide.

TCA is the chemical primarily responsible for cork taint in wines. The odor of TCA is not directly perceived. Instead, the molecule distorts the perception of smell by suppressing olfactory signal transduction. The effect occurs at very low concentrations (single parts per trillion), so even very minute amounts of TCA can be detected. It causes unpleasant earthy, musty and moldy aromas.
