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.
A corked wine has nothing to do with bits of broken cork floating in it. “Corked” means that a specific cork has been infected with snappily titled 2,4,6-trichloroanisole (TCA for short). It ...
A wine fault is a sensory-associated (organoleptic [1]) characteristic of a wine that is unpleasant, and may include elements of taste, smell, or appearance, elements that may arise from a "chemical or a microbial origin", where particular sensory experiences (e.g., an off-odor) might arise from more than one wine fault. [2] Wine faults may ...
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).
Compared to cork, screw caps reduce the wine faults of oxidation and of cork taint, although it is possible to find TCA contamination in a screw cap bottle. [2] Screw caps are generally perceived as easier to open and they are much easier to reseal.
Smoke taint is a broad term for a set of smoke imparted compounds found in affected wines, constituting a wine fault.Increasing incidences of smoke tainted wines are an important issue, given the recent occurrences of wildfires or bushfires in wine grape producing regions during the growing seasons.
In no-fault states, drivers have personal injury protection (PIP) insurance, which covers their medical expenses and related costs, no matter who caused the accident. However, drivers are still ...
