tribromoanisole

The chemical compound (exact name 2,4,6-Tribromanisol = TBA) is similar to the known trichloroanisole (TCA) by microbial degradation of tribromophenol. The tribromophenol is used for wood impregnation and as a fire retardant additive in the production of cardboard, dyes and plastics. Since these materials are also widely used in the food industry and in viticulture, the substance can come into contact with cellar machinery or bottle caps and so get into the wine. TBA causes a musty-dusty, the classic TCA-caused wine defect corked very similar odor and taste, The Perceptual threshold in wines is about 3 to 4 ng / l (ng = billionths of a gram), so rather at even lower levels than the TCA.
