suberista

A suberista is a wine taster who specializes in identifying and evaluating the presence of cork taint, a common fault in wine caused by the chemical compound 2,4,6-trichloroanisole (TCA). This compound can leach into wine from contaminated corks, imparting undesirable aromas and flavors. Suberistas are trained to detect even trace amounts of TCA, which can manifest as musty, damp cardboard, wet dog, or moldy newspaper notes. Their expertise is valuable in quality control for wineries and vineyards, helping to ensure the integrity of their products.

The ability to identify cork taint requires a highly developed olfactory sense and a deep understanding of wine aromas. Suberistas often participate in sensory panels and blind tastings to refine their skills. They can distinguish cork taint from other wine faults or characteristics. The economic impact of cork taint can be significant, leading to entire batches of wine being rejected or devalued. Therefore, the role of a suberista is crucial in preventing financial losses and maintaining consumer satisfaction. While natural cork stoppers are the primary source of TCA, it can also be introduced through other winery materials or even the environment. Modern winemaking practices often involve rigorous testing of corks and other materials to minimize the risk of contamination.
