NAPA, Calif., After more than ten years of research and development conducted in collaboration with the Institute of Vine and Wine Sciences (ISVV) in Bordeaux, Seguin Moreau is proud to unveil the QTT barrel.
QTT, or the molecules quercotriterpenosides, are a new family of oak compounds found to play a key role in sensory profiles of wines aged in barrels and are responsible for the sensation of “sugariness” and sweetness in dry wines.
The discovery of QTT and of a structurally close sub-family Glu-AB, molecules characterized by their bitterness, provide scientific explanations for oak-aged wines’ taste balance.
