Dr Andy Walker to Retire: Leaves Legacy of Grapevine Breeding,

UCD Professor/Geneticist to Retire June 29 June 02, 2021 University of California, Davis (UCD) professor and geneticist Dr. Andrew Walker will retire June 29 after more than 30 years on the Department of Viticulture and Enology faculty and as a winegrape breeder. Given the long-term nature of the grape breeding process, it s not surprising that some of Walker s more significant breeding projects came to fruition later in his career the release of five nematode resistant rootstocks in 2009, and the 2020 official release of five new winegrape varieties resistant to Pierce s Disease (PD). Reflecting the reality of his work, Walker titled one of his recent lectures, 30+ Years of Grape Breeding and Just Getting Started.   With additional winegrape cultivars in development in the Walker Lab being bred for both PD resistance and powdery mildew resistance, important new grapevine materials will continue to become available well after he retires.

Seguin Moreau Debuts QTT Barrel

Seguin Moreau Debuts QTT Barrel Posted on February 23, 2021 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. Previously the volume, sweetness and roundness seen during oak aging wine had been unexplained. Extensive research by the teams of Professor Denis Dubourdieu and Doctor Axel Marchal (ISVV) uncovered new correlations, which were followed by five years of studies and analysis first to determine with certain
