About

The Mansfield Research Lab, led by Professor Anna Katharine Mansfield, operates at the intersection of enology, chemistry, sensory science, and viticulture. The lab focuses on addressing practical challenges faced by small, local wineries, aiming to solve pressing questions within the wine industry while also exploring fundamental unanswered questions in the world of wine. Recent research efforts have included studies on fermentation nutrition, fermentation kinetics, yeast strain identification, and phenolic composition. On a broader scale, the lab investigates how these variables influence consumer perception and acceptance of wines. The lab's work reflects a commitment to both applied and fundamental research in enology, contributing valuable insights to the field.

• A next-generation marker genotyping platform (AmpSeq) in heterozygous crops: a case study for marker-assisted selection in grapevine

  Horticulture Research · 2016-02-17 · 93 citations

  articleOpen access

  Marker-assisted selection (MAS) is often employed in crop breeding programs to accelerate and enhance cultivar development, via selection during the juvenile phase and parental selection prior to crossing. Next-generation sequencing and its derivative technologies have been used for genome-wide molecular marker discovery. To bridge the gap between marker development and MAS implementation, this study developed a novel practical strategy with a semi-automated pipeline that incorporates trait-asso…

• Next Generation Mapping of Enological Traits in an F2 Interspecific Grapevine Hybrid Family

  PLoS ONE · 2016-03-14 · 52 citations

  articleOpen access

  In winegrapes (Vitis spp.), fruit quality traits such as berry color, total soluble solids content (SS), malic acid content (MA), and yeast assimilable nitrogen (YAN) affect fermentation or wine quality, and are important traits in selecting new hybrid winegrape cultivars. Given the high genetic diversity and heterozygosity of Vitis species and their tendency to exhibit inbreeding depression, linkage map construction and quantitative trait locus (QTL) mapping has relied on F1 families with the u…

• Reaction Kinetics of Monomeric Anthocyanin Conversion to Polymeric Pigments and Their Significance to Color in Interspecific Hybrid Wines

  Journal of Agricultural and Food Chemistry · 2017-02-07 · 38 citations

  article

  The color stability of red wines produced from interspecific hybrid grapes, which is partially dependent on anthocyanin diglucosides, is not well understood. In this study, the rate of decrease of monomeric anthocyanins as they polymerized to polymeric pigments due to the presence of excess catechin and acetaldehyde was measured in model wine using HPLC. Colorimetry was used to measure L*, a*, and b* values, hue angle, and change in color (ΔE). Concentrations of individual diglucosides decreased…

• Soil Nitrogen Fertilization Increases Yeast Assimilable Nitrogen Concentrations in ‘Golden Russet’ and ‘Medaille d’Or’ Apples Used for Cider Production

  HortScience · 2020 · 11 citations

  The recent growth in the U.S. hard-cider industry has increased the demand for cider apples ( Malus × domestica Borkh.), but little is known about how to manage orchard soil fertility best to optimize horticultural performance and juice characteristics for these cultivars. To assess whether nitrogen fertilizer applied to the soil can improve apple juice and cider quality, calcium nitrate (CaNO 3 ) fertilizer was applied at different rates to the soil beneath ‘Golden Russet’ and ‘Medaille d’Or’ t…
