The Northern Grapes Project Webinar Series

 “Building the Perfect Body: Tannin Strategies for Red Hybrid Wines”

 Tuesday, March 10th, 2015
12:00 Noon Eastern (11:00 am Central)
7:00 pm Eastern (6:00 pm Central)

 Wines produced from red hybrid grapes are often criticized for light body, poor structure, and insufficient ageability.  The recent discovery of tannin-binding compounds in hybrid grapes suggest that traditional processing techniques, like extended maceration or enzyme treatments, are largely ineffective at increasing tannin concentrations in these wines. Exogenous tannin products offer one means of tannin enhancement, but guidelines for most products are designed for V. vinifera cultivars and are inadequate for hybrid wine production.  This webinar, presented by Anna Katharine Mansfield of Cornell University, will review the current understanding of phenolic extraction and loss in hybrid wine fermentations, and the latest findings in optimized tannin addition.
