Grape Breeding and Enology

  • panoramic wines

Welcome to the Grape Breeding and Enology project website!

Located at the University of Minnesota-Twin Cities, we conduct research in the Department of Horticultural Science and at the Horticultural Research Center.  Our focus is on grapevine cultivar development which includes: wine grapes, table grape varieties, and ornamentals that survive and thrive the cold-climate conditions.  We also focus on understanding the mechanisms of disease and pest resistance so that we incorporate these traits as a way to improve sustainability for Minnesota growers.  In addition to developing grapes, we focus on developing and teaching enology best practices for cold-hardy grapes.

Beta-glucans in wine cause filtration problems

Vintage 2019 MN grape wine filtering issue - UMN Grape Breeding & Enology Project

by Drew Horton, Enology Specialist

The University of Minnesota Grape Breeding & Enology Project has recently received anecdotal reports about difficulty in filtering vintage 2019 wines made from the Frontenac “family” of grapes: Frontenac, Frontenac gris and Frontenac blanc, and possibly some other grape varieties as well. Some winemakers have reported increased problems with filter and membrane clogging, especially with cross-flow type filters.
