Bruce Reisch joined the faculty of Cornell University in New York in 1980 and spent the last 40 years specializing in developing new grape cultivars as well as new grape breeding techniques. During this time his program released 14 new grape cultivars, 10 of which are wine grapes. In fact I have one of his most popular grapes, Traminette, growing with a persimmon tree in my front winegarden here in LA. Bruce was also Chair for over 10 years of the Grape Crop Germplasm Committee, a national committee overseeing U.S. Department of Agriculture efforts to preserve wild and cultivated grapevines. He has studied grapes all over the world, published many papers on a variety of topics in the realms of Grape breeding and genomics, Molecular genetic mapping, and Marker-assisted selection, and won awards for the excellence of his grapes and his career achievements.

Bruce talks about the qualities of most of the cultivars that were developed during his time at Cornell, and gives us a historical context and an overview of current practices and objectives for grape breeding. We also discuss the possibility, almost a thought experiment, of growing a seedling vineyard to mimic the genetic variation that happens as grapes propagate and grow without human influence in forest lands. There are so many juicy tidbits throughout this conversation, it’s pointless to start listing just a few. This is a fantastic, comprehensive introduction to hybrid grape culture and why it is the present and future of wine.

Links to grape fungal resistance tables:

(Please note: I offer these links as examples only of tables that give ratings on fungal resistance. Resistance is never absolute, varies from location to location, and is influenced by many factors including: climate, weather, care, trellising, micro-climate, soil health, and many other factors. I do not endorse either the information nor the sources of the information, and I strongly recommend gathering lots of information from many sources, especially from growers of the cultivars, in your region if possible.)
