Selecting an appropriate grape variety is a major factor for successful production in Indiana and all parts of the Midwest. There are literally thousands of grape varieties available. Realistically, however, there are only a few dozen that are grown to any extent worldwide, and fewer than 20 make up the bulk of world production. Consistent production of high quality grapes requires properly matching the variety to the climate of the vineyard site.
This publication identifies these climactic factors, and then examines wine grape varieties and table grape varieties. Tables 1, 2, and 3 provide the varieties best adapted for Indiana, their relative cold hardiness and disease susceptibility, and their yield performance at two test locations in the state.
