A very resistant red wine variety

​

Frontenac is a very disease resistant variety with good resistance to powdery mildew and near-immunity to downy. Initially acids are high, but often drop dramatically late in the season. Fortunately, the pH does not often rise to dangerous levels. When grown in colder area the berries must be left on the vine long enough to mature fully. It produces only a moderate number of tendrils, which facilitates vine management.
