Details
In the early 1800s, Isabella was widely planted in the North Atlantic and New England States where Catawba could not reliably ripen, but it fell out of favor after Concord was introduced. Isabella can withstand tropical and sub-tropical climates and is the most widely planted grape cultivar in southern Brazil and is used for both juice and wine.

Training System
Top Wire Cordon (TWC) Download Top Wire Cordon PDF

Top Wire Cordon is arguably the most efficient training system for grapes, especially for procumbent or downward growing cultivators, especially those not prone to late season fruit rots due to shading of the fruiting zone. Summer labor is much less than that required with Vertical Shoot Positioned (VSP) training as shoot positioning and leaf pulling are generally not required. Learn More
