- European growers grafted North American vines to create pest-resistant hybrids
- Hybrids are generally heartier and produce more fruit
- French laws often restrict the use of hybrids in classic wines due to tradition
- Crossbreeding Vitis labrusca with Vitis vinifera grapes led to pest-resistant vines with desirable characteristics
- In 1876, American grapes were successfully grafted onto European vines
