 French-American hybrid grapes were developed and saw some use in Europe, but more important was the practice of grafting European grapevines to American rootstocks to protect vineyards from the insect.The practice continues to this day wherever phylloxera is present.Today, wine in the Americas is often associated with Argentina, California and Chile all of which produce a wide variety of wines, from inexpensive jug wines to high-quality varietals and proprietary blends.
