Grape Leaf Identification

Guide

• Frechman Pierre Galet is the go-to scientist for grape leaf identification. His book "A Practical Ampelography" is a grape vine identification guide with illustrations and can help your identification efforts.

Shape

• Leaf shape can help you identify the grape variety. Some leaves are wider, more like a maple leaf, while others seem narrower and have longer points.

Cell Structure

• Examine the cell structure on your grape leaf: a close-knit cell structure may indicate a wine grape. If the lines on your leaf are further apart, you might have an eating grape such as Concord.

Color

• Knowing whether the grape is blue or green can help you identify the vine. Wait until the grape vine flowers and fruits to identify difficult plants.

Considerations

• When they're young, grape vines and grape leaves may resemble other plants. If you're unsure whether a wine is a grape vine, examine the tip for curling tendrils; these indicate grape vines rather than another plant.
