Frost Grape vines are impressive climbers, using many reddish tendrils to cling and wrap themselves around trees, bushes, and fences. Their leaves look similar to Muscadine Grape leaves, being smooth and green on top and underneath. However, Frost Grapes produce fruit much later than other Texas wild grape varieties. Its small, acidic fruit appear in clusters in early fall, well past the mid-summer season of Muscadine grapes.

Frost grapes aren't edible raw until after a frost. The cold weather triggers enzyme processes that break down the acids and build up sugars, turning them quite sweet. If harvested before then sweetening occurs you are limited to making jams, jelly, or wines from the still acidic fruit. Treat them like the highly acidic Mustang Grapes. Large, healthy Frost Grape leaves can be cooked and used like regular grape leaves.

In the fall Greenbriar vines produces tight clusters of black fruit, leading to misidentification. The Greenbriar fruit are non-toxic but they lack any flavor, being mainly just rubbery and tasteless. Remember, Greenbriar vines have thorns and they also have two tendrils at the base of every leaf. Frost Grape tendril appear on two nodes in a row and then skip one or more nodes. Frost Grape fruits grow in long, dangling clusters whereas Greenbriar fruits grow in ball-shaped clusters.
