Grape vine variety

Asked September 11, 2019, 5:57 PM EDT

We moved into a house that has 2 large established grape vines trained on an overhead trellis. Can you help identify what variety they are? Below are some pictures of leaves and grapes. The grapes were all finished by mid August most of them do turn red on ripening, but not all.

Your best bet is to bring your grape cluster and some leaves to the Santa Clara Extension office to identify any insect or fungal problems and then possibly identify the cultivar of grape:
