Grapes
 

I have three varietals of grapes on my property
. From the attached picture; on the Left are Concord. It's the ones in the middle which seem a bit sweeter and the little ones on the outside that look like Concard but are smaller and very dry tasting that I am hoping someone can identify .

Thank You

Try to match up the leaves too. I was able to identify the ones in our yard easier by the leaves and the clusters than the actual grapes. UNH or some local vineyards may be a good place to email as well.
