How can I tell what type of grapes I have?

[Smoke]

I inherited 3 black/ blue grape vines with the horse I bought 3 years ago. How can I ascertain what varietals they are? My local extension office stopped doing so analysis so, I believe I’ll have zero luck getting them to test them for me.

start with leaf shape and size (ampelography)

then distance between nodes

then skins - e.g. slip skin or not

then berry size

then seedless/not seedless

finally colour of young shoots

Is there a lexicon that I can use to compare these attributes?

Smoke, I suggest getting on YouTube and searching "Identifying grape varieties" and you will get a number of replies. Here is one I found quickly with about 2 minutes of searching:



You can take your laptop to the garden and do the research real time.

Go to the nurseries near you that sell grape vines when the bud out into leaf and compare your young leaves to theirs. You may get a match.
