Grape vine variety

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.

Grapes

Is it ok to cut back grape vines to within two leaves of the grape clusters to keep the grape vines from growing too long?

Muscat grape disease (happens every year!) I'm devastated !

OMG ! Please help, my beautiful Muscat grapes get this disease every year ! They are in a 'half-barrel' type container, 3 containers and all three get this every year. I purchased The grape vines at least 5 years ago from a local very reputable family nursery. I'm now thinking that it is the soil that is contaminated ?! How can I send you a few pictures???

Grapevine flowers

Both of my grape Vines have flowers that have burst now, do they get pruned off or are the grapes coming behind them? Do I prune off some of them to make the grapes bigger on the other stems? This is the second year, and I have more this year than last.

Cuttings identification

Hello, We have some cuttings from a local backyard vineyard. We have perhaps Pinot Noir, Cabernet Savignon and Merlot. They are ready to go into the ground. Note, these are just some cuttings no root stock. We thought we would just see if they grew and they did. Vines are in one gallon black pots and are about 12"tall. NOW we want to identify them because we are planting about 15 plants along with a few native vitis californica. We are in Saratoga, CA. This is for landscape and enjoyment. Since the leaves are not mature, we are having some difficulty doing identification. Some plants are taller and more upright with leaves coming out on opposite sides of the stem. Others are shorter and shoots are bunched from one bud. What else will help us identify them? Will leaf veining help identify? OR the under side of the leaves? Again, shape of leaf is helping but not definitive because we are not expert. Thank you. Cindy
