Bernard, I'm not sure where you live, but the grapes I grow were chosen specifically for our climate which has HOT, windy summers and MILD winters. They are all red wine grapes. Red wine is easier to make. White takes a little more chilling and work, so we kicked that idea to the curb, and just buy our white wine at stores. We grow Touriga National, Carigne, Cabernet Sauvignon No. 8, Mourvedre, Tempranillo, Zinfandel, Malbec and a few others.
When first planning our vineyard, I researched vines from other countries with our same climate. I then looked here to find out where to purchase them in the USA. Many, I started from cuttings from UC Davis. I also purchased Grafted vines from dealers in the US.
That link is a valuable resource for finding the heritage and information on any grapevine. It states if it's a table or wine grape. What is the difference? Table grapes are seedless and not as sweet. Wine grapes are killer sweet and loaded with seeds. The yeast thrives on the sweetness which makes for good wine. It gobbles up all that sweet, and turns it into alcohol. Table grapes are not sweet enough for wine.
Aaron, I am thinking of getting some Rogers Red cuttings and sticking them down near a tree (to climb) by our seasonal stream at the bottom of our hill. At least it will get water down in that area, but it's an aggressive vine and although it's pretty, don't want it anywhere near anything I care about. Jim and I fight all the time about this "beautiful" worthless pink flowering bush on the property. For one month it's gorgeous. Then it's taking up space where I could put a fig tree!
Different strokes.
