A very fine vintage

In the nearby farm stand where they grow organic vegetables in fields outside the door, and will harvest to your request, they also serve lunch. (The subject of another edition of Itch.) John and I had lunch there several days ago with friends and talked to the owner about the red wine he was serving, made from grapes he had grown and harvested. Our friend wanted to know what type of grapes were in it—pretty much the first question for any wine-maker. The owner responded that he had no idea. They were grapes that were growing on his property. And that he had added some white grapes into it as well.
