Hi, it works in general, although I agree with Pat's comments above. I have attached a review for you to consider - just made a bit more lean here and there, and changed some emphasis. Nothing major. Good luck.
The Douro Valley is one of the most well known wine regions because of the Port wine (grown there) but there are vineyards all over the country, many people have micro vineyards and produce a very small quantity just for their own consumption. My father was one of them. I stll have relatives around Tomar that produce their own wine, so much better than anything you buy in a shop, specially when you fill a glass directly from a little wooden tap in the cask. After bottling it is like frozen peas: nice but not as fresh as when they come out of the pod. (Uhm... I think I've just got myself another good line for Mariza. LOL)
I also buy direct from producers both locally and the Valtellina region where my mother was born. On the subject of Port, I always look forward to one of my wife's colleagues at Lisbon University who visits twice a year. Especially, the Port produced by a female-owned vinery (the name slips my mind at the moment).
