Greece's wine history goes back thousands of years but it's only over the last 40 years that the industry has got back on track, with the production of outstanding white wine as well as very good red, from both indigenous and international varieties. I interview Dionysi Grevenitis, who has imported Greek wines for the last decade as the country has improved its international reputation. We talk about where Greek wine has developed in that time, as well as Greece's great white variety: Assyrtiko.
